[Equest-users] Equest-users Digest, Vol 48, Issue 20

[Danny Xu]

Hi all,
 
In one of my projects, I changed the flr to flr height in the INP file (the height is not allowed to be changed in detail model).   After run the changed INP file, I can see the height changed in detail model, but the simulation results does not change, no mater how great change it is.  Does anyone have the same experience and know the reason? 
 
Thanks.
Danny

I am modeling a building that will use steam produced by a Coal Fired central plant. My baseline system is system 3, PSZ, fossil fuel fired for multiple zones. 
  
Per LEED's  District Thermal Energy V2, section 2.4.2.2, exception A, "For fuels used at the central plant that are not available at the building use the central plant rates for that fuel type in the Baseline and Proposed Case." 
  
My understanding is that I will use an 80% efficient gas fired furnace for each PSZ, and then apply the heating value and cost of coal to the amount of BTU's used? 
  
Is this a correct interpretation?

Hi, everyone:
I check the help files , it seems like this is different of equipment control sequence.  
If a load control with priority = 2, it should be run first, and which one priority = 1 should be the second, is that right?
Below is the help files.
I think in the below example , “CTRL-PRIORITY-2    = 1”shold be OK, because the equipment control have a default priