It also has a nine story (full height) atrium that will be used to extract all of the exhaust air (i.e. supply OA to the floors and condition via FC units and pull exhaust air out of the top of the atrium). I'm aware that eQuest doesn't track air flows but I'd like to best approximate the atrium effects on the overall energy use of the building. Current approach: I've modeled each floor as a separate zone and I'm going to delete the floors and turn the ceilings into air-walls and link them to the zone above. Currently I'm conditioning all of the zones that make up the atrium but at some point I'd like to explore not conditioning these zones to more accurately approximate how we'd run the building. Comments? One alternate approach I've seen proposed is to replace all nine zones in the atrium with one full height zone - the advantage is the glass on the roof and upper walls can "see" the floor and walls in all of the zones of the atrium. However this won't let me later go back in and explore any variation of temperature with height. I think this might be important as I would expect the air at the top of the atrium to be warmer and cause more load on the top floor zones next to the atrium. -- Jason Quinn From jeremiah at cleantechanalytics.com Mon Apr 2 14:05:52 2012 From: jeremiah at cleantechanalytics.com (CleanTech Analytics) Date: Mon, 2 Apr 2012 14:05:52 -0700 Subject: [Equest-users] Advice on modelling nine story atrium across shells In-Reply-To: References: Message-ID: Sounds like a task that would be better done with single zone and analysed using CFD to me..

Make an assumption about how much load is displaced or only present in the plenum portion of the atrium. Then, put a portion of the glazing and loads in the plenum(s). You might for example assume that the bottom two floors are one conditioned zone, and the top seven floors are a large plenum. I believe the air in the plenum should pick up the heat from the glazing and loads placed in it. I would be cautious about using eQuest to predict what will actually happen in an atrium though.

Short of toying with the azimuth/orientation inputs, which it sounds like you've done, my next guess would be to compare the contents of your daylight sensor's inputs in the .inp against a known working model's - perhaps something will stick out as obvious. Also on re-reading, I wonder if it has to do with the orientation of your contributing window? Try toying with that as well... If messing with either alters the 0,0,1.0000001 coordinates in that message that'll be a strong clue as to where the problem lies.

As according to "Treatment of district or campus thermal energy in LEED v2 & LEED 2009", a virtual plant with default efficiency can be used. There are few questions regarding the COP as well as the thermal loss: a) The COP of cooling plant shall be 4.4 including cooling towers and primary pumps. Does it mean that chillers, cooling towers as well as primary pumps shall be sized with COP 4.4? how can we enter the pump and cooling tower efficiency with COP4.4? Or we just only need to input COP 4.4 for chillers while the others can use the rated efficiency in our design? b) How can we input the thermal distribution losses? What I suppose is that, Q=mcdT, so if there are 5% thermal loss, the dT loss shall also be 5%. Does it mean to enter 5% of design dT in the "supply loss dT" column? Or make it simple, just multiplying 5% to the energy consumption by space cooling is already sufficient? Thanks all.

Please confirm the values entered in the form and revise as necessary. Ensure all values are consistent between the form and simulation documentation." After more research I found out that my inputs from BEPU reports are correct on the LEED template but in the end the template calculates the MMBtu/year with an error of 0.25 % when comparing the template with the BEPS which is carried on to the cost. Now, the difference is just a couple dollars and is insignificant for the savings between the models but the reviewer has a problem with this.

I have been looking into the window/drapes functions, i.e. the possibility of changing blind positions over 3 different seasons. I didn't find, though, the possibility of switching on ambient conditions, as suggested by Michael. How can you do that? It's quite interesting the possibility of uploading an annual hourly schedule into the software. Do you think I can generate an excel schedule setting different values for some parameters (window properties such as VLT and SHGC) and import them into E-quest to run my model? It's not a perfect solution but I could have for sure a good estimate of the savings.

Within the Window, under Blinds/Drapes-Switching, there is an option for switching of window properties. This is to represent windows with electrochromic switching. As far as I know (I've never actually used it) it can only switch between two sets of window properties. But it can be switched on various ambient conditions (solar gain, temperature, etc). If thats not sophisticated enough, you could try using an 8760 hour schedule generated in Excel. Output all the data you need (OAT, solar gain, etc), then do your calculations in Excel to generate your shading schedule and import it into your file. Or if you really want a function, Doe2.1e allows them. But they're not very user friendly...

The Blinds/Drapes - Switching tab has several options that allow you to vary conductance, solar transmission, etc. during the course of a simulation. It's meant to represent variable shading, so you can decide if that's scientific enough for what you're doing. The only other "easy" way I can think of is to run the model with both (or all) of the skylight options, and stitch the results together (March through August with one, the remainder with the other for example). The effect would be the same as if a guy went up and swapped out the glass one day. You'd have to lock down equipment sizing and a few other things to make sure that's the only difference, but still easier than adding your own eQUEST feature. Maybe you're better with code than me though! Good luck however you decide to do it.

The reason why I started using it is because of its feature of managing skylight properties: for a research project I'd like to simulate an "ideal skylight" solution, which could basically adapt its main properties (VLT and SHGC) in order to minimize building energy consumption. I've seen there's a very interesting "parametric run" tool, which can make me able to perform simulations with different values of these parameters. My question is: does E-quest support the possibility of writing a function which changes this values over the run itself with a rule set by the user? Or, at least, can I set different values at different times of the day?

I run into this often as I move projects around and work on them from different locations. The .dwg file itself is never an "integral/imported" part of the project's files - only a path is defined, so eQuest will prompt you on starting up for the CAD file's location any time the project's files or the CAD file is moved around (to be expected if you're working with others on a thumb drive or similar). To re-emphasis John's point: This isn't something to lose sleep over =). The "CAD file not found" message is something you can safely ignore entirely once you are past zone/perimeter geometry definitions in the wizards. The CAD file is not actually used anywhere in eQuest beyond serving as a "reference" for the duration of those screens. Once you are finished defining zone/perimeter geometries in wizards, you can feel safe choosing "remove all" from the following dialog: [cid:image001.png at 01CD165C.FB457D50] For the duration where your group may wish to go back and revise those geometries using the CAD file, I'd advise keeping a copy of the .dwg file alongside other "reference" files to "browse" to as needed. As an organizational practice/suggestion, I commonly have a small "reference" directory that I'll save and move around alongside the actual model files containing items like this and other notes, PDF's, messages, and other electronic information I used while assembling the model.

For these simulations I've been using a very simple office model with a skylight on the top as a test-bed for my calculations (with default system for HVAC and daylighting controls with dimming for lights) but, observing the values I'm obtaining in output, I see that the values I obtain for lighting, cooling and heating consumption make sense relatively, i.e. if compared to themselves in different conditions, but are sometimes of totally different order of magnitude if compared to each other (lighting/cooling loads are often much higher than heating, by orders of magnitude), especially when scaling up the model to bigger sizes. This way, it's very difficult to see the effect of a variable change on the total energy consumption. I know the model I'm using is very idealized, but is there any variable that I can act on in order to obtain a model which has energy consumption values more similar to a real building? For example, is there a "suggested" size of the building that gives better results? Or maybe simulating a single room in a large building gives more realistic results than the single room alone? My point is that I would like to have a model whose results in scale might be consistent when applied to bigger buildings.

I've done plenty of simulation runs, which basically covered different types of buildings, of different sizes, in different locations. Of course different parameters grow with different laws, and if lighting wattage is strictly related to the building area, heating/cooling loads are influenced by the lateral surfaces and perimeter zones. This makes perfectly sense, and it was somehow what I expected to see. Said that, let me explain a little better my question: when I write about different results, I can probably show the point with an example. I take a 5x5x3m building with one skylight on the top (4% SRR) and I get certain values for lighting and HVAC loads. Then I simulate the same exact building with 50x50x6m dimensions, with 4% SRR for skylight, and I get lighting and cooling increasing by a factor of 100, heating by a factor of 10. I also have real data for this larger building, and I simulated it in Energyplus as well, and both these comparisons confirmed that heating and cooling should grow in a similar way in a temperate climate. So my question is, since I want to keep the model simple, especially on the HVAC side, which are the most important variables in Equest which might lead me to more consistent results without bringing excessive complexity into the model. Of course I'm not looking for a unique building which could be valid for all cases, but I'm caring about model consistency and validation.

The thing is that eQuest is deceptively easy, but when you want to find reliable results you basically have to find some "workaround"... The deal breaker for me in using eQuest for anything more then exploring early design options was: I had several real buildings complete with Energy Star portfolio manager data, as well as building audits, when I attempted to use eQuest discovered that eQuest was not capable of coming close to reality, in fact it wanted me to have something like zero insulation, and very poor U values to even come close. Given Energy Plus is not going to give exact results either but at least it comes close. Watch the lists, eQuest is full of "how do I come up with a work around", TRNSYS is mostly "how do I customize" and Energy Plus is mostly "how does this feature work" I do not mean to insult eQuest users but my prospective is that it makes more since to use software that is harder to use, has better support and is updated regularly for such professional and high paid work, rather then the "workaround" Why eQuest is so popular is because it is easy, but for something like your project I suggest you use Energy Plus. *Jeremiah D.

As I know, DOAS can't simulation a system with heat recovery. I made some test model before, it seems the system calculate the return air volume and temperature only include its own zone. I used single zone with reheat as the test system. But I made the test a long time ago, can't sure about it .If you want to check it , please make a simple model and check the SIM report to confirm it . Anyone else put some light on it? Thank you.

The thing is that eQuest is deceptively easy, but when you want to find reliable results you basically have to find some "workaround"... The deal breaker for me in using eQuest for anything more then exploring early design options was: I had several real buildings complete with Energy Star portfolio manager data, as well as building audits, when I attempted to use eQuest discovered that eQuest was not capable of coming close to reality, in fact it wanted me to have something like zero insulation, and very poor U values to even come close. Given Energy Plus is not going to give exact results either but at least it comes close. Watch the lists, eQuest is full of "how do I come up with a work around", TRNSYS is mostly "how do I customize" and Energy Plus is mostly "how does this feature work" I do not mean to insult eQuest users but my prospective is that it makes more since to use software that is harder to use, has better support and is updated regularly for such professional and high paid work, rather then the "workaround" Why eQuest is so popular is because it is easy, but for something like your project I suggest you use Energy Plus.

I have performed studies with similar structure as Karen is suggesting (creating and adding ?building blocks? to evaluate building massing options). However, for Stefano?s purposes I would caution to carefully take stock of what questions you are trying to answer and whether an energy model is really the way to go about finding those answers. Using an energy model to develop generic guidelines with ?arbitrary? buildings/spaces for something inherently site/climate/building-geometry-specific (such as ?ideal window wall ratio? or ?ideal window properties?) is actually a terribly complex endeavor, as I?m sure you are appreciating. You can ultimately come up with a set of guidelines/spreadsheets/principles to use, but applying such developed guidelines to an actual project for decision-making will always be fraught with accuracy disclaimers (perhaps that is not the ultimate goal ? I?m only throwing this out for consideration). Guidelines built around generic conditions are indeed useful and have their place (ASHRAE?s advanced energy design guides are worth reviewing if you?re at the outset of trying to find such results), but should only be relied upon in the context of ?I don?t want to invest in a site-specific study and the increased accuracy / differing suggestions that may produce.?

To cut myself off: I think my response drafted so far is falling away from Stefano?s original question as he?s more recently clarifying it, but I?m ultimately driving towards furthering Karen?s first line: Build project-specific models where you need a project-specific answer. To Stefano?s issue of scaling ? I am nodding my head vigorously as you?re observing how spaces modeled in isolation do not always additively represent a group of spaces modeled together. It?s possible for that to happen under certain circumstances, but the variables in play do not normally scale linearly between an isolated space and a whole building (consider the ratio of envelope surface area to conditioned volume, for one instance). A big part of ?big picture? modeling differences when compared to ?the smaller parts? is the tempering of various loads across spaces and the way that has energy saving effects on HVAC systems in particular . I would not spend too much time deliberating on such (expected) differences, and would emphasize focusing on the results of isolated or ?whole building? models as appropriate to the purpose of your study =). ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

As you mentioned, the ratio between lighting/cooling/heating changes depending on the size of the building. I'm willing to guess that this is because the core zones that have very little need for heat get much larger in relation to the perimeter zones. Also, the building energy needs will change depending on orientation and global location. I would suggest that you take a slightly different approach - try to come up with values that are representative for different types of spaces. You might do say: 1. A perimeter office space with XX% glazing (run for North, East, South and West exposures) 2. A core office space with no skylights 3. A core office space with XX% of roof area as skylights 4. A core manufacturing space??? 5,6,7.... Run each model in the applicable climate. Then, if you have an office building that is 70% core and 30% perimeter space, you'll have a better understanding of the building. This is still a very rough approximation, but should get you farther than trying to model one "typical" building. -- Karen On Mon, Apr 9, 2012 at 4:57 PM, Stefano Moret > wrote: Dear all, I've recently played around quite a bit with E-quest to simulate the effect of dynamic fenestration on building energy consumption. For these simulations I've been using a very simple office model with a skylight on the top as a test-bed for my calculations (with default system for HVAC and daylighting controls with dimming for lights) but, observing the values I'm obtaining in output, I see that the values I obtain for lighting, cooling and heating consumption make sense relatively, i.e. if compared to themselves in different conditions, but are sometimes of totally different order of magnitude if compared to each other (lighting/cooling loads are often much higher than heating, by orders of magnitude), especially when scaling up the model to bigger sizes. This way, it's very difficult to see the effect of a variable change on the total energy consumption. I know the model I'm using is very idealized, but is there any variable that I can act on in order to obtain a model which has energy consumption values more similar to a real building? For example, is there a "suggested" size of the building that gives better results? Or maybe simulating a single room in a large building gives more realistic results than the single room alone?

Yes - eQUEST is frustrating and it's a pain in the backside sometimes to try to make it do what you want it to. Maybe Energyplus is a better program to use for this. However - I don't think workarounds are necessarily a bad thing. In my experience - if you are experimenting with workarounds, it enhances your understanding of the process you are trying to model, and as a result makes you more thoughtful and allows you apply critical thinking to the process. Ultimately - most modeling is about that last item - critical thinking.

I have performed studies with similar structure as Karen is suggesting (creating and adding "building blocks" to evaluate building massing options). However, for Stefano's purposes I would caution to carefully take stock of what questions you are trying to answer and whether an energy model is really the way to go about finding those answers. Using an energy model to develop generic guidelines with "arbitrary" buildings/spaces for something inherently site/climate/building-geometry-specific (such as "ideal window wall ratio" or "ideal window properties") is actually a terribly complex endeavor, as I'm sure you are appreciating. You can ultimately come up with a set of guidelines/spreadsheets/principles to use, but applying such developed guidelines to an actual project for decision-making will always be fraught with accuracy disclaimers (perhaps that is not the ultimate goal - I'm only throwing this out for consideration). Guidelines built around generic conditions are indeed useful and have their place (ASHRAE's advanced energy design guides are worth reviewing if you're at the outset of trying to find such results), but should only be relied upon in the context of "I don't want to invest in a site-specific study and the increased accuracy / differing suggestions that may produce." Evaluating how well any study applies to the project-at-hand is something to always keep in mind. To cut myself off: I think my response drafted so far is falling away from Stefano's original question as he's more recently clarifying it, but I'm ultimately driving towards furthering Karen's first line: Build project-specific models where you need a project-specific answer. To Stefano's issue of scaling - I am nodding my head vigorously as you're observing how spaces modeled in isolation do not always additively represent a group of spaces modeled together. It's possible for that to happen under certain circumstances, but the variables in play do not normally scale linearly between an isolated space and a whole building (consider the ratio of envelope surface area to conditioned volume, for one instance). A big part of "big picture" modeling differences when compared to "the smaller parts" is the tempering of various loads across spaces and the way that has energy saving effects on HVAC systems in particular . I would not spend too much time deliberating on such (expected) differences, and would emphasize focusing on the results of isolated or "whole building" models as appropriate to the purpose of your study =). ~Nick NICK CATON, P.E.

As you mentioned, the ratio between lighting/cooling/heating changes depending on the size of the building. I'm willing to guess that this is because the core zones that have very little need for heat get much larger in relation to the perimeter zones. Also, the building energy needs will change depending on orientation and global location. I would suggest that you take a slightly different approach - try to come up with values that are representative for different types of spaces. You might do say: 1. A perimeter office space with XX% glazing (run for North, East, South and West exposures) 2. A core office space with no skylights 3. A core office space with XX% of roof area as skylights 4. A core manufacturing space??? 5,6,7.... Run each model in the applicable climate. Then, if you have an office building that is 70% core and 30% perimeter space, you'll have a better understanding of the building. This is still a very rough approximation, but should get you farther than trying to model one "typical" building. -- Karen On Mon, Apr 9, 2012 at 4:57 PM, Stefano Moret > wrote: Dear all, I've recently played around quite a bit with E-quest to simulate the effect of dynamic fenestration on building energy consumption.

Also, the building energy needs will change depending on orientation and global location. I would suggest that you take a slightly different approach - try to come up with values that are representative for different types of spaces. You might do say: 1. A perimeter office space with XX% glazing (run for North, East, South and West exposures) 2. A core office space with no skylights 3. A core office space with XX% of roof area as skylights 4. A core manufacturing space??? 5,6,7.... Run each model in the applicable climate.

On second thought a better way to scale would he to maintain the ratio of length x width / height x ((2 x length) + (2 x width)) If height is constant then a 10x10 space scaled up ten times floor area would best scale to something like 194x5.1 (excuse calculations, no calculator doing this at red lights). Where other issues arise like the exposure of the long face will make a big impact. If building modeling could be scaled for certain constants this easily them we could do it with little paper wheels like ductulators. Fun to think about though!

data from a vendor. Also, I don't think there is a development team anymore, they all work on E+ now. I was just looking at this today, I had a job with scroll chillers. Just at a glance I noticed the EIR =f(PLR) curve is a lot more linear than the screw chiller curve. The limited part load data I had for my chiller seemed to suggest it was a lot more non linear. So your mileage may vary. Also make sure that you normalize any curves that you use to your design EIR. The default curve is EIR2(1) = .1305 . Elechour = Caphour * EIR * EIR1f(t1,t2) * EIR2f(PLR) / 3413 Btu/kW So if you don't normalize it is going to think it's using a fraction of the energy that it should be.

I'm guessing the "screw" chiller type is the closest option. Out of curiosity, I searched the library and found the following performance curves: ScrollChlrAirCoolEIR-fPLR ScrollChlrAirCoolEIR-fCHW&OAT ScrollChlrAirCoolCap-fCHW&OAT Using these curves greatly reduced (by 33%) the cooling energy vs. the default ScrewAir-EIR and ScrewAir-Cap curves. Did I find the eQUEST version of a video game cheat code? (Any reason I shouldn't use these ScrollChlr curves?)

You didn't describe how many unmet hours you have or what you have tried already. Unmet heating hours can result from underheating, but also from overcooling. Depending on what you change in the model, you might end up increasing your heating energy, or you can end up reducing both cooling and heating energy. Here are a few things to try: ? Enter a value for the system REHEAT-DELTA-T. Leaving this blank can result in thousands of unmet heating hours. ? Set the system COOL-CONTROL to something other than CONSTANT, provided the system you are modeling has the controls capability. I have had success with WARMEST and RESET. ? If you change COOL-CONTROL to COLDEST or WARMEST, increase the zone THROTTLING-RANGE from the default 2?R (2?F). 4?-6? is recommended. You can start with 3? and increase by 0.5? to see how the unmet hours change. If you are comparing two models or two system types, keep the same throttling range in both models to make it a fair comparison. ? Adjust air flow rates, such as your system and/or zonal MIN-FLOW-RATIO. Search the archives here: http://lists.onebuilding.org/pipermail/equest-users-onebuilding.org/ You could always post your .inp and .pd2 files and someone might look at your model.

I assume you're in the context of lights. What's appropriate depends on how you have set up your model and to what degree their operation needs to be modeled explicitly. A few approaches, from simple to involved: * Established 90.1 Appendix G approach: Assign a flat % reduction to the installed LPD for the space(s) with occ sensors (only in those that don't already require them, if you're actually doing a proposed/baseline performance rating). * Define alternate fractional schedules that represent hourly operation of lights with and without occ sensors. This can be approached with a few variations to achieve the same result. Some choose to apply a % reduction to the schedules instead of the installed watts per space, achieving an identical result. * Redefine space occupancy schedules in a manner that makes them appropriate to assign to the lighting loads as well (i.e. setting 1.0 for occupied hours), and use the same schedules for both occupancy and lighting - if accuracy is critical, you'll want to consider moving away from a "whole building" fractional schedule as generated by the wizards and move towards "per space type" scheduling. In this scenario the hourly occupancy value is multiplied against the installed Watts for each space, so you could correctly account for an occ. sensor's time delay into an unoccupied hour with a fractional value. More creative (and potentially convoluted) solutions are out there that might fit your model on a case-by-case basis, but the three above are approaches I've used more than once. ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

There is no computer program which with the press of a button will design your building for you. You have unmet hours because you have conflicts in your design. You now have to identify the conflicts and resolve them. eQuest works by prioritizing the cooling system, hence when you have conflicts they show up mostly as unheated hours. eQuest has a low default on airflow, 0.5 cfm/SF, this many times is a good place to start. Depending on where you are 0.75 or 1.0 could work better. You can also vary the flow to different zones independently. You can't put 0.5 cfm into 20 spaces from the same AHU and expect the heating and cooling needs of each space to be met 100% of the time. Get into your sim file and figure out where the spaces are with large unmet hours, figure out why and start adjusting the inputs to reduce them. There is no point to average the 4 orientations, nor is it allowed, just LEED mumbo jumbo. It just illustrates how the orientation of your building effects the energy consumption to run it. Most modellers get a building, a street, a front and back with no option on orientation. That is your base case. It can be handy to illustrate design flaws if there is a large difference in energy consumption in different directions.

Set up your first building (ideally as a single shell), then create new shells by copying the first - editing the rotation and internal layout as necessary. If/when you have everything set up, you can save multiple copies of the file and remove the shells you don't want for each case to isolate to the correct building. You shouldn't need re-enter the same information twice. To something Yusuf mentioned earlier: Modeling the savings of solar street/landscape lighting can be re-stated as determining the energy consumption of a "non-solar equivalent." This is a lot trickier than it may seem on the surface. Much of that complexity is tied up in what "non-solar equivalent" means in reality: Dig hard at the cutsheets of the solar equipment in question to come up with some hard numbers for photometrics and runtime realities. If you are not trained/familiar with photometric lighting design software you may want to engage someone who is to help you along the way. [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

Sounds like the only thing for you to nail down is operating hours of the solar lights. Regarding the DD wizard... I'm suggesting starting with one file then later splitting into multiple files, as you suggested for use with an external spreadsheet, to appropriately multiply the results without a massive model of the entire campus. Here is a quick illustration: [cid:image002.png at 01CD17F4.C52FDDC0] After completely finishing "Building A," defined as a single shell, click "create new shell" and choose to copy "Building A." You can then make only the necessary edits to orientation, space layout, window layout, etc... and other inputs will be repeated from the copied shell. Repeat that procedure for as many unique buildings as you require, then when finished you can proceed with saving the project a few times and in each project removing the shells you do not need to isolate to one building. Hope that helps get my suggestion across better! ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

Set up your first building (ideally as a single shell), then create new shells by copying the first - editing the rotation and internal layout as necessary. If/when you have everything set up, you can save multiple copies of the file and remove the shells you don't want for each case to isolate to the correct building. You shouldn't need re-enter the same information twice. To something Yusuf mentioned earlier: Modeling the savings of solar street/landscape lighting can be re-stated as determining the energy consumption of a "non-solar equivalent." This is a lot trickier than it may seem on the surface. Much of that complexity is tied up in what "non-solar equivalent" means in reality: Dig hard at the cutsheets of the solar equipment in question to come up with some hard numbers for photometrics and runtime realities. If you are not trained/familiar with photometric lighting design software you may want to engage someone who is to help you along the way. [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

I guess I have someway to go before I have system sizing and unmet hours fully figured out. One more question: * If I want to create multiple buildings of similar type, built up area and construction but different conditioned spaces, interior layouts and orientations. Can I simply make a copy of the old pd2 file and simply change the footprint zone and orientation in the new file? I tried to do this but I cannot see the 3D model of the new building. Does this mean every model has to be created from scratch? Many Thanks Yusuf On 11 April 2012 19:03, Bruce Easterbrook > wrote: Auto sizing is to ball park your system. There is no computer program which with the press of a button will design your building for you. You have unmet hours because you have conflicts in your design. You now have to identify the conflicts and resolve them. eQuest works by prioritizing the cooling system, hence when you have conflicts they show up mostly as unheated hours. eQuest has a low default on airflow, 0.5 cfm/SF, this many times is a good place to start. Depending on where you are 0.75 or 1.0 could work better. You can also vary the flow to different zones independently. You can't put 0.5 cfm into 20 spaces from the same AHU and expect the heating and cooling needs of each space to be met 100% of the time. Get into your sim file and figure out where the spaces are with large unmet hours, figure out why and start adjusting the inputs to reduce them. There is no point to average the 4 orientations, nor is it allowed, just LEED mumbo jumbo. It just illustrates how the orientation of your building effects the energy consumption to run it. Most modellers get a building, a street, a front and back with no option on orientation. That is your base case. It can be handy to illustrate design flaws if there is a large difference in energy consumption in different directions. Just don't call it that when you are telling the architect a 20 story atrium is not a great idea on the north side of a building. lol. Bruce Easterbrook P.Eng.

However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis.

This approach makes approximations of the radiant component of heat transfer and does not directly calculate radiant gains or losses. Because of this, any DOE2 based software at best can predict air temperature and moisture needed for a PMV calc. EnergyPlus or IES are the only engines that can produce hourly surface temp information and therefore, mean radiant temperature averages. If you are interested in providing comfort feedback of envelope changes and not HVAC changes, learning EnergyPlus using OpenStudio from NREL is well worth the time and effort. Their workflow takes some practice to adopt but once you get the hang of things, creating buildings is very easy. Their youtube channel is best for explaining this, search for OpenStudio and NREL.

It uses Weighting Factors (also known as Room Response Factors) that characterize the dynamic response of a space for a given input of heat flow. Envelope heat flows are similarly calculated using Response Factors that are also dynamic, i.e., they capture the thermal lag and capacitance of the materials. Radiant heat gains are taken into account in both response factors (using the sol-air temperature method) and weighting factors (there are different weighting factors for different types of heat gain). However, radiant heat gains are ignored in interzone heat transfer. Although DOE-2 doesn't compute inside surface temperatures, they can be output (in DOE-2.1E at least) and I've that little-known feature to do PMV calculations. Lastly, DOE-2 has always been able to model the humidity of the indoor air. What it doesn't do (which may be what you're thinking) is that it doesn't model the absorption/desorption of moisture in the building fabric.

Or the rule set might be failing because it doesn't know the ASHRAE climate region for your location (Mumbai). I assume that you have a weather file for Mumbai. I recently created last year a set of weather files for 38 Indian locations for ISHRAE, so if you have any problems there, just give me a holler. However, even if you get these practical problems resolved, I question the logic of creating an ASHRAE-90 building as the reference or comparison building for your study, which would set all the building conditions to ASHRAE-90 requirements. I would recommend that, instead, you create a reference building based on India's ECBC, or if you don't think that's being widely followed yet, on what you think are the typical construction and operating conditions in Mumbai. I can also think of several friends in India, even Mumbai, that I could recommend if you need help. It seems that you're thinking of modeling a green roof as an additional soil layer. That's okay for starters, but if that's the topic of your thesis, you should do a more careful job and incorporate the following characteristics that makes a green roof differ from just 20 cm of dirt on top: (1) changing soil moisture depending on the time of year and rainfall, and (2) evaporatranspiration that would keep the soil surface temperature low on sunny days. This is not a marketing pitch, but in DOE-2.1E (an earlier version of the DOE-2.2 engine in eQUEST) that I still use, there is a feature called "Functions" that would allow users to insert additional code in pseudo-Fortran to model processes not covered by the program. If you're interested, we can discuss more offline. Again, this is not a marketing pitch.

If you shut off your dehumidification limit of 50%, it eliminates the summer heating issue. Also, I don?t know how much control you have over your economizer settings, but if you haven?t read this article , I?d strongly suggest it. As an interesting aside ? that author?s comments on RH sensor reliability matches well with what I?ve found on a recent project. Here?s a little data I?ve gathered from a college campus. I harvested 24hr trend data from all the buildings that were measuring OA humidity (y-axis in %). The fat blue line is what I got from the National Weather Service for the area and each other line represents a building?s OA humidity sensor. I think in total these sensors control at least 25 AHU?s enthalpy economizers. From what I can tell, they don?t have a regular PM routine for calibrating/replacing these sensors. Just something to consider?

It might be useful in Loads program based on design day conditions in summer and winter. See http://bepan.info/engg-calcs - 3a - Design-Weather-Generator DOE2.1E uses the Transfer Function method to calculate envelope heat transfer. I think Trane-TRACE and Carrier-HAP use the same method. The CLTD-SCL-CLF method is still very useful for teaching envelope heat transfer. See http://bepan.info/class-notes/e4-project-loads The Total Equivalent Temperature Difference (TETD) method is also useful for teaching. See - http://bepan.info/hvac-prog/x1-apec-hccv-loads It is difficult to explain the heat storage capacity and time lag concepts of the envelope with the other methods although all Loads calculations are done by computer today. The APEC (Automated Procedure for Engineering Consultants) HCC-V Loads program can be downloaded and used. If you don?t know what the ?decrement factor? is, use 0.5 since the range is between 0 and 1. An estimate for ?time-lag? depends on the type of bldg. In design loads calculation for commercial buildings it is important NOT to underestimate the loads. The hourly Fortran Variable report of the DOE2 based programs include outside wall surface temp. In the DOE2 Loads section choose (1) Variable-Type = u-name of EXTERIOR-WALL (2) Variable List Number 5 Q Heat transfer from wall to the zone un-weighted (Btu/hr) (3) Variable List Number 6 T Outside surface temperature (Rankine). Transfer the values of Q and T to an Excel spreadsheet and calculate the inside wall surface temps.

URL: -------------- next part -------------- Alex you are correct, eQuest does not know the surface temperatures required to calculate the Mean Radiant Temperature. eQuest /DOE2 uses the Cooling Load Temperature Difference (CLTD) method to arrive at heat loads in a space. This approach makes approximations of the radiant component of heat transfer and does not directly calculate radiant gains or losses. Because of this, any DOE2 based software at best can predict air temperature and moisture needed for a PMV calc. EnergyPlus or IES are the only engines that can produce hourly surface temp information and therefore, mean radiant temperature averages. If you are interested in providing comfort feedback of envelope changes and not HVAC changes, learning EnergyPlus using OpenStudio from NREL is well worth the time and effort. Their workflow takes some practice to adopt but once you get the hang of things, creating buildings is very easy. Their youtube channel is best for explaining this, search for OpenStudio and NREL.

I'll second the suggestion to purchase the Thermal Comfort tool. It is easy to use. I believe that a newer version was recently released - we're still using the 1994 version. However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis. I included Jeremiah's response below which suggests that Energy Plus can do these calculations. This was my impression, however I have never used E+ to do them.

See http://www.whiteboxtechnologies.com/ Click here for the Open Letter to Lawrence Berkeley National Lab (LBNL) on Open Source DOE-2.1E.) DOE2.1E is particularly suited for academic thesis research for the following reasons: 1. It is a mature computer program that has been in extensive use for nearly 30 years. In fact, its latest proprietary version (DOE-2.2/eQUEST) is clearly the most widely used building energy simulation program in the US, if not the entire world. 2. Compared to other simulation programs, DOE-2 runs very quickly. 3. Since DOE-2.1E has been in effect abandoned by DOE and LBNL, its code can be made open source, and be freely available to students and researchers 4. DOE-2.1E contains a User Function option that allows users to develop additional modules or tweak existing calculations without having to change and recompile the existing source code. User Functions are ideal for student applications. Those that are promising can then later be incorporated into the source code itself. Here are suggestions of how to fix DOE-2.1E so that it can be used for academic thesis research 1. Provide better documentation and examples of building models and User Functions. 2. Develop teaching materials on how to use the DOE-2 program, including how to extract hourly data, use macros to manage sensitivity analyses, and available open-source user interfaces. 3. Freeze the existing code since it is error-free and make it possible for research students to add/attach independent sub programs to expand the features of DOE-2.1E. The independent (or dependent) sub-programs that can be interfaced with DOE-2.1E should include PV-modules, GSHP, UFAD, DOAS, Radiant-ceilings and other features not included in DOE-2.1E. There could be multiple versions of each sub-program by different authors. 4. A DOE-2.1E committee should establish common output reports for them. You can expect advanced program development using an open source DOE2.1E as the base launching pad from enterprising architects, engineers, academics in the areas renewable energy and also in testing new concepts. The analogy is countries like socialist India and communist Russia & China opening up development to individual free enterprise. All the economies are now booming after 15 years. Their economies stagnated during the previous 50 years of the government doing everything. Trane & Carrier have their own energy programs (TRACE and HAP) based on their equipment and systems. Other manufacturers can now create energy programs starting with the open source DOE2.1E and base it on their own equipment. These would be program developers that are involved with real buildings from design through construction and operation and understand the business. Equipment consumes energy in buildings, not the envelope or people. Manufacturers would therefore have vested interest in making sure that their energy programs produced results that are close to the building in operation. ----- Original Message ----- From: Joe Huang Date: Sunday, April 15, 2012 2:15 pm Subject: Re: [Equest-users] Urgent request > Sharma, > > eQUEST is a program developed in the US, so its compliance rule > set > might not work for locations outside of the US. > Or the rule set might be failing because it doesn't know the > ASHRAE > climate region for your location (Mumbai). etc > This is not a marketing pitch, but in DOE-2.1E (an earlier version > of > the DOE-2.2 engine in eQUEST) that I still use, there > is a feature called "Functions" that would allow users to insert > additional code in pseudo-Fortran to model processes > not covered by the program.

I have not been in great detail through your model, but I saw right away that you have specified humidity control on your packaged unit, with a 50 percent maximum. I believe that your cooling system will be running in the summer for dehumidification quite often when the space temperature is already satisfied. The electric heat will have to come on to re-heat the air. This will show as a load on the heating coil. Hope this helps! If not, I look forward to hearing what's causing your summertime heating.

Here's a puzzle for the email group. (I hope you're having a better weekend than me!) I've searched the archived emails to find a solution, but most seem to ask for the PD2 and INP file so that makes me think that the solutions will mostly be unique. I'm attaching a zip file of my model. I have packaged single zone units with electric resistence heat. I'm seeing a significant load in the summer on all units. I've dropped the thermostat in the summer months on the heating and am still getting a load. Any ideas on why there would be a load?

I finally found what I was looking for, and it looks like this has been the goal of a DOE project concluded in 2008. In the website I linked below, there are listed some models of commercial building prototypes which have demonstrated to fit most of the commercial buildings in the US, and which could serve as a starting point for modeling energy efficiency measures without the risk of having results dependent on the specific modeling assumptions, of course within reasonable ranges. There are also the IDF files which serve as input for E+. To recall the elephant and the mouse metaphor, here there?s probably a good reference for consistent mice and elephants prototypes, and that was exactly what I was looking for. Here?s the website for your interest: http://www1.eere.energy.gov/buildings/commercial_initiative/reference_buildings.html Thanks again for your hints, and best regards Stefano -- Stefano Moret California Lighting Technology Center University of California, Davis 633 Pena Drive Davis, CA 95618 530-747-3846 smoret at ucdavis.edu From: equest-users-bounces at lists.onebuilding.org [mailto:equest-users-bounces at lists.onebuilding.org] On Behalf Of joe at thespinnakergroupinc.com Sent: Tuesday, April 10, 2012 11:06 AM To: joe at thespinnakergroupinc.com; Shaun Martin; equest-users at lists.onebuilding.org Subject: Re: [Equest-users] Scale modeling And of course note you have multiple floors to deal with when you scale up... On second thought a better way to scale would he to maintain the ratio of length x width / height x ((2 x length) + (2 x width)) If height is constant then a 10x10 space scaled up ten times floor area would best scale to something like 194x5.1 (excuse calculations, no calculator doing this at red lights). Where other issues arise like the exposure of the long face will make a big impact. If building modeling could be scaled for certain constants this easily them we could do it with little paper wheels like ductulators. Fun to think about though!

Otherwise, as has been mentioned in the previous emails, the ratio of envelope surface area to floor plan area will change. A 10x10x10 building, (heat/cool load-wise), will scale better to a 100x100x100 then it would to a 100x100x10, because the ratio of floor space to envelope area is maintained. Although only the top floor will have roof load. And a skylight will only effect the top floor of the larger scale building. Can you change from a skylight to a window with daylighting? This would scale better.

The results likely represent some sort of curve, and are probably multivariate. My suggestion would be to model large, medium and small scenarios and do hourly reports of the loads to see what is happening at different outside temperatures.

An elephant eats about 5% of their own body weight in food daily. The surface area to mass ratios are vastly different. Heat loss, metabolism (internal loads) and fur are very different. If an elephant had the fur of a mouse it would die from overheating. You can't model a small building and try to extrapolate the results to a large building.

As you mentioned, the ratio between lighting/cooling/heating changes depending on the size of the building. I'm willing to guess that this is because the core zones that have very little need for heat get much larger in relation to the perimeter zones. Also, the building energy needs will change depending on orientation and global location. I would suggest that you take a slightly different approach - try to come up with values that are representative for different types of spaces. You might do say: 1. A perimeter office space with XX% glazing (run for North, East, South and West exposures) 2. A core office space with no skylights 3. A core office space with XX% of roof area as skylights 4. A core manufacturing space??? 5,6,7.... Run each model in the applicable climate. Then, if you have an office building that is 70% core and 30% perimeter space, you'll have a better understanding of the building. This is still a very rough approximation, but should get you farther than trying to model one "typical" building. -- Karen On Mon, Apr 9, 2012 at 4:57 PM, Stefano Moret > wrote: Dear all, I've recently played around quite a bit with E-quest to simulate the effect of dynamic fenestration on building energy consumption. For these simulations I've been using a very simple office model with a skylight on the top as a test-bed for my calculations (with default system for HVAC and daylighting controls with dimming for lights) but, observing the values I'm obtaining in output, I see that the values I obtain for lighting, cooling and heating consumption make sense relatively, i.e. if compared to themselves in different conditions, but are sometimes of totally different order of magnitude if compared to each other (lighting/cooling loads are often much higher than heating, by orders of magnitude), especially when scaling up the model to bigger sizes. This way, it's very difficult to see the effect of a variable change on the total energy consumption. I know the model I'm using is very idealized, but is there any variable that I can act on in order to obtain a model which has energy consumption values more similar to a real building? For example, is there a "suggested" size of the building that gives better results? Or maybe simulating a single room in a large building gives more realistic results than the single room alone? My point is that I would like to have a model whose results in scale might be consistent when applied to bigger buildings.

It is not conflict. For you case, could the hospital floors can be considered as residential area? you should check it.

Table G3.1.1A in Appendix G is used to decide the baseline HVAC as shown below [cid:image001.png at 01CD1CAE.51567440][cid:image002.jpg at 01CD1CAE.51567440] The note under the table which i have underline say "Where attributes make a building eligible for more than one baseline system type, use the predominant condition to determine the system type for the entire building." It seems that only one HVAC system will be used in baseline. However, in ASHRAE 90.1-2007 User's Manual , there is no explaination about the note. While the Case Study in Page G-37 of User's Manual tell us that two different types of HVAC system should be usedrespectively forthe Residential part and office part as shown below.So I think this conflict with the ASHRAE90.1-2007 StandardTable G3.1.1A. what about your views? [cid:image001.png at 01CD1CAE.51567440][cid:image003.jpg at 01CD1CAE.51567440] If a hospital building includes mainly wards in 3~7 floors with an area of 132000ft2 and therapy zone in 1~2 floors with an area of 52000ft2, the proposed building is FCU served by chiller and boiler, I tend to the PTAC system (system 1) for 3~7 floors and system 5 for 1~2 floors. what about your opinion? Thank you for any comments and directions.

As an industry we are very in the dark about reasonable/typical infiltration rates. I suspect any model reviewer, GBCI or otherwise would have a difficult time assessing if the claimed savings due to improved air barrier, or whatever strategy is implemented, are reasonable, especially given that there is no clear baseline established by 90.1. However, you could always put forward a well reasoned argument with back up data and studies and it is possible that the reviewer will allow you take credit. Cite some reputable sources. Submit it as an Exceptional Calculation Methodology with the claimed savings separated out from the rest of your model so it can be discretely evaluated. Here is Seattle the city is requiring new projects to conduct full building air leakage testing prior to occupancy with the city receiving the results as part of a data collection effort, presumably so that they can set reasonable requirements for air leakage in the future. Maybe this data can work its way into an upcoming 90.1 cycle and we can all have a more reasonable approach for modeling air leakage.

What you functionally lose along the way is the ability to assign a shading schedule or otherwise alter the opacity of the resulting "shade." Disclaimer: Defining shades with exterior wall sections is likely going to be time consuming, however you slice it. Like anything worth doing, right =)? If you're interested in pursuing this, you should first consider whether the shade you're emulating can be represented/approximated in 2D. I did a writeup once (full discussion attached) showing how one can apply the concept above to represent a complex, repeating shape to pick up the shading of a superstructure. Here's an illustration showing the end-result: [cid:image005.png at 01CB5978.13595400] To up the ante, with another tier of effort you can approach approximating 3D shapes with polygonal exterior wall sections... but I would sooner advise strongly considering whether a 2D equivalent can be defined, or if you might better invest your time learning a more complex-geometry-compliant energy modeling software (I keep meaning to do this!). Following is a visual of using polygonal exterior wall sections as shades to achieve a 3D shape - this was not a small amount of work: [cid:image002.png at 01CD1CAC.4CC51730] A couple folks have, in years past, developed impressive looking export tools (from the likes of sketchup, revit and so forth) that at least appear to automate production of polygons for complex geometries in eQuest...

What you functionally lose along the way is the ability to assign a shading schedule or otherwise alter the opacity of the resulting "shade." Disclaimer: Defining shades with exterior wall sections is likely going to be time consuming, however you slice it. Like anything worth doing, right =)? If you're interested in pursuing this, you should first consider whether the shade you're emulating can be represented/approximated in 2D. I did a writeup once (full discussion attached) showing how one can apply the concept above to represent a complex, repeating shape to pick up the shading of a superstructure. Here's an illustration showing the end-result: [cid:image005.png at 01CB5978.13595400] To up the ante, with another tier of effort you can approach approximating 3D shapes with polygonal exterior wall sections... but I would sooner advise strongly considering whether a 2D equivalent can be defined, or if you might better invest your time learning a more complex-geometry-compliant energy modeling software (I keep meaning to do this!). Following is a visual of using polygonal exterior wall sections as shades to achieve a 3D shape - this was not a small amount of work: [cid:image004.png at 01CD1CC2.1BBE9380] A couple folks have, in years past, developed impressive looking export tools (from the likes of sketchup, revit and so forth) that at least appear to automate production of polygons for complex geometries in eQuest... I've never seen any of these freely distributed nor test-driven any such tool/process myself, so I can't endorse further other than to note they're out there and might be available, for a cost.

In China the grading standard of curtain wall air tightness is under 10 delta pressure. The 2.0L/s m2(75Pa) is equal to 0.522L/Sm2(10[a) which is much worse than China GB standard(0.278L/sm2, 10pa) However in other sections like chiller cop or lighting Power ASHRAE standard are much more strict than China GB code.

As an industry we are very in the dark about reasonable/typical infiltration rates. I suspect any model reviewer, GBCI or otherwise would have a difficult time assessing if the claimed savings due to improved air barrier, or whatever strategy is implemented, are reasonable, especially given that there is no clear baseline established by 90.1. However, you could always put forward a well reasoned argument with back up data and studies and it is possible that the reviewer will allow you take credit. Cite some reputable sources. Submit it as an Exceptional Calculation Methodology with the claimed savings separated out from the rest of your model so it can be discretely evaluated. Here is Seattle the city is requiring new projects to conduct full building air leakage testing prior to occupancy with the city receiving the results as part of a data collection effort, presumably so that they can set reasonable requirements for air leakage in the future. Maybe this data can work its way into an upcoming 90.1 cycle and we can all have a more reasonable approach for modeling air leakage.

The APEC (Automated Procedure for Engineering Consultants) HCC-V Loads program can be downloaded and used. If you don?t know what the ?decrement factor? is, use 0.5 since the range is between 0 and 1. An estimate for ?time-lag? depends on the type of bldg. In design loads calculation for commercial buildings it is important NOT to underestimate the loads. The hourly Fortran Variable report of the DOE2 based programs include outside wall surface temp. In the DOE2 Loads section choose (1) Variable-Type = u-name of EXTERIOR-WALL (2) Variable List Number 5 Q Heat transfer from wall to the zone un-weighted (Btu/hr) (3) Variable List Number 6 T Outside surface temperature (Rankine).

URL: -------------- next part -------------- Alex you are correct, eQuest does not know the surface temperatures required to calculate the Mean Radiant Temperature. eQuest /DOE2 uses the Cooling Load Temperature Difference (CLTD) method to arrive at heat loads in a space. This approach makes approximations of the radiant component of heat transfer and does not directly calculate radiant gains or losses. Because of this, any DOE2 based software at best can predict air temperature and moisture needed for a PMV calc. EnergyPlus or IES are the only engines that can produce hourly surface temp information and therefore, mean radiant temperature averages. If you are interested in providing comfort feedback of envelope changes and not HVAC changes, learning EnergyPlus using OpenStudio from NREL is well worth the time and effort. Their workflow takes some practice to adopt but once you get the hang of things, creating buildings is very easy. Their youtube channel is best for explaining this, search for OpenStudio and NREL.

I'll second the suggestion to purchase the Thermal Comfort tool. It is easy to use. I believe that a newer version was recently released - we're still using the 1994 version. However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis. I included Jeremiah's response below which suggests that Energy Plus can do these calculations. This was my impression, however I have never used E+ to do them.

Only when this kind of heating is not sufficient for loads will the fans in the convector units start working. This will be controlled by an outside air thermostat. Which system would be the most suitable for this in eQuest and how to tell the software that fans will only be operational below a certain temperature (FYI: cooling in the same spaces will be by VRF units).

A Loads program should show the temps in the rooms that have no thermostat. The SOM-IBM-AES loads program developed in the late 1980s (and died in the early 1990s) did have this feature. See - http://bepan.info/hvac-prog/x2-som-ibm-aes-hvac I think the TRACE program has a room level but I am not sure it calculates the temp in the rooms without a thermostat. If it does, then provide no HVAC to a room without a thermostat to get the resulting temp. But then such rooms would have windows open in summer. -------------- next part -------------- An HTML attachment was scrubbed...

Hope this Helps! "You can tell eQUEST to run multiple Design Days by setting the start day and the number of days in the Design Day Properties dialog box in the detailed interface (don't know about the wizard). For example I normally set the start day to 6/1 and the number of days to 120. That way it will cover all the solar angles from June - September combined with the ASHRAE Cooling DB / WB, and will use the heating/cooling design day schedules specified in the Week Schedules. I figure this should pretty much cover it, although as Carol said there is usually a peak in the weather file that exceeds the ASHRAE conditions." ( http://lists.onebuilding.org/pipermail/equest-users-onebuilding.org/2008-September/000365.html) Before equest will use the Design Day information in the schedules you need to setup actual design days for the simulation to use. You need to do this in the *detailed edit under the Project & Site tab*. You need to create both a heating and cooling design day and then input the desired temperature extremes and duration that you wish to simulate. Reference the climate design data in the ASHRAE Fundamentals Handbook for your location. Once you create the design days equest will use them for equipment sizing rather than the peak heating & cooling loads calculated from the TMY weather data.

If your primary goal is to compare the relative performance of two systems on the same building, then you can rest assured you've made fine decisions so far. That you're simultaneously tasked with "validating" one choice over another might complicate things in presentation of your results - it depends on how the cookies crumble. More later. eQuest is a capable tool to this end, but I might have cautioned you at the outset that eQuest can quickly become unwieldy for "a simple comparison" when trying to compare certain system types, especially for newer/intermediate users. That said, you are clearly well-invested into this model, and why would anyone want to miss a learning opportunity, right =)? General rule: A more representative model will always produce a 'better' result - the corollary is that 'better' is not always what you're hoping for. "Degree-of-accuracy" is always a balancing act for any model - it's clear you're taking an active role in deciding when/how to improve the model's degree of detail, however. That's enough to satisfy me. So long as you personally feel the model is "representative enough," that's the key litmus test when you're the one presenting the results ;). I would not suggest stopping and building a 90.1 baseline model provided with this extra context, but you could use 90.1 as a broader reference to ensure you are making a fair comparison. For example, 90.1 Appendix G has a section discussing unmet hours and establishes a threshold for both the (90.1) baseline and proposed models. Have you made a similar check between your chiller and DX models to ensure they're on similar footing? I almost always build my models from DD wizards instead of SD so my usual workflow may produce different "normal fixes," but I commonly need to spend extra time reviewing the hydronic inputs in detailed mode to ensure any chiller system is being correctly modeled. Give your chiller, pump, and loop inputs a good scour, particularly pump operation/scheduling inputs. You mentioned also changing the quantity of airside systems for the DX model - it might be worthwhile to review the schedules applicable to the consolidated system to ensure its operating as a single large AHU would. When all is said and done if you still feel uncomfortable with your inputs, I've often found it productive to have the responsible mechanical designer scan through typical waterside/airside inputs alongside me to identify anything that appears off. I have found pulling other designers in is a good QC practice for all skill levels where the modeler didn't do all the work him/herself. I find it easiest to plan on missing some nuances along the way (Murphy's law), and allow those most intimate with the design to collaborate with me to pick any loose threads up. So full-circle... regarding your 'intended' results: Accept that the "right" answer can ultimately swing either way. Whenever performing a comparative study, keep in mind all such results are built on unknowns/assumptions. Where the results are close, it's not uncommon to conclude there are multiple right answers. ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

The geometry and building envelope are not exact, but I made this decision because we are doing this for comparison purposes, so the geometry and construction will be the same. I have let eQuest autosize both systems. Sincerely, Matt Clough -------------- next part -------------- An HTML attachment was scrubbed...

What is the best way to go about verifying this? In the 'Hourly Report Block' options under a system, I find 'Hourly summed zone OA CFM for DCV calculation (cfm)' and 'Hourly max zone OA/total flow for DCV calculation (cfm/cf/). Is one or both of these options under an hourly report, the way to go or is there a better way of doing it? Thanks, Ramana. -------------- next part -------------- An HTML attachment was scrubbed...

The part-load performance of the system could also be important if the hours for the shop and show room are different ? this could be a case where two or more right-sized DX systems may be a better match than one chiller, depending on the magnitude for the loads and if the zones have wildly different hours of operation. My suggestion would be to set eQUEST aside for a half hour, and just run through a table for the fan power, pump power, and cooling efficiency for each of the two cases and see if the answer jumps out at you. If you get pointed strongly in one direction, then review the eQuest files more closely to be sure you are capturing all of the part-load effects.

So the program outputs 2 sim files ? the base(proposed, CHW) case and the iterated (DX) case We want to use eQuest to validate the system choice on this particular project. This is work that was started before I joined, but I have been selected to try and use eQuest to compare the performance of a chilled water system and a DX system. I?m not the most experienced energy modeler, but it seems like a task that would be a good application for eQuest. My approach was to simulate the energy consumption of a building that is similar to the actual design in orientation, shape, and square footage. I initially built the model in the SD wizard, using most of the default values (building envelope, activity usage, etc.), autosize the equipment, and use the EEM to compare the two systems. The idea was that when the building construction and geometry are equal, we can look at the relative energy consumption of the two systems. This initial simulation reported that the DX system would be more efficient, which is not what I had expected based on the design that had been selected. So I figured that maybe my model was too generic, too simple. I created zones based on the plans, and made the geometry more representative of the actual building. These changes produced reports that suggest the chilled water system is more efficient than the DX. I realized that the EEM was incorrectly modeling the change ? it was treating the chilled water system as having all 8 air handlers, but was modeling the DX system as one AHU. So I created a duplicate model that has a DX system (autosized and using equest defaults). The comparison of these two models suggests the DX system is slightly more efficient. Unfortunately, my lack of experience makes me doubt the validity of this comparison ? especially considering that the engineers selected a chilled water system for this project. So I suppose my questions are: Does my approach seem valid? Is this an appropriate use of the software? After taking some time to write this note, and with a little rest, I wonder if comparing the proposed design to an ASHRAE 90.1 baseline would have been a better approach.

From the energy breakdown contrast, what surprises me is that the energy for cooling is more than before. When I try to change the fan delta t from 0.93 to 0 and find the cooling energy is decreasing than inputting the whole EER, but the sum of cooling and fan is still more than inputting the whole EER , have anyone met the same confusion before and tell me the reason and how to simulate PTAC reasonably.

Often times you will find that a DX system is more efficient, in particular, if you are using a VRF system that utilizes VFD's on all the fans and the compressors, with HRV/DCV outdoor air system utilizing design economizer and with tight DDC variable control of all zones and systems. A chiller/boiler system always has pump power, that uses additional power, that has to be overcome. That said, a chiller system, if put together with an evaporative condenser or cooling tower, with evaporative, so called, "free cooling", economizer, with VFD's on pumps/fans/compressors, VAV system, great variable control of chilled water and hot water for zone control, might have equal or lower energy use than a VRF system and may have great control. Often the first cost of chiller boiler system is higher. Both can be great systems, depending on how they are set up and controlled. David A. Bastow McClure Engineering, Inc.

So the program outputs 2 sim files - the base(proposed, CHW) case and the iterated (DX) case We want to use eQuest to validate the system choice on this particular project. This is work that was started before I joined, but I have been selected to try and use eQuest to compare the performance of a chilled water system and a DX system. I'm not the most experienced energy modeler, but it seems like a task that would be a good application for eQuest. My approach was to simulate the energy consumption of a building that is similar to the actual design in orientation, shape, and square footage. I initially built the model in the SD wizard, using most of the default values (building envelope, activity usage, etc.), autosize the equipment, and use the EEM to compare the two systems. The idea was that when the building construction and geometry are equal, we can look at the relative energy consumption of the two systems. This initial simulation reported that the DX system would be more efficient, which is not what I had expected based on the design that had been selected. So I figured that maybe my model was too generic, too simple. I created zones based on the plans, and made the geometry more representative of the actual building. These changes produced reports that suggest the chilled water system is more efficient than the DX. I realized that the EEM was incorrectly modeling the change - it was treating the chilled water system as having all 8 air handlers, but was modeling the DX system as one AHU. So I created a duplicate model that has a DX system (autosized and using equest defaults). The comparison of these two models suggests the DX system is slightly more efficient. Unfortunately, my lack of experience makes me doubt the validity of this comparison - especially considering that the engineers selected a chilled water system for this project. So I suppose my questions are: Does my approach seem valid? Is this an appropriate use of the software? After taking some time to write this note, and with a little rest, I wonder if comparing the proposed design to an ASHRAE 90.1 baseline would have been a better approach.

If that's the case, my general advice is that you should much more heavily weight the comparative results using your "actual/proposed" model. A baseline per above inherently diverges from the actual building materials, lighting power densities, solar load shading, and so forth. It's not the same building. Best to choose systems that most efficiently handle your actual project. Don't get too hung up what works best for an imaginary building ;). ~Nick cid:489575314 at 22072009-0ABB NICK CATON, P.E.

It would seem that this is a great opportunity to use the EEM, and the simulation predicted that the CHW configuration would be more energy efficient than the DX system. To be conservative, I also made a copy of the baseline model and changed the system from chilled water to DX. Using this method, the simulation predicts that the DX system would be more efficient (although not by much). Which result is most accurate? The building is a car dealership with a large showroom and an air-conditioned parts storage area. The geometry and building envelope are not exact, but I made this decision because we are doing this for comparison purposes, so the geometry and construction will be the same. I have let eQuest autosize both systems. Sincerely, Matt Clough -------------- next part -------------- An HTML attachment was scrubbed...

There have been many discussions centered around green roofs, but nobody has established a "best practice" to my knowledge. You will have to ultimately define for yourself what course of action is most appropriate for your current project. Limitations to how eQuest handles constructions have led many to recommend EnergyPlus and it's brethren (such as Designbuilder), where approximations such as assuming a constant soil dampness are unacceptable. If a specific end-goal is to model a green roof as accurately as possible, it seems reasonable to consider other software options. I can't speak much further to exactly how to get started with EnergyPlus - something I'm still working on myself. If you're comfortable with approximations inherent to using eQuest, you could optionally account for the shading effects of vegetation with a building shade + shading schedule appropriate to the seasonal shading effects. Thermal mass/conductivity of the soil, assuming a certain constant dampness, should be represented in a custom layered construction. For that construction, reflectivity should be representative of the soil surface. Consider increasing the roof surface area beyond its actual boundaries to account for thermal conduction of the vegetation. Hmm - maybe I've just set a standard? Some have suggested the net thermal effects of green roofs, inclusive of nuances eQuest cannot account for, are rendered negligible when the layers & thermal mass comprising a green roof are situated external to (above) a significant layer of insulation. I haven't heard of any studies investigating this, but it's very much worth considering from an energy modeling perspective. If the net thermal effects turn out to be negligible, that's reasonable grounds for deciding to not include the green roof at all in the model - it may be time-efficient to build a separate model to explore this specific possibility for your project's local climate and green roof properties. ~Nick NICK CATON, P.E.

I am not an expert on eQUEST. I used DOE2.1E to estimate the performance of PV as described below. The results may be questionable. I would like to have case studies of modeling PV with eQUEST. PV Case Studies Projects on http://bepan.info/ Proj-8 - eQ-Tutor - CCGT (modified) - DL+GSHP+PV http://bepan.info/projequest/p8-ccgt-pv-gshp Proj-8 used the PV option of eQUEST-DOE22. I have not tried to understand the PV theory and how it converts solar light energy to electricity. I am not sure whether I modeled the input right because I copied the input described in: http://bepan.info/iit-eq-sem-08/q5-pv-gshp DOE22-eQUEST PV-Documentation Proj-11 - DOE21E - Chicago Center for Green Tech - DL+GSHP+PV http://bepan.info/proj-bldgs/p11-ccgt-doe21e Proj-11 used DOE2.1E (does not have PV option) and uses the hourly report of radiation (direct, diffuse, total) falling on a surface. It assumes the light energy falling on PV is the same (??). Create a bldg with a wall (or roof surface) with an azimuth and tilt angle of the proposed PV panel and the area of the PV panel. 10 years ago when the study was done the efficiency of PV was about 9% to 12%. Now the manufacturers claim up to 17%. In the study 10% (I think) of the total btuh radiation falling on the surface was assumed can be converted to kwh electricity. Proj-12 - eQ-DOE21E - MSCC - Middle-School + Community-Center http://bepan.info/proj-bldgs/p12-middle-school Proj-12 applies the renewable energy savings (PV, GSHP, day-lighting) options of Proj-11 CCGT and creates a bldg (design criteria based on a RFP from client) that enhances the performance. Proj-21 ? DOE21E - Beijing - Solar-Radiation ? PhotoVoltaics ? Study http://bepan.info/proj-doe21e/p21_beijing-solar-pv Proj-21 also analyzes solar data using DOE2.1E. Proj-13 - eQ-DOE21E - HRMU - High-Rise Mixed-Use Bldg http://bepan.info/proj-bldgs/p13-high-rise-bldg Note that the PERCENT energy savings (base Std90) for a low-rise bldg in a suburban location with land for GSHP can be 50% but for a high-rise bldg in an urban location with high land costs and surrounded by tall bldgs the percent energy savings is small. Compare Proj-12 & Proj-13. There are plans to create a database of case studies. Statistical analysis of existing bldgs can be used to estimate the energy performance of new bldgs.

Any help would be appreciated. A multifamily high rise residential will be heated by floor convectors with both natural and forced convection. In most cases, natural convection will be sufficient (this is the experience of the mechanical engineer) and warmed air will rise from these convectors into the spaces. In colder weather, the convectors will operate their fans for more airflow. I have not been able to find much about modelling such a device. My intuition tells me that system Fan Coil would be the best candidate, but with fan power and airflow tied to a schedule that is dependent on outside air temperatures. Is this possible in eQuest? The difficult part is that in warmer weather fan power will be zero and there will be some airflow, while in colder weather fan power will appear and there will be higher airflows.

There are a few schools of thought out there regarding exactly how cooling EIR should be derived from a fan-inclusive energy rating (it's my understanding future versions/addenda to 90.1 may address/clarify this with a sort of generic set of "non-fan cooling/heating efficiency factors"), but you should not be entering 0.0 energy for your fan in any case. Presently, one can choose to figure a baseline system cooling EIR using either the baseline Pfan or ARI procedure fan power figures... I have used both without consequence, and the two methods (usually) produce similar results, but I have gathered over time approaches based on ARI fan energies are easier to pick up and may be more widely practiced, so I'll describe that approach here. The archives contain a few discussions (look for my name) describing Pfan-based methods as well: - Use the modeled capacity (SV-A) and prescribed EER to determine the Total system energy at full capacity. - Determine the fan power as specified by the ARI rating procedures (365W/CFM) using the modeled baseline system airflow (SV-A). This is distinct from Pfan. - Subtract the ARI fan energy from the total system energy. The result is the non-fan energy. - Divide this remainder (non-fan energy) by the capacity (SV-A) and adjust/convert as necessary to make the ratio unitless - now you've found cooling EIR. Interesting to note: I've learned HAP's baseline automation tools use an ARI-based procedure much like the above, but further tweaks the numbers to account for local design conditions differing from ARI test conditions. In practice this makes the same baseline system in very hot design conditions like Arizona cool less efficiently than in more temperate design conditions... It took me awhile but I've come to wrap my head around the logic. Does anybody using eQuest or otherwise doing these baseline calcs "by hand" perform a similar efficiency 'de-rating' in their spreadsheet calcs? ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

From the energy breakdown contrast, what surprises me is that the energy for cooling is more than before.

What controls the heat output, and what triggers the fans to come on? Are the convectors electric heating or hot water? Is there a separate air handler for ventilation? How about modeling the convector heating as hot water (regardless of whether or not they are). Assign two boilers (electric if the convectors are electric), one with a separate boiler pump to represent the convector fan, and one without. Create an equipment control that uses the boiler without pump as the first stage of heating, and the boiler with pump as the second stage. This method models the fans as coming on at a certain stage of heating load, instead of them coming on per a time schedule or OA schedule. Some other ideas: If the convectors are hot water, you could model them as hot water baseboards, and add a miscellaneous load with a schedule that mimics the hours that the convector fan would run. If the convectors are electric, you could model them as hot water baseboards with an electric boiler, and the HW loop pump can represent the fan. Add a miscellaneous load with a schedule that mimics the hours that the convectors are natural convection only. You could also try to model the convectors as variable volume, so that the fan curve results in lower fan power at lower loads.

Any help would be appreciated. A multifamily high rise residential will be heated by floor convectors with both natural and forced convection. In most cases, natural convection will be sufficient (this is the experience of the mechanical engineer) and warmed air will rise from these convectors into the spaces. In colder weather, the convectors will operate their fans for more airflow. I have not been able to find much about modelling such a device. My intuition tells me that system Fan Coil would be the best candidate, but with fan power and airflow tied to a schedule that is dependent on outside air temperatures. Is this possible in eQuest? The difficult part is that in warmer weather fan power will be zero and there will be some airflow, while in colder weather fan power will appear and there will be higher airflows.

A fan powered convector will provide much more heat than one without the fan. Typically I set the baseboard capacity to10-15% of the heat capacity of the fan powered convector. This will vary for hot water heating systems based on the HW and space temperatures. The balance of the heating capacity is then used for the fan coil or unit heater.

Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis. The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly? (I would be happy to find out I made some error, but can not find any such errors on my part, and someone told me that the tool does not work so I doubt it is error on my part) *Jeremiah D.

The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly? (I would be happy to find out I made some error, but can not find any such errors on my part, and someone told me that the tool does not work so I doubt it is error on my part) Jeremiah D.

URL: From Jeff.Hirsch at DOE2.com Thu Apr 26 19:52:24 2012 From: Jeff.Hirsch at DOE2.com (Jeff Hirsch) Date: Thu, 26 Apr 2012 19:52:24 -0700 Subject: [Equest-users] Is eQuest still under development ? Message-ID: The Mark Twain quote is most appropriate. Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the ?controversy? here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts ? we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise. However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990?s, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity ?legs? than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps ? For some reason I and others in my group do not get all the emails from this forum ? of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. -------------------------------------------------------------------------------- Jeff Hirsch James J.

Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis.

Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly?

In-Reply-To: References: Message-ID: Jeremiah to your original query: If you'll look to the archives you'll see many have asked the same question. I and others have responded to many of these repeat queries with a cohesive answer: those of us who have invested the time to explore the 90.1 compliance tool have concluded it is a work in progress at best. The documentation specific to using the compliance ruleset says as much, and it is quite true. If you asked the mailing lists in the past and got no response, I'm personally sorry if that caused any bad feelings but that unfortunately is the nature of the beast at times: the supply/demand ratio for individuals with enough time to help out a stranger doesn't always favor those with the questions - that's a primary reason the archives are so important as a support resource. Everyone: Knowing what the compliance tools presently accomplish, I have myself resolved to generally advise others to avoid using it entirely in its current state, for any project on a tight deadline. Newer users especially are better off and will save time focusing on learning to build their own baselines from their proposed models, until this set of features is further along. I would encourage more intermediate/advanced users to give these compliance options a try, explore the implicit workflow adaptations, and draw/learn from how baselines are put together in an automated fashion - but *not* on a real project with a pending deadline. You might very well pick up a few "aha!" tips along the way that save yourself time and improve/enlighten your understanding of modeling for LEED, but don't count on the compliance tools to be a timesaver or even totally function for a given project. A LEED feature I DO recommend all users trying, whether you are using the compliance ruleset or not: File -> Export File -> LEED Results This is something everyone should stop and experience once with a completed project. Depending on how long you've been working with LEED+eQuest - this could be a real timesaver if adapted into your workflow. The time in a workflow you would use this in an active project would be upon finishing your proposed and baseline models (with rotations), and before beginning to tackle the LEED templates. The resulting file pulls a lot of inputs together I am used to printing a stack of reports to draw from. I hope development of LEED features in future eQuest releases fleshes this area out further - exporting a "LEED input report" for uploading to LEED Online would be great. At first I thought this would be unreasonable/unwieldy, but I have input to share on this front if this seems within reason for the development team. ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the "controversy" here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts - we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise. However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990's, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity "legs' than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps - For some reason I and others in my group do not get all the emails from this forum - of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. ________________________________ Jeff Hirsch James J.

List, I do not mean to cause controversy but I am going to re-post this to see if it gets a response this time. When I had an issue I tracked down the phone number for the Hirsch's of 805-532-1045, and left a voicemail, then was texted back the message "please send email to jeff.hirsch at doe2.com and when I emailed the below I never got a response, and after that as well as after much research showed there is no DOE funding, or sales revenue to fund the eQuest project assumed that the project is "dead"....If I am wrong, someone from the eQuest development team please respond to my questions? Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis. The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly? (I would be happy to find out I made some error, but can not find any such errors on my part, and someone told me that the tool does not work so I doubt it is error on my part) Jeremiah D.

However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990?s, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity ?legs? than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps ? For some reason I and others in my group do not get all the emails from this forum ? of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. ________________________________ Jeff Hirsch James J.

List, I do not mean to cause controversy but I am going to re-post this to see if it gets a response this time. When I had an issue I tracked down the phone number for the Hirsch's of 805-532-1045, and left a voicemail, then was texted back the message "please send email to jeff.hirsch at doe2.com and when I emailed the below I never got a response, and after that as well as after much research showed there is no DOE funding, or sales revenue to fund the eQuest project assumed that the project is "dead"....If I am wrong, someone from the eQuest development team please respond to my questions? Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis. The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly? (I would be happy to find out I made some error, but can not find any such errors on my part, and someone told me that the tool does not work so I doubt it is error on my part) Jeremiah D.

The Mark Twain quote is most appropriate. Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the "controversy" here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts - we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise. However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990's, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity "legs' than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps - For some reason I and others in my group do not get all the emails from this forum - of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. _____ Jeff Hirsch James J.

List, I do not mean to cause controversy but I am going to re-post this to see if it gets a response this time. When I had an issue I tracked down the phone number for the Hirsch's of 805-532-1045, and left a voicemail, then was texted back the message "please send email to jeff.hirsch at doe2.com and when I emailed the below I never got a response, and after that as well as after much research showed there is no DOE funding, or sales revenue to fund the eQuest project assumed that the project is "dead"....If I am wrong, someone from the eQuest development team please respond to my questions? Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis. The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly? (I would be happy to find out I made some error, but can not find any such errors on my part, and someone told me that the tool does not work so I doubt it is error on my part) Jeremiah D.

Schedules for HVAC fans that provide outdoor air for ventilation shall run continuously whenever spaces are occupied and shall be cycled on and off to meet heating and cooling loads during unoccupied hours." so separating outdoor ventilation from fan cycling does not appear (to me) to be the intent of the app g requirement. why would a fan that provides outdoor air for ventilation be required to operate if it is not providing outdoor air? e.g. doas system or outdoor air supply fan separate from fan in the ahu, or even if the outdoor air ventilation fan is the ahu supply fan (per app g, 3.1, 4). how does the requirement (6.4.3.4.3) apply to an evaporatively cooled system with zero return air? i.e. no return air path. or an evaporative system with no return air path in cooling mode but 80% return in heating mode when mated with a furnace section? app g, 3.1, 4, sounds more logical (to me) without even getting into the debate about how to properly simulate a baseline building system of system type 3 or 4 when the proposed building system is an evaporative cooler with 100% outside air.

You will need to peruse the variety of options to find more precisely what you're thinking of. The attached discussion from the archives should help you find where to get started. "Hourly Temperature" can suggest a lot of things - if you're looking for temperature in a room that is a zone variable. If you're looking for a temperature in a specific airstream that is probably a system variable. Best advice here is to take a few minutes to explore what is available under all the various categories to build a degree of familiarity, and be sure to select a zone/system/space/loop/etc... that applies to what you're investigating specifically. Humidity ratios can be tracked for a variety of airstreams: return, mixed air, after coils, after humidification/de-humidification and so on... All these are system variables, though there exist a few zonal/terminal system options as well. Best of luck! ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

It also has a nine story (full height) atrium that will be used to extract all of the exhaust air (i.e. supply OA to the floors and condition via FC units and pull exhaust air out of the top of the atrium). I'm aware that eQuest doesn't track air flows but I'd like to best approximate the atrium effects on the overall energy use of the building. Current approach: I've modeled each floor as a separate zone and I'm going to delete the floors and turn the ceilings into air-walls and link them to the zone above. Currently I'm conditioning all of the zones that make up the atrium but at some point I'd like to explore not conditioning these zones to more accurately approximate how we'd run the building. Comments? One alternate approach I've seen proposed is to replace all nine zones in the atrium with one full height zone - the advantage is the glass on the roof and upper walls can "see" the floor and walls in all of the zones of the atrium. However this won't let me later go back in and explore any variation of temperature with height. I think this might be important as I would expect the air at the top of the atrium to be warmer and cause more load on the top floor zones next to the atrium. -- Jason Quinn From jeremiah at cleantechanalytics.com Mon Apr 2 14:05:52 2012 From: jeremiah at cleantechanalytics.com (CleanTech Analytics) Date: Mon, 2 Apr 2012 14:05:52 -0700 Subject: [Equest-users] Advice on modelling nine story atrium across shells In-Reply-To: References: Message-ID: Sounds like a task that would be better done with single zone and analysed using CFD to me..

Make an assumption about how much load is displaced or only present in the plenum portion of the atrium. Then, put a portion of the glazing and loads in the plenum(s). You might for example assume that the bottom two floors are one conditioned zone, and the top seven floors are a large plenum. I believe the air in the plenum should pick up the heat from the glazing and loads placed in it. I would be cautious about using eQuest to predict what will actually happen in an atrium though.

Short of toying with the azimuth/orientation inputs, which it sounds like you've done, my next guess would be to compare the contents of your daylight sensor's inputs in the .inp against a known working model's - perhaps something will stick out as obvious. Also on re-reading, I wonder if it has to do with the orientation of your contributing window? Try toying with that as well...

As according to "Treatment of district or campus thermal energy in LEED v2 & LEED 2009", a virtual plant with default efficiency can be used. There are few questions regarding the COP as well as the thermal loss: a) The COP of cooling plant shall be 4.4 including cooling towers and primary pumps. Does it mean that chillers, cooling towers as well as primary pumps shall be sized with COP 4.4? how can we enter the pump and cooling tower efficiency with COP4.4? Or we just only need to input COP 4.4 for chillers while the others can use the rated efficiency in our design? b) How can we input the thermal distribution losses? What I suppose is that, Q=mcdT, so if there are 5% thermal loss, the dT loss shall also be 5%. Does it mean to enter 5% of design dT in the "supply loss dT" column? Or make it simple, just multiplying 5% to the energy consumption by space cooling is already sufficient? Thanks all.

I have been looking into the window/drapes functions, i.e. the possibility of changing blind positions over 3 different seasons. I didn't find, though, the possibility of switching on ambient conditions, as suggested by Michael. How can you do that? It's quite interesting the possibility of uploading an annual hourly schedule into the software. Do you think I can generate an excel schedule setting different values for some parameters (window properties such as VLT and SHGC) and import them into E-quest to run my model? It's not a perfect solution but I could have for sure a good estimate of the savings.

Within the Window, under Blinds/Drapes-Switching, there is an option for switching of window properties. This is to represent windows with electrochromic switching. As far as I know (I've never actually used it) it can only switch between two sets of window properties. But it can be switched on various ambient conditions (solar gain, temperature, etc). If thats not sophisticated enough, you could try using an 8760 hour schedule generated in Excel. Output all the data you need (OAT, solar gain, etc), then do your calculations in Excel to generate your shading schedule and import it into your file. Or if you really want a function, Doe2.1e allows them. But they're not very user friendly...

I was wondering if the software already had a function reproducing basically what electro-chromic windows do, that's basically maintaining a constant illuminance level in a room, reducing solar heat gain and light transmittance accordingly. If not, then it might be an idea to try and implementing this function, as I reckon it might be useful in various application.

The Blinds/Drapes - Switching tab has several options that allow you to vary conductance, solar transmission, etc. during the course of a simulation. It's meant to represent variable shading, so you can decide if that's scientific enough for what you're doing. The only other "easy" way I can think of is to run the model with both (or all) of the skylight options, and stitch the results together (March through August with one, the remainder with the other for example). The effect would be the same as if a guy went up and swapped out the glass one day. You'd have to lock down equipment sizing and a few other things to make sure that's the only difference, but still easier than adding your own eQUEST feature. Maybe you're better with code than me though! Good luck however you decide to do it.

I am not sure how I can account for the energy efficiency gains compared to base case through a high SRI roof. - I am trying to model a large gated community with 330 villas and 7 other common buildings. As someone suggested on this group I am modeling each building type separately and using excel to come up with a total energy usage. But I am not sure how to model the street lighting and landscape lighting at the exteriors. We plan to use solar street lights and I want to demonstrate the savings through use of solar energy.

I run into this often as I move projects around and work on them from different locations. The .dwg file itself is never an "integral/imported" part of the project's files - only a path is defined, so eQuest will prompt you on starting up for the CAD file's location any time the project's files or the CAD file is moved around (to be expected if you're working with others on a thumb drive or similar). To re-emphasis John's point: This isn't something to lose sleep over =). The "CAD file not found" message is something you can safely ignore entirely once you are past zone/perimeter geometry definitions in the wizards. The CAD file is not actually used anywhere in eQuest beyond serving as a "reference" for the duration of those screens. Once you are finished defining zone/perimeter geometries in wizards, you can feel safe choosing "remove all" from the following dialog: [cid:image001.png at 01CD165C.FB457D50] For the duration where your group may wish to go back and revise those geometries using the CAD file, I'd advise keeping a copy of the .dwg file alongside other "reference" files to "browse" to as needed. As an organizational practice/suggestion, I commonly have a small "reference" directory that I'll save and move around alongside the actual model files containing items like this and other notes, PDF's, messages, and other electronic information I used while assembling the model. Keeping this stuff in one place can make many things easier down the road, even well after finishing the project-at-hand! ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

For these simulations I've been using a very simple office model with a skylight on the top as a test-bed for my calculations (with default system for HVAC and daylighting controls with dimming for lights) but, observing the values I'm obtaining in output, I see that the values I obtain for lighting, cooling and heating consumption make sense relatively, i.e. if compared to themselves in different conditions, but are sometimes of totally different order of magnitude if compared to each other (lighting/cooling loads are often much higher than heating, by orders of magnitude), especially when scaling up the model to bigger sizes. This way, it's very difficult to see the effect of a variable change on the total energy consumption. I know the model I'm using is very idealized, but is there any variable that I can act on in order to obtain a model which has energy consumption values more similar to a real building? For example, is there a "suggested" size of the building that gives better results? Or maybe simulating a single room in a large building gives more realistic results than the single room alone? My point is that I would like to have a model whose results in scale might be consistent when applied to bigger buildings.

I've done plenty of simulation runs, which basically covered different types of buildings, of different sizes, in different locations. Of course different parameters grow with different laws, and if lighting wattage is strictly related to the building area, heating/cooling loads are influenced by the lateral surfaces and perimeter zones. This makes perfectly sense, and it was somehow what I expected to see. Said that, let me explain a little better my question: when I write about different results, I can probably show the point with an example. I take a 5x5x3m building with one skylight on the top (4% SRR) and I get certain values for lighting and HVAC loads. Then I simulate the same exact building with 50x50x6m dimensions, with 4% SRR for skylight, and I get lighting and cooling increasing by a factor of 100, heating by a factor of 10. I also have real data for this larger building, and I simulated it in Energyplus as well, and both these comparisons confirmed that heating and cooling should grow in a similar way in a temperate climate. So my question is, since I want to keep the model simple, especially on the HVAC side, which are the most important variables in Equest which might lead me to more consistent results without bringing excessive complexity into the model. Of course I'm not looking for a unique building which could be valid for all cases, but I'm caring about model consistency and validation.

I have performed studies with similar structure as Karen is suggesting (creating and adding "building blocks" to evaluate building massing options). However, for Stefano's purposes I would caution to carefully take stock of what questions you are trying to answer and whether an energy model is really the way to go about finding those answers. Using an energy model to develop generic guidelines with "arbitrary" buildings/spaces for something inherently site/climate/building-geometry-specific (such as "ideal window wall ratio" or "ideal window properties") is actually a terribly complex endeavor, as I'm sure you are appreciating. You can ultimately come up with a set of guidelines/spreadsheets/principles to use, but applying such developed guidelines to an actual project for decision-making will always be fraught with accuracy disclaimers (perhaps that is not the ultimate goal - I'm only throwing this out for consideration). Guidelines built around generic conditions are indeed useful and have their place (ASHRAE's advanced energy design guides are worth reviewing if you're at the outset of trying to find such results), but should only be relied upon in the context of "I don't want to invest in a site-specific study and the increased accuracy / differing suggestions that may produce." Evaluating how well any study applies to the project-at-hand is something to always keep in mind. To cut myself off: I think my response drafted so far is falling away from Stefano's original question as he's more recently clarifying it, but I'm ultimately driving towards furthering Karen's first line: Build project-specific models where you need a project-specific answer. To Stefano's issue of scaling - I am nodding my head vigorously as you're observing how spaces modeled in isolation do not always additively represent a group of spaces modeled together. It's possible for that to happen under certain circumstances, but the variables in play do not normally scale linearly between an isolated space and a whole building (consider the ratio of envelope surface area to conditioned volume, for one instance). A big part of "big picture" modeling differences when compared to "the smaller parts" is the tempering of various loads across spaces and the way that has energy saving effects on HVAC systems in particular . I would not spend too much time deliberating on such (expected) differences, and would emphasize focusing on the results of isolated or "whole building" models as appropriate to the purpose of your study =). ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

I have performed studies with similar structure as Karen is suggesting (creating and adding "building blocks" to evaluate building massing options). However, for Stefano's purposes I would caution to carefully take stock of what questions you are trying to answer and whether an energy model is really the way to go about finding those answers. Using an energy model to develop generic guidelines with "arbitrary" buildings/spaces for something inherently site/climate/building-geometry-specific (such as "ideal window wall ratio" or "ideal window properties") is actually a terribly complex endeavor, as I'm sure you are appreciating. You can ultimately come up with a set of guidelines/spreadsheets/principles to use, but applying such developed guidelines to an actual project for decision-making will always be fraught with accuracy disclaimers (perhaps that is not the ultimate goal - I'm only throwing this out for consideration). Guidelines built around generic conditions are indeed useful and have their place (ASHRAE's advanced energy design guides are worth reviewing if you're at the outset of trying to find such results), but should only be relied upon in the context of "I don't want to invest in a site-specific study and the increased accuracy / differing suggestions that may produce." Evaluating how well any study applies to the project-at-hand is something to always keep in mind. To cut myself off: I think my response drafted so far is falling away from Stefano's original question as he's more recently clarifying it, but I'm ultimately driving towards furthering Karen's first line: Build project-specific models where you need a project-specific answer. To Stefano's issue of scaling - I am nodding my head vigorously as you're observing how spaces modeled in isolation do not always additively represent a group of spaces modeled together. It's possible for that to happen under certain circumstances, but the variables in play do not normally scale linearly between an isolated space and a whole building (consider the ratio of envelope surface area to conditioned volume, for one instance). A big part of "big picture" modeling differences when compared to "the smaller parts" is the tempering of various loads across spaces and the way that has energy saving effects on HVAC systems in particular .

As you mentioned, the ratio between lighting/cooling/heating changes depending on the size of the building. I'm willing to guess that this is because the core zones that have very little need for heat get much larger in relation to the perimeter zones. Also, the building energy needs will change depending on orientation and global location. I would suggest that you take a slightly different approach - try to come up with values that are representative for different types of spaces. You might do say: 1. A perimeter office space with XX% glazing (run for North, East, South and West exposures) 2. A core office space with no skylights 3. A core office space with XX% of roof area as skylights 4. A core manufacturing space??? 5,6,7.... Run each model in the applicable climate. Then, if you have an office building that is 70% core and 30% perimeter space, you'll have a better understanding of the building.

Yes - eQUEST is frustrating and it's a pain in the backside sometimes to try to make it do what you want it to. Maybe Energyplus is a better program to use for this. However - I don't think workarounds are necessarily a bad thing. In my experience - if you are experimenting with workarounds, it enhances your understanding of the process you are trying to model, and as a result makes you more thoughtful and allows you apply critical thinking to the process. Ultimately - most modeling is about that last item - critical thinking.

On second thought a better way to scale would he to maintain the ratio of length x width / height x ((2 x length) + (2 x width)) If height is constant then a 10x10 space scaled up ten times floor area would best scale to something like 194x5.1 (excuse calculations, no calculator doing this at red lights). Where other issues arise like the exposure of the long face will make a big impact.

Did I find the eQUEST version of a video game cheat code? (Any reason I shouldn't use these ScrollChlr curves?)

data from a vendor. Also, I don't think there is a development team anymore, they all work on E+ now. I was just looking at this today, I had a job with scroll chillers. Just at a glance I noticed the EIR =f(PLR) curve is a lot more linear than the screw chiller curve. The limited part load data I had for my chiller seemed to suggest it was a lot more non linear. So your mileage may vary. Also make sure that you normalize any curves that you use to your design EIR. The default curve is EIR2(1) = .1305 . Elechour = Caphour * EIR * EIR1f(t1,t2) * EIR2f(PLR) / 3413 Btu/kW So if you don't normalize it is going to think it's using a fraction of the energy that it should be.

You didn't describe how many unmet hours you have or what you have tried already. Unmet heating hours can result from underheating, but also from overcooling. Depending on what you change in the model, you might end up increasing your heating energy, or you can end up reducing both cooling and heating energy. Here are a few things to try: ? Enter a value for the system REHEAT-DELTA-T. Leaving this blank can result in thousands of unmet heating hours. ? Set the system COOL-CONTROL to something other than CONSTANT, provided the system you are modeling has the controls capability. I have had success with WARMEST and RESET. ? If you change COOL-CONTROL to COLDEST or WARMEST, increase the zone THROTTLING-RANGE from the default 2?R (2?F). 4?-6? is recommended. You can start with 3? and increase by 0.5? to see how the unmet hours change. If you are comparing two models or two system types, keep the same throttling range in both models to make it a fair comparison. ? Adjust air flow rates, such as your system and/or zonal MIN-FLOW-RATIO. Search the archives here: http://lists.onebuilding.org/pipermail/equest-users-onebuilding.org/ You could always post your .inp and .pd2 files and someone might look at your model.

If you select 1 piece of equipment using auto sizing, the equipment will make the 21 people comfortable for the one hour. The autosizing sizing is for the design condition. Since the auto sizing balances for the case of 20 in one room and 1 in the other. When there are 0 people in 1 room and 1 in the other, you will likely get unmet load hours.

I assume you're in the context of lights. What's appropriate depends on how you have set up your model and to what degree their operation needs to be modeled explicitly. A few approaches, from simple to involved: * Established 90.1 Appendix G approach: Assign a flat % reduction to the installed LPD for the space(s) with occ sensors (only in those that don't already require them, if you're actually doing a proposed/baseline performance rating). * Define alternate fractional schedules that represent hourly operation of lights with and without occ sensors. This can be approached with a few variations to achieve the same result. Some choose to apply a % reduction to the schedules instead of the installed watts per space, achieving an identical result. * Redefine space occupancy schedules in a manner that makes them appropriate to assign to the lighting loads as well (i.e. setting 1.0 for occupied hours), and use the same schedules for both occupancy and lighting - if accuracy is critical, you'll want to consider moving away from a "whole building" fractional schedule as generated by the wizards and move towards "per space type" scheduling. In this scenario the hourly occupancy value is multiplied against the installed Watts for each space, so you could correctly account for an occ. sensor's time delay into an unoccupied hour with a fractional value. More creative (and potentially convoluted) solutions are out there that might fit your model on a case-by-case basis, but the three above are approaches I've used more than once. ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

Set up your first building (ideally as a single shell), then create new shells by copying the first - editing the rotation and internal layout as necessary. If/when you have everything set up, you can save multiple copies of the file and remove the shells you don't want for each case to isolate to the correct building. You shouldn't need re-enter the same information twice. To something Yusuf mentioned earlier: Modeling the savings of solar street/landscape lighting can be re-stated as determining the energy consumption of a "non-solar equivalent." This is a lot trickier than it may seem on the surface. Much of that complexity is tied up in what "non-solar equivalent" means in reality: Dig hard at the cutsheets of the solar equipment in question to come up with some hard numbers for photometrics and runtime realities. If you are not trained/familiar with photometric lighting design software you may want to engage someone who is to help you along the way. [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

I will dig around a bit on that one. Creating multiple files does not seem to work. I do not understand why. With regards to your second suggestion, Indian Green Building Council have asked me not to waste time modeling the street lights. They asked me to use an excel sheet to calculate the total lighting consumption by multiplying the base case LPD of 2.4 W/Sq Mt with total area under lighting and average hrs of usage. In the proposed case I simply have to subtract the total outdoor lighting consumption from the overall energy consumption since it is powered using solar. I thought it makes sense.

Sounds like the only thing for you to nail down is operating hours of the solar lights. Regarding the DD wizard... I'm suggesting starting with one file then later splitting into multiple files, as you suggested for use with an external spreadsheet, to appropriately multiply the results without a massive model of the entire campus. Here is a quick illustration: [cid:image002.png at 01CD17F4.C52FDDC0] After completely finishing "Building A," defined as a single shell, click "create new shell" and choose to copy "Building A." You can then make only the necessary edits to orientation, space layout, window layout, etc... and other inputs will be repeated from the copied shell. Repeat that procedure for as many unique buildings as you require, then when finished you can proceed with saving the project a few times and in each project removing the shells you do not need to isolate to one building. Hope that helps get my suggestion across better! ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

I will dig around a bit on that one. Creating multiple files does not seem to work. I do not understand why. With regards to your second suggestion, Indian Green Building Council have asked me not to waste time modeling the street lights. They asked me to use an excel sheet to calculate the total lighting consumption by multiplying the base case LPD of 2.4 W/Sq Mt with total area under lighting and average hrs of usage. In the proposed case I simply have to subtract the total outdoor lighting consumption from the overall energy consumption since it is powered using solar. I thought it makes sense. Thank You very much. Yusuf On 12 April 2012 00:34, Nick Caton > wrote: To Yusuf's more recent question below: What you're describing (varying the rotation/layout only with all else remaining constant) sounds most easily accomplished in a single file, within the wizard stage. Set up your first building (ideally as a single shell), then create new shells by copying the first - editing the rotation and internal layout as necessary. If/when you have everything set up, you can save multiple copies of the file and remove the shells you don't want for each case to isolate to the correct building. You shouldn't need re-enter the same information twice. To something Yusuf mentioned earlier: Modeling the savings of solar street/landscape lighting can be re-stated as determining the energy consumption of a "non-solar equivalent." This is a lot trickier than it may seem on the surface. Much of that complexity is tied up in what "non-solar equivalent" means in reality: Dig hard at the cutsheets of the solar equipment in question to come up with some hard numbers for photometrics and runtime realities. If you are not trained/familiar with photometric lighting design software you may want to engage someone who is to help you along the way. [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

It is easy to use. I believe that a newer version was recently released - we're still using the 1994 version. However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis. I included Jeremiah's response below which suggests that Energy Plus can do these calculations. This was my impression, however I have never used E+ to do them.

In-Reply-To: References: <07BF4294A620CF4C9BF3280086050EE10186EC59@camaro.BCE.local> Message-ID: Alex you are correct, eQuest does not know the surface temperatures required to calculate the Mean Radiant Temperature. eQuest /DOE2 uses the Cooling Load Temperature Difference (CLTD) method to arrive at heat loads in a space. This approach makes approximations of the radiant component of heat transfer and does not directly calculate radiant gains or losses. Because of this, any DOE2 based software at best can predict air temperature and moisture needed for a PMV calc. EnergyPlus or IES are the only engines that can produce hourly surface temp information and therefore, mean radiant temperature averages. If you are interested in providing comfort feedback of envelope changes and not HVAC changes, learning EnergyPlus using OpenStudio from NREL is well worth the time and effort. Their workflow takes some practice to adopt but once you get the hang of things, creating buildings is very easy. Their youtube channel is best for explaining this, search for OpenStudio and NREL.

I'll second the suggestion to purchase the Thermal Comfort tool. It is easy to use. I believe that a newer version was recently released - we're still using the 1994 version. However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis. I included Jeremiah's response below which suggests that Energy Plus can do these calculations. This was my impression, however I have never used E+ to do them.

It uses Weighting Factors (also known as Room Response Factors) that characterize the dynamic response of a space for a given input of heat flow. Envelope heat flows are similarly calculated using Response Factors that are also dynamic, i.e., they capture the thermal lag and capacitance of the materials. Radiant heat gains are taken into account in both response factors (using the sol-air temperature method) and weighting factors (there are different weighting factors for different types of heat gain). However, radiant heat gains are ignored in interzone heat transfer. Although DOE-2 doesn't compute inside surface temperatures, they can be output (in DOE-2.1E at least) and I've that little-known feature to do PMV calculations. Lastly, DOE-2 has always been able to model the humidity of the indoor air. What it doesn't do (which may be what you're thinking) is that it doesn't model the absorption/desorption of moisture in the building fabric.

Or the rule set might be failing because it doesn't know the ASHRAE climate region for your location (Mumbai). I assume that you have a weather file for Mumbai. I recently created last year a set of weather files for 38 Indian locations for ISHRAE, so if you have any problems there, just give me a holler. However, even if you get these practical problems resolved, I question the logic of creating an ASHRAE-90 building as the reference or comparison building for your study, which would set all the building conditions to ASHRAE-90 requirements. I would recommend that, instead, you create a reference building based on India's ECBC, or if you don't think that's being widely followed yet, on what you think are the typical construction and operating conditions in Mumbai. I can also think of several friends in India, even Mumbai, that I could recommend if you need help. It seems that you're thinking of modeling a green roof as an additional soil layer. That's okay for starters, but if that's the topic of your thesis, you should do a more careful job and incorporate the following characteristics that makes a green roof differ from just 20 cm of dirt on top: (1) changing soil moisture depending on the time of year and rainfall, and (2) evaporatranspiration that would keep the soil surface temperature low on sunny days. This is not a marketing pitch, but in DOE-2.1E (an earlier version of the DOE-2.2 engine in eQUEST) that I still use, there is a feature called "Functions" that would allow users to insert additional code in pseudo-Fortran to model processes not covered by the program. If you're interested, we can discuss more offline. Again, this is not a marketing pitch.

If you shut off your dehumidification limit of 50%, it eliminates the summer heating issue. Also, I don?t know how much control you have over your economizer settings, but if you haven?t read this article , I?d strongly suggest it. As an interesting aside ? that author?s comments on RH sensor reliability matches well with what I?ve found on a recent project. Here?s a little data I?ve gathered from a college campus. I harvested 24hr trend data from all the buildings that were measuring OA humidity (y-axis in %). The fat blue line is what I got from the National Weather Service for the area and each other line represents a building?s OA humidity sensor. I think in total these sensors control at least 25 AHU?s enthalpy economizers. From what I can tell, they don?t have a regular PM routine for calibrating/replacing these sensors. Just something to consider?

I've dropped the thermostat in the summer months on the heating and am still getting a load. Any ideas on why there would be a load?

In-Reply-To: References: <07BF4294A620CF4C9BF3280086050EE10186EC59@camaro.BCE.local> Message-ID: 8760 hourly inside zone wall surface temp and MRT at a point in space is not very useful. It might be useful in Loads program based on design day conditions in summer and winter. See http://bepan.info/engg-calcs - 3a - Design-Weather-Generator DOE2.1E uses the Transfer Function method to calculate envelope heat transfer. I think Trane-TRACE and Carrier-HAP use the same method. The CLTD-SCL-CLF method is still very useful for teaching envelope heat transfer. See http://bepan.info/class-notes/e4-project-loads The Total Equivalent Temperature Difference (TETD) method is also useful for teaching. See - http://bepan.info/hvac-prog/x1-apec-hccv-loads It is difficult to explain the heat storage capacity and time lag concepts of the envelope with the other methods although all Loads calculations are done by computer today. The APEC (Automated Procedure for Engineering Consultants) HCC-V Loads program can be downloaded and used. If you don?t know what the ?decrement factor? is, use 0.5 since the range is between 0 and 1. An estimate for ?time-lag? depends on the type of bldg. In design loads calculation for commercial buildings it is important NOT to underestimate the loads. The hourly Fortran Variable report of the DOE2 based programs include outside wall surface temp. In the DOE2 Loads section choose (1) Variable-Type = u-name of EXTERIOR-WALL (2) Variable List Number 5 Q Heat transfer from wall to the zone un-weighted (Btu/hr) (3) Variable List Number 6 T Outside surface temperature (Rankine). Transfer the values of Q and T to an Excel spreadsheet and calculate the inside wall surface temps. Examples of calculating inside surface temp using outside surface temp. http://bepan.info/proj-doe21e/p22_kuwait-shell-mrt Proj-22 - Kuwait-Envelope-Temps-MRT-Systems-Study? I have found the hourly Fortran Variable report by the DOE2 program very helpful. Transfer the hourly data to an Excel spreadsheet and do the rest yourself.

URL: -------------- next part -------------- Alex you are correct, eQuest does not know the surface temperatures required to calculate the Mean Radiant Temperature. eQuest /DOE2 uses the Cooling Load Temperature Difference (CLTD) method to arrive at heat loads in a space. This approach makes approximations of the radiant component of heat transfer and does not directly calculate radiant gains or losses. Because of this, any DOE2 based software at best can predict air temperature and moisture needed for a PMV calc. EnergyPlus or IES are the only engines that can produce hourly surface temp information and therefore, mean radiant temperature averages. If you are interested in providing comfort feedback of envelope changes and not HVAC changes, learning EnergyPlus using OpenStudio from NREL is well worth the time and effort. Their workflow takes some practice to adopt but once you get the hang of things, creating buildings is very easy. Their youtube channel is best for explaining this, search for OpenStudio and NREL.

I'll second the suggestion to purchase the Thermal Comfort tool. It is easy to use. I believe that a newer version was recently released - we're still using the 1994 version. However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis. I included Jeremiah's response below which suggests that Energy Plus can do these calculations. This was my impression, however I have never used E+ to do them.

See http://www.whiteboxtechnologies.com/ Click here for the Open Letter to Lawrence Berkeley National Lab (LBNL) on Open Source DOE-2.1E.) DOE2.1E is particularly suited for academic thesis research for the following reasons: 1. It is a mature computer program that has been in extensive use for nearly 30 years. In fact, its latest proprietary version (DOE-2.2/eQUEST) is clearly the most widely used building energy simulation program in the US, if not the entire world. 2. Compared to other simulation programs, DOE-2 runs very quickly. 3. Since DOE-2.1E has been in effect abandoned by DOE and LBNL, its code can be made open source, and be freely available to students and researchers 4. DOE-2.1E contains a User Function option that allows users to develop additional modules or tweak existing calculations without having to change and recompile the existing source code. User Functions are ideal for student applications. Those that are promising can then later be incorporated into the source code itself. Here are suggestions of how to fix DOE-2.1E so that it can be used for academic thesis research 1. Provide better documentation and examples of building models and User Functions. 2. Develop teaching materials on how to use the DOE-2 program, including how to extract hourly data, use macros to manage sensitivity analyses, and available open-source user interfaces. 3. Freeze the existing code since it is error-free and make it possible for research students to add/attach independent sub programs to expand the features of DOE-2.1E. The independent (or dependent) sub-programs that can be interfaced with DOE-2.1E should include PV-modules, GSHP, UFAD, DOAS, Radiant-ceilings and other features not included in DOE-2.1E. There could be multiple versions of each sub-program by different authors. 4. A DOE-2.1E committee should establish common output reports for them. You can expect advanced program development using an open source DOE2.1E as the base launching pad from enterprising architects, engineers, academics in the areas renewable energy and also in testing new concepts. The analogy is countries like socialist India and communist Russia & China opening up development to individual free enterprise. All the economies are now booming after 15 years. Their economies stagnated during the previous 50 years of the government doing everything. Trane & Carrier have their own energy programs (TRACE and HAP) based on their equipment and systems. Other manufacturers can now create energy programs starting with the open source DOE2.1E and base it on their own equipment. These would be program developers that are involved with real buildings from design through construction and operation and understand the business. Equipment consumes energy in buildings, not the envelope or people. Manufacturers would therefore have vested interest in making sure that their energy programs produced results that are close to the building in operation. ----- Original Message ----- From: Joe Huang Date: Sunday, April 15, 2012 2:15 pm Subject: Re: [Equest-users] Urgent request > Sharma, > > eQUEST is a program developed in the US, so its compliance rule > set > might not work for locations outside of the US. > Or the rule set might be failing because it doesn't know the > ASHRAE > climate region for your location (Mumbai). etc > This is not a marketing pitch, but in DOE-2.1E (an earlier version > of > the DOE-2.2 engine in eQUEST) that I still use, there > is a feature called "Functions" that would allow users to insert > additional code in pseudo-Fortran to model processes > not covered by the program.

I finally found what I was looking for, and it looks like this has been the goal of a DOE project concluded in 2008. In the website I linked below, there are listed some models of commercial building prototypes which have demonstrated to fit most of the commercial buildings in the US, and which could serve as a starting point for modeling energy efficiency measures without the risk of having results dependent on the specific modeling assumptions, of course within reasonable ranges. There are also the IDF files which serve as input for E+. To recall the elephant and the mouse metaphor, here there?s probably a good reference for consistent mice and elephants prototypes, and that was exactly what I was looking for.

On second thought a better way to scale would he to maintain the ratio of length x width / height x ((2 x length) + (2 x width)) If height is constant then a 10x10 space scaled up ten times floor area would best scale to something like 194x5.1 (excuse calculations, no calculator doing this at red lights). Where other issues arise like the exposure of the long face will make a big impact. If building modeling could be scaled for certain constants this easily them we could do it with little paper wheels like ductulators. Fun to think about though!

Otherwise, as has been mentioned in the previous emails, the ratio of envelope surface area to floor plan area will change. A 10x10x10 building, (heat/cool load-wise), will scale better to a 100x100x100 then it would to a 100x100x10, because the ratio of floor space to envelope area is maintained. Although only the top floor will have roof load. And a skylight will only effect the top floor of the larger scale building. Can you change from a skylight to a window with daylighting? This would scale better.

The results likely represent some sort of curve, and are probably multivariate. My suggestion would be to model large, medium and small scenarios and do hourly reports of the loads to see what is happening at different outside temperatures.

An elephant eats about 5% of their own body weight in food daily. The surface area to mass ratios are vastly different. Heat loss, metabolism (internal loads) and fur are very different. If an elephant had the fur of a mouse it would die from overheating. You can't model a small building and try to extrapolate the results to a large building.

As you mentioned, the ratio between lighting/cooling/heating changes depending on the size of the building. I'm willing to guess that this is because the core zones that have very little need for heat get much larger in relation to the perimeter zones. Also, the building energy needs will change depending on orientation and global location. I would suggest that you take a slightly different approach - try to come up with values that are representative for different types of spaces. You might do say: 1. A perimeter office space with XX% glazing (run for North, East, South and West exposures) 2. A core office space with no skylights 3. A core office space with XX% of roof area as skylights 4. A core manufacturing space??? 5,6,7.... Run each model in the applicable climate. Then, if you have an office building that is 70% core and 30% perimeter space, you'll have a better understanding of the building. This is still a very rough approximation, but should get you farther than trying to model one "typical" building. -- Karen On Mon, Apr 9, 2012 at 4:57 PM, Stefano Moret > wrote: Dear all, I've recently played around quite a bit with E-quest to simulate the effect of dynamic fenestration on building energy consumption. For these simulations I've been using a very simple office model with a skylight on the top as a test-bed for my calculations (with default system for HVAC and daylighting controls with dimming for lights) but, observing the values I'm obtaining in output, I see that the values I obtain for lighting, cooling and heating consumption make sense relatively, i.e. if compared to themselves in different conditions, but are sometimes of totally different order of magnitude if compared to each other (lighting/cooling loads are often much higher than heating, by orders of magnitude), especially when scaling up the model to bigger sizes. This way, it's very difficult to see the effect of a variable change on the total energy consumption. I know the model I'm using is very idealized, but is there any variable that I can act on in order to obtain a model which has energy consumption values more similar to a real building? For example, is there a "suggested" size of the building that gives better results? Or maybe simulating a single room in a large building gives more realistic results than the single room alone? My point is that I would like to have a model whose results in scale might be consistent when applied to bigger buildings.

As an industry we are very in the dark about reasonable/typical infiltration rates. I suspect any model reviewer, GBCI or otherwise would have a difficult time assessing if the claimed savings due to improved air barrier, or whatever strategy is implemented, are reasonable, especially given that there is no clear baseline established by 90.1. However, you could always put forward a well reasoned argument with back up data and studies and it is possible that the reviewer will allow you take credit. Cite some reputable sources. Submit it as an Exceptional Calculation Methodology with the claimed savings separated out from the rest of your model so it can be discretely evaluated. Here is Seattle the city is requiring new projects to conduct full building air leakage testing prior to occupancy with the city receiving the results as part of a data collection effort, presumably so that they can set reasonable requirements for air leakage in the future. Maybe this data can work its way into an upcoming 90.1 cycle and we can all have a more reasonable approach for modeling air leakage.

In ASHRAE 90.1 5.4.3.3 Fenestration and doors: air leakage shall not exceed 2.0L/s m2 for all other products(curtain walls I think). I refer to NFRC400 and the test delta pressure is 75pa. In China the grading standard of curtain wall air tightness is under 10 delta pressure. The 2.0L/s m2(75Pa) is equal to 0.522L/Sm2(10[a) which is much worse than China GB standard(0.278L/sm2, 10pa) However in other sections like chiller cop or lighting Power ASHRAE standard are much more strict than China GB code. Do American people prefer to live with more air infiltration? It confuse me for a long time.

As an industry we are very in the dark about reasonable/typical infiltration rates. I suspect any model reviewer, GBCI or otherwise would have a difficult time assessing if the claimed savings due to improved air barrier, or whatever strategy is implemented, are reasonable, especially given that there is no clear baseline established by 90.1. However, you could always put forward a well reasoned argument with back up data and studies and it is possible that the reviewer will allow you take credit. Cite some reputable sources. Submit it as an Exceptional Calculation Methodology with the claimed savings separated out from the rest of your model so it can be discretely evaluated. Here is Seattle the city is requiring new projects to conduct full building air leakage testing prior to occupancy with the city receiving the results as part of a data collection effort, presumably so that they can set reasonable requirements for air leakage in the future. Maybe this data can work its way into an upcoming 90.1 cycle and we can all have a more reasonable approach for modeling air leakage.

It might be useful in Loads program based on design day conditions in summer and winter. See http://bepan.info/engg-calcs - 3a - Design-Weather-Generator DOE2.1E uses the Transfer Function method to calculate envelope heat transfer. I think Trane-TRACE and Carrier-HAP use the same method. The CLTD-SCL-CLF method is still very useful for teaching envelope heat transfer. See http://bepan.info/class-notes/e4-project-loads The Total Equivalent Temperature Difference (TETD) method is also useful for teaching. See - http://bepan.info/hvac-prog/x1-apec-hccv-loads It is difficult to explain the heat storage capacity and time lag concepts of the envelope with the other methods although all Loads calculations are done by computer today. The APEC (Automated Procedure for Engineering Consultants) HCC-V Loads program can be downloaded and used. If you don?t know what the ?decrement factor? is, use 0.5 since the range is between 0 and 1. An estimate for ?time-lag? depends on the type of bldg. In design loads calculation for commercial buildings it is important NOT to underestimate the loads. The hourly Fortran Variable report of the DOE2 based programs include outside wall surface temp. In the DOE2 Loads section choose (1) Variable-Type = u-name of EXTERIOR-WALL (2) Variable List Number 5 Q Heat transfer from wall to the zone un-weighted (Btu/hr) (3) Variable List Number 6 T Outside surface temperature (Rankine). Transfer the values of Q and T to an Excel spreadsheet and calculate the inside wall surface temps. Examples of calculating inside surface temp using outside surface temp. http://bepan.info/proj-doe21e/p22_kuwait-shell-mrt Proj-22 - Kuwait-Envelope-Temps-MRT-Systems-Study? I have found the hourly Fortran Variable report by the DOE2 program very helpful. Transfer the hourly data to an Excel spreadsheet and do the rest yourself.

URL: -------------- next part -------------- Alex you are correct, eQuest does not know the surface temperatures required to calculate the Mean Radiant Temperature. eQuest /DOE2 uses the Cooling Load Temperature Difference (CLTD) method to arrive at heat loads in a space. This approach makes approximations of the radiant component of heat transfer and does not directly calculate radiant gains or losses. Because of this, any DOE2 based software at best can predict air temperature and moisture needed for a PMV calc. EnergyPlus or IES are the only engines that can produce hourly surface temp information and therefore, mean radiant temperature averages. If you are interested in providing comfort feedback of envelope changes and not HVAC changes, learning EnergyPlus using OpenStudio from NREL is well worth the time and effort. Their workflow takes some practice to adopt but once you get the hang of things, creating buildings is very easy. Their youtube channel is best for explaining this, search for OpenStudio and NREL.

I'll second the suggestion to purchase the Thermal Comfort tool. It is easy to use. I believe that a newer version was recently released - we're still using the 1994 version. However, I'm not sure that it solves Jason's problem - it still requires a user-entered Mean Radiant Temperature which I don't believe eQUEST gives as an output. When we use the tool (specifically for perimeter comfort analysis understanding the impact of different glazing options on comfort) we make some assumptions on wall/floor/ceiling temps, some calculations on glass-temperatures, and some further assumptions on the ratio of glass-to-other surfaces from the occupant's perspective. Based on that we can calculate the PMV for that single point time with those conditions. I've used software in the past that was able to calculate PMV for every hour of the year (so every hour it would combine air temp, a calculated MRT based on surface temps, humidity, etc) and then give an output for how comfortable the space was throughout the year (with hourly outputs of PMV for different spaces). I don't believe that eQUEST gives the necessary information (surface temps) to do this type of analysis. I included Jeremiah's response below which suggests that Energy Plus can do these calculations. This was my impression, however I have never used E+ to do them.

Hope this Helps! "You can tell eQUEST to run multiple Design Days by setting the start day and the number of days in the Design Day Properties dialog box in the detailed interface (don't know about the wizard). For example I normally set the start day to 6/1 and the number of days to 120. That way it will cover all the solar angles from June - September combined with the ASHRAE Cooling DB / WB, and will use the heating/cooling design day schedules specified in the Week Schedules. I figure this should pretty much cover it, although as Carol said there is usually a peak in the weather file that exceeds the ASHRAE conditions." ( http://lists.onebuilding.org/pipermail/equest-users-onebuilding.org/2008-September/000365.html) Before equest will use the Design Day information in the schedules you need to setup actual design days for the simulation to use. You need to do this in the *detailed edit under the Project & Site tab*. You need to create both a heating and cooling design day and then input the desired temperature extremes and duration that you wish to simulate. Reference the climate design data in the ASHRAE Fundamentals Handbook for your location. Once you create the design days equest will use them for equipment sizing rather than the peak heating & cooling loads calculated from the TMY weather data.

So the program outputs 2 sim files - the base(proposed, CHW) case and the iterated (DX) case We want to use eQuest to validate the system choice on this particular project. This is work that was started before I joined, but I have been selected to try and use eQuest to compare the performance of a chilled water system and a DX system. I'm not the most experienced energy modeler, but it seems like a task that would be a good application for eQuest. My approach was to simulate the energy consumption of a building that is similar to the actual design in orientation, shape, and square footage. I initially built the model in the SD wizard, using most of the default values (building envelope, activity usage, etc.), autosize the equipment, and use the EEM to compare the two systems. The idea was that when the building construction and geometry are equal, we can look at the relative energy consumption of the two systems. This initial simulation reported that the DX system would be more efficient, which is not what I had expected based on the design that had been selected. So I figured that maybe my model was too generic, too simple. I created zones based on the plans, and made the geometry more representative of the actual building. These changes produced reports that suggest the chilled water system is more efficient than the DX. I realized that the EEM was incorrectly modeling the change - it was treating the chilled water system as having all 8 air handlers, but was modeling the DX system as one AHU. So I created a duplicate model that has a DX system (autosized and using equest defaults). The comparison of these two models suggests the DX system is slightly more efficient. Unfortunately, my lack of experience makes me doubt the validity of this comparison - especially considering that the engineers selected a chilled water system for this project. So I suppose my questions are: Does my approach seem valid? Is this an appropriate use of the software? After taking some time to write this note, and with a little rest, I wonder if comparing the proposed design to an ASHRAE 90.1 baseline would have been a better approach.

If your primary goal is to compare the relative performance of two systems on the same building, then you can rest assured you've made fine decisions so far. That you're simultaneously tasked with "validating" one choice over another might complicate things in presentation of your results - it depends on how the cookies crumble. More later. eQuest is a capable tool to this end, but I might have cautioned you at the outset that eQuest can quickly become unwieldy for "a simple comparison" when trying to compare certain system types, especially for newer/intermediate users. That said, you are clearly well-invested into this model, and why would anyone want to miss a learning opportunity, right =)? General rule: A more representative model will always produce a 'better' result - the corollary is that 'better' is not always what you're hoping for. "Degree-of-accuracy" is always a balancing act for any model - it's clear you're taking an active role in deciding when/how to improve the model's degree of detail, however. That's enough to satisfy me. So long as you personally feel the model is "representative enough," that's the key litmus test when you're the one presenting the results ;). I would not suggest stopping and building a 90.1 baseline model provided with this extra context, but you could use 90.1 as a broader reference to ensure you are making a fair comparison. For example, 90.1 Appendix G has a section discussing unmet hours and establishes a threshold for both the (90.1) baseline and proposed models. Have you made a similar check between your chiller and DX models to ensure they're on similar footing? I almost always build my models from DD wizards instead of SD so my usual workflow may produce different "normal fixes," but I commonly need to spend extra time reviewing the hydronic inputs in detailed mode to ensure any chiller system is being correctly modeled. Give your chiller, pump, and loop inputs a good scour, particularly pump operation/scheduling inputs. You mentioned also changing the quantity of airside systems for the DX model - it might be worthwhile to review the schedules applicable to the consolidated system to ensure its operating as a single large AHU would. When all is said and done if you still feel uncomfortable with your inputs, I've often found it productive to have the responsible mechanical designer scan through typical waterside/airside inputs alongside me to identify anything that appears off. I have found pulling other designers in is a good QC practice for all skill levels where the modeler didn't do all the work him/herself. I find it easiest to plan on missing some nuances along the way (Murphy's law), and allow those most intimate with the design to collaborate with me to pick any loose threads up. So full-circle... regarding your 'intended' results: Accept that the "right" answer can ultimately swing either way. Whenever performing a comparative study, keep in mind all such results are built on unknowns/assumptions. Where the results are close, it's not uncommon to conclude there are multiple right answers. ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

So the program outputs 2 sim files - the base(proposed, CHW) case and the iterated (DX) case We want to use eQuest to validate the system choice on this particular project. This is work that was started before I joined, but I have been selected to try and use eQuest to compare the performance of a chilled water system and a DX system. I'm not the most experienced energy modeler, but it seems like a task that would be a good application for eQuest. My approach was to simulate the energy consumption of a building that is similar to the actual design in orientation, shape, and square footage. I initially built the model in the SD wizard, using most of the default values (building envelope, activity usage, etc.), autosize the equipment, and use the EEM to compare the two systems. The idea was that when the building construction and geometry are equal, we can look at the relative energy consumption of the two systems. This initial simulation reported that the DX system would be more efficient, which is not what I had expected based on the design that had been selected. So I figured that maybe my model was too generic, too simple. I created zones based on the plans, and made the geometry more representative of the actual building. These changes produced reports that suggest the chilled water system is more efficient than the DX. I realized that the EEM was incorrectly modeling the change - it was treating the chilled water system as having all 8 air handlers, but was modeling the DX system as one AHU. So I created a duplicate model that has a DX system (autosized and using equest defaults). The comparison of these two models suggests the DX system is slightly more efficient. Unfortunately, my lack of experience makes me doubt the validity of this comparison - especially considering that the engineers selected a chilled water system for this project. So I suppose my questions are: Does my approach seem valid? Is this an appropriate use of the software? After taking some time to write this note, and with a little rest, I wonder if comparing the proposed design to an ASHRAE 90.1 baseline would have been a better approach.

The use of the chiller system?s cooling efficiency and pump power will be important since these are known, and may vary from the wizard?s suggestion. You?ll also need to make sure the DX system efficiency and fan power is realistic. The part-load performance of the system could also be important if the hours for the shop and show room are different ? this could be a case where two or more right-sized DX systems may be a better match than one chiller, depending on the magnitude for the loads and if the zones have wildly different hours of operation. My suggestion would be to set eQUEST aside for a half hour, and just run through a table for the fan power, pump power, and cooling efficiency for each of the two cases and see if the answer jumps out at you. If you get pointed strongly in one direction, then review the eQuest files more closely to be sure you are capturing all of the part-load effects. Regarding your ASHRAE 90.1 baseline suggestions, that might be your best ?baseline? and then compare the proposed CHW and an enhanced DX system against that, but shouldn?t be necessary other than as Nick suggests for a QA reference.

From the energy breakdown contrast, what surprises me is that the energy for cooling is more than before. When I try to change the fan delta t from 0.93 to 0 and find the cooling energy is decreasing than inputting the whole EER, but the sum of cooling and fan is still more than inputting the whole EER , have anyone met the same confusion before and tell me the reason and how to simulate PTAC reasonably.

Often times you will find that a DX system is more efficient, in particular, if you are using a VRF system that utilizes VFD's on all the fans and the compressors, with HRV/DCV outdoor air system utilizing design economizer and with tight DDC variable control of all zones and systems. A chiller/boiler system always has pump power, that uses additional power, that has to be overcome. That said, a chiller system, if put together with an evaporative condenser or cooling tower, with evaporative, so called, "free cooling", economizer, with VFD's on pumps/fans/compressors, VAV system, great variable control of chilled water and hot water for zone control, might have equal or lower energy use than a VRF system and may have great control. Often the first cost of chiller boiler system is higher. Both can be great systems, depending on how they are set up and controlled. David A. Bastow McClure Engineering, Inc.

The use of the chiller system's cooling efficiency and pump power will be important since these are known, and may vary from the wizard's suggestion. You'll also need to make sure the DX system efficiency and fan power is realistic. The part-load performance of the system could also be important if the hours for the shop and show room are different - this could be a case where two or more right-sized DX systems may be a better match than one chiller, depending on the magnitude for the loads and if the zones have wildly different hours of operation. My suggestion would be to set eQUEST aside for a half hour, and just run through a table for the fan power, pump power, and cooling efficiency for each of the two cases and see if the answer jumps out at you. If you get pointed strongly in one direction, then review the eQuest files more closely to be sure you are capturing all of the part-load effects. Regarding your ASHRAE 90.1 baseline suggestions, that might be your best "baseline" and then compare the proposed CHW and an enhanced DX system against that, but shouldn't be necessary other than as Nick suggests for a QA reference.

So the program outputs 2 sim files - the base(proposed, CHW) case and the iterated (DX) case We want to use eQuest to validate the system choice on this particular project. This is work that was started before I joined, but I have been selected to try and use eQuest to compare the performance of a chilled water system and a DX system. I'm not the most experienced energy modeler, but it seems like a task that would be a good application for eQuest. My approach was to simulate the energy consumption of a building that is similar to the actual design in orientation, shape, and square footage. I initially built the model in the SD wizard, using most of the default values (building envelope, activity usage, etc.), autosize the equipment, and use the EEM to compare the two systems. The idea was that when the building construction and geometry are equal, we can look at the relative energy consumption of the two systems. This initial simulation reported that the DX system would be more efficient, which is not what I had expected based on the design that had been selected. So I figured that maybe my model was too generic, too simple. I created zones based on the plans, and made the geometry more representative of the actual building. These changes produced reports that suggest the chilled water system is more efficient than the DX. I realized that the EEM was incorrectly modeling the change - it was treating the chilled water system as having all 8 air handlers, but was modeling the DX system as one AHU. So I created a duplicate model that has a DX system (autosized and using equest defaults). The comparison of these two models suggests the DX system is slightly more efficient. Unfortunately, my lack of experience makes me doubt the validity of this comparison - especially considering that the engineers selected a chilled water system for this project. So I suppose my questions are: Does my approach seem valid? Is this an appropriate use of the software? After taking some time to write this note, and with a little rest, I wonder if comparing the proposed design to an ASHRAE 90.1 baseline would have been a better approach.

If that's the case, my general advice is that you should much more heavily weight the comparative results using your "actual/proposed" model. A baseline per above inherently diverges from the actual building materials, lighting power densities, solar load shading, and so forth. It's not the same building. Best to choose systems that most efficiently handle your actual project. Don't get too hung up what works best for an imaginary building ;). ~Nick cid:489575314 at 22072009-0ABB NICK CATON, P.E.

It would seem that this is a great opportunity to use the EEM, and the simulation predicted that the CHW configuration would be more energy efficient than the DX system. To be conservative, I also made a copy of the baseline model and changed the system from chilled water to DX. Using this method, the simulation predicts that the DX system would be more efficient (although not by much). Which result is most accurate? The building is a car dealership with a large showroom and an air-conditioned parts storage area. The geometry and building envelope are not exact, but I made this decision because we are doing this for comparison purposes, so the geometry and construction will be the same. I have let eQuest autosize both systems. Sincerely, Matt Clough -------------- next part -------------- An HTML attachment was scrubbed...

There have been many discussions centered around green roofs, but nobody has established a "best practice" to my knowledge. You will have to ultimately define for yourself what course of action is most appropriate for your current project. Limitations to how eQuest handles constructions have led many to recommend EnergyPlus and it's brethren (such as Designbuilder), where approximations such as assuming a constant soil dampness are unacceptable. If a specific end-goal is to model a green roof as accurately as possible, it seems reasonable to consider other software options. I can't speak much further to exactly how to get started with EnergyPlus - something I'm still working on myself. If you're comfortable with approximations inherent to using eQuest, you could optionally account for the shading effects of vegetation with a building shade + shading schedule appropriate to the seasonal shading effects. Thermal mass/conductivity of the soil, assuming a certain constant dampness, should be represented in a custom layered construction. For that construction, reflectivity should be representative of the soil surface. Consider increasing the roof surface area beyond its actual boundaries to account for thermal conduction of the vegetation. Hmm - maybe I've just set a standard? Some have suggested the net thermal effects of green roofs, inclusive of nuances eQuest cannot account for, are rendered negligible when the layers & thermal mass comprising a green roof are situated external to (above) a significant layer of insulation. I haven't heard of any studies investigating this, but it's very much worth considering from an energy modeling perspective. If the net thermal effects turn out to be negligible, that's reasonable grounds for deciding to not include the green roof at all in the model - it may be time-efficient to build a separate model to explore this specific possibility for your project's local climate and green roof properties. ~Nick NICK CATON, P.E.

I am not an expert on eQUEST. I used DOE2.1E to estimate the performance of PV as described below. The results may be questionable. I would like to have case studies of modeling PV with eQUEST. PV Case Studies Projects on http://bepan.info/ Proj-8 - eQ-Tutor - CCGT (modified) - DL+GSHP+PV http://bepan.info/projequest/p8-ccgt-pv-gshp Proj-8 used the PV option of eQUEST-DOE22. I have not tried to understand the PV theory and how it converts solar light energy to electricity. I am not sure whether I modeled the input right because I copied the input described in: http://bepan.info/iit-eq-sem-08/q5-pv-gshp DOE22-eQUEST PV-Documentation Proj-11 - DOE21E - Chicago Center for Green Tech - DL+GSHP+PV http://bepan.info/proj-bldgs/p11-ccgt-doe21e Proj-11 used DOE2.1E (does not have PV option) and uses the hourly report of radiation (direct, diffuse, total) falling on a surface. It assumes the light energy falling on PV is the same (??). Create a bldg with a wall (or roof surface) with an azimuth and tilt angle of the proposed PV panel and the area of the PV panel. 10 years ago when the study was done the efficiency of PV was about 9% to 12%. Now the manufacturers claim up to 17%. In the study 10% (I think) of the total btuh radiation falling on the surface was assumed can be converted to kwh electricity. Proj-12 - eQ-DOE21E - MSCC - Middle-School + Community-Center http://bepan.info/proj-bldgs/p12-middle-school Proj-12 applies the renewable energy savings (PV, GSHP, day-lighting) options of Proj-11 CCGT and creates a bldg (design criteria based on a RFP from client) that enhances the performance. Proj-21 ? DOE21E - Beijing - Solar-Radiation ? PhotoVoltaics ? Study http://bepan.info/proj-doe21e/p21_beijing-solar-pv Proj-21 also analyzes solar data using DOE2.1E. Proj-13 - eQ-DOE21E - HRMU - High-Rise Mixed-Use Bldg http://bepan.info/proj-bldgs/p13-high-rise-bldg Note that the PERCENT energy savings (base Std90) for a low-rise bldg in a suburban location with land for GSHP can be 50% but for a high-rise bldg in an urban location with high land costs and surrounded by tall bldgs the percent energy savings is small.

There are a few schools of thought out there regarding exactly how cooling EIR should be derived from a fan-inclusive energy rating (it's my understanding future versions/addenda to 90.1 may address/clarify this with a sort of generic set of "non-fan cooling/heating efficiency factors"), but you should not be entering 0.0 energy for your fan in any case. Presently, one can choose to figure a baseline system cooling EIR using either the baseline Pfan or ARI procedure fan power figures... I have used both without consequence, and the two methods (usually) produce similar results, but I have gathered over time approaches based on ARI fan energies are easier to pick up and may be more widely practiced, so I'll describe that approach here. The archives contain a few discussions (look for my name) describing Pfan-based methods as well: - Use the modeled capacity (SV-A) and prescribed EER to determine the Total system energy at full capacity. - Determine the fan power as specified by the ARI rating procedures (365W/CFM) using the modeled baseline system airflow (SV-A). This is distinct from Pfan. - Subtract the ARI fan energy from the total system energy. The result is the non-fan energy. - Divide this remainder (non-fan energy) by the capacity (SV-A) and adjust/convert as necessary to make the ratio unitless - now you've found cooling EIR. Interesting to note: I've learned HAP's baseline automation tools use an ARI-based procedure much like the above, but further tweaks the numbers to account for local design conditions differing from ARI test conditions. In practice this makes the same baseline system in very hot design conditions like Arizona cool less efficiently than in more temperate design conditions... It took me awhile but I've come to wrap my head around the logic. Does anybody using eQuest or otherwise doing these baseline calcs "by hand" perform a similar efficiency 'de-rating' in their spreadsheet calcs? ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

From the energy breakdown contrast, what surprises me is that the energy for cooling is more than before. When I try to change the fan delta t from 0.93 to 0 and find the cooling energy is decreasing than inputting the whole EER, but the sum of cooling and fan is still more than inputting the whole EER , have anyone met the same confusion before and tell me the reason and how to simulate PTAC reasonably.

What controls the heat output, and what triggers the fans to come on? Are the convectors electric heating or hot water? Is there a separate air handler for ventilation? How about modeling the convector heating as hot water (regardless of whether or not they are). Assign two boilers (electric if the convectors are electric), one with a separate boiler pump to represent the convector fan, and one without. Create an equipment control that uses the boiler without pump as the first stage of heating, and the boiler with pump as the second stage. This method models the fans as coming on at a certain stage of heating load, instead of them coming on per a time schedule or OA schedule. Some other ideas: If the convectors are hot water, you could model them as hot water baseboards, and add a miscellaneous load with a schedule that mimics the hours that the convector fan would run. If the convectors are electric, you could model them as hot water baseboards with an electric boiler, and the HW loop pump can represent the fan. Add a miscellaneous load with a schedule that mimics the hours that the convectors are natural convection only. You could also try to model the convectors as variable volume, so that the fan curve results in lower fan power at lower loads.

A fan powered convector will provide much more heat than one without the fan. Typically I set the baseboard capacity to10-15% of the heat capacity of the fan powered convector. This will vary for hot water heating systems based on the HW and space temperatures. The balance of the heating capacity is then used for the fan coil or unit heater.

URL: From Jeff.Hirsch at DOE2.com Thu Apr 26 19:52:24 2012 From: Jeff.Hirsch at DOE2.com (Jeff Hirsch) Date: Thu, 26 Apr 2012 19:52:24 -0700 Subject: [Equest-users] Is eQuest still under development ? Message-ID: The Mark Twain quote is most appropriate. Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the ?controversy? here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts ? we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise. However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990?s, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity ?legs? than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps ? For some reason I and others in my group do not get all the emails from this forum ? of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. -------------------------------------------------------------------------------- Jeff Hirsch James J.

In-Reply-To: References: Message-ID: Jeremiah to your original query: If you'll look to the archives you'll see many have asked the same question. I and others have responded to many of these repeat queries with a cohesive answer: those of us who have invested the time to explore the 90.1 compliance tool have concluded it is a work in progress at best. The documentation specific to using the compliance ruleset says as much, and it is quite true. If you asked the mailing lists in the past and got no response, I'm personally sorry if that caused any bad feelings but that unfortunately is the nature of the beast at times: the supply/demand ratio for individuals with enough time to help out a stranger doesn't always favor those with the questions - that's a primary reason the archives are so important as a support resource. Everyone: Knowing what the compliance tools presently accomplish, I have myself resolved to generally advise others to avoid using it entirely in its current state, for any project on a tight deadline. Newer users especially are better off and will save time focusing on learning to build their own baselines from their proposed models, until this set of features is further along. I would encourage more intermediate/advanced users to give these compliance options a try, explore the implicit workflow adaptations, and draw/learn from how baselines are put together in an automated fashion - but *not* on a real project with a pending deadline. You might very well pick up a few "aha!" tips along the way that save yourself time and improve/enlighten your understanding of modeling for LEED, but don't count on the compliance tools to be a timesaver or even totally function for a given project. A LEED feature I DO recommend all users trying, whether you are using the compliance ruleset or not: File -> Export File -> LEED Results This is something everyone should stop and experience once with a completed project. Depending on how long you've been working with LEED+eQuest - this could be a real timesaver if adapted into your workflow. The time in a workflow you would use this in an active project would be upon finishing your proposed and baseline models (with rotations), and before beginning to tackle the LEED templates. The resulting file pulls a lot of inputs together I am used to printing a stack of reports to draw from. I hope development of LEED features in future eQuest releases fleshes this area out further - exporting a "LEED input report" for uploading to LEED Online would be great. At first I thought this would be unreasonable/unwieldy, but I have input to share on this front if this seems within reason for the development team. ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.

Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the "controversy" here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts - we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise. However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990's, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity "legs' than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps - For some reason I and others in my group do not get all the emails from this forum - of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. ________________________________ Jeff Hirsch James J.

Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis. The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly?

The Mark Twain quote is most appropriate. Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the ?controversy? here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts ? we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise.

Sambhav, if you're working on a leed project can you ask the review team (thru the project on leed online) to clarify which oa requirement method should be followed in the simulation - app g or 6.4.3.4.3?

The Mark Twain quote is most appropriate. Thank you Chris. Our group rarely participates in these forums, but I felt some response to this somewhat annoying rumor was needed. Some of the discussion also brings to mind another familiar proverb: a bad workman always blames his tools. But also I am reminded that, if all you have is a hammer everything looks like a nail. So I add to the "controversy" here. eQUEST and DOE-2 are alive and well and our combined development efforts are at an equal or higher funding and effort level than ever before. However, we will continue to provide all our DOE-2 and eQUEST products as freeware to the simulation communities around the world. We support the overall community activities so that the community can offer analysis and support services to derive income based upon use of our products. We tend not to compete with the community by offering those same analyses and support services ourselves with the exception of providing eQUEST and DOE-2 training. Thus we as a group do not normally offer fee based support services except to a small group of our long-term clients who also generally support our development efforts - we leave those fee based support service opportunities to you, the user community, as an income source. With thousands of eQUEST and DOE-2 installation around the world, we receive too many emails per day to possibly respond. We especially cannot respond to standard support requests as that request should be directed to those offering fee based support services. We try to pay attention and examine requests when program bugs or errors are suspected. But quite often we need to delay any fixes to the next program release. Our focus on DOE-2.3 and program develop environment changes for both eQUEST and DOE-2 has slowed our releases for the past two years. That will change this year, so be patient please. We do not develop eQUEST or DOE-2 using a license fee income based model. Rather we develop our tools to support the analysis needs of our major clients and the general user community. We have no plans to change our model. Like all software, eQUEST and DOE-2 will have quirks, bugs and limitations. No realistic or truthful company offering software could claim otherwise. However, we plan to continue making improvements and have the resources to do so. What is coming? Several things are coming in the next year. DOE-2.3 has been in beta for some time. We will release that new version when we are confident it can be used in production work in place of DOE-2.2. A version of eQUEST that fully supports DOE-2.3 that will be released at the same time. DOE-2.2 is also still under development, but we tend to implement all major new features in DOE-2.3 rather than DOE-2.2. We expect to release an update to both eQUEST and DOE-2.2 soon with DOE-2.3 and its eQUEST version later. The DOE-2.2 refrigeration version development continues, however more priority has been placed on DOE-2.3 recently; however, we will also release an update to that application as well and we consider that version an important product to continue to upgrade well into the future. I am not sure why rumors of the impending death of DOE-2, that started in the late 1990's, continue to persist since the evidence for the past fifteen years should have proven those rumors wrong. Similarly, the rumors about the death of eQUEST that have appeared more recently can be also similarly be ignored as completely false. The real history shows that our DOE-2 and eQUEST products have proven to have more funding and longevity "legs' than any other existing similar software. While other development groups struggle to advance one simulation program or one user interface we have shown that our group can do both the engine and interface with major advances to both for decades and as freeware. I see no change coming in our ability to continue the upgrade of both in the current decade. You should, as a community, be more concerned with the long term viability of other groups making big claims that have a long way to go before they can claim to be offering the simulation community the mature, stable, reliable capabilities free as you get from our products. It is much easier for a developer to claim their product can do amazing things than it is for the user community to realize those possible gains while maintaining the ability to deliver services to their clients competitively in a timely manner. We plan to do our best to continue to offer you products that allow you to perform your job or earn a living, and keep your clients satisfied. In return we ask for your continued support, patience and generally good vibes. We also ask that you continue to support one another in this and other forums, as the freeware nature of our products requires the user community to hang together and exchange information and ideas. With that, I return to my observation deck. ps - For some reason I and others in my group do not get all the emails from this forum - of the multiple emails Mr. Crossett sent to the forum and myself below I received none but I did, obviously see the one I am now responding to. Not sure of the cause, but I do get hundreds of emails per day and cannot even open many. _____ Jeff Hirsch James J.

List, I do not mean to cause controversy but I am going to re-post this to see if it gets a response this time. When I had an issue I tracked down the phone number for the Hirsch's of 805-532-1045, and left a voicemail, then was texted back the message "please send email to jeff.hirsch at doe2.com and when I emailed the below I never got a response, and after that as well as after much research showed there is no DOE funding, or sales revenue to fund the eQuest project assumed that the project is "dead"....If I am wrong, someone from the eQuest development team please respond to my questions? Jeff, I am working on a LEED compliance building model in eQUEST, and have to ask you a question. So I created a building that has zero insulation, standard lighting watts/sqft and ran the compliance analysis. The building that is not at code energy costs are in the sixty thousand range, and the 0,90,180,270 average that should be at code is in the ninty thousand range.This %30 savings for the building that has zero insulation over the building that has been auto generated to be complaint with ASHRAE/LEED shows that for some reason the building that is not at code (zero insulation) uses 30% less then the building that is suppose to be at code, and I am sure that the software is wrong. Now I have read the PDF published on the subject, and am very curios if the compliance analysis tool is something that you believe to work correctly? (I would be happy to find out I made some error, but can not find any such errors on my part, and someone told me that the tool does not work so I doubt it is error on my part) Jeremiah D.

You will need to peruse the variety of options to find more precisely what you're thinking of. The attached discussion from the archives should help you find where to get started. "Hourly Temperature" can suggest a lot of things - if you're looking for temperature in a room that is a zone variable. If you're looking for a temperature in a specific airstream that is probably a system variable. Best advice here is to take a few minutes to explore what is available under all the various categories to build a degree of familiarity, and be sure to select a zone/system/space/loop/etc... that applies to what you're investigating specifically. Humidity ratios can be tracked for a variety of airstreams: return, mixed air, after coils, after humidification/de-humidification and so on... All these are system variables, though there exist a few zonal/terminal system options as well. Best of luck! ~Nick [cid:489575314 at 22072009-0ABB] NICK CATON, P.E.
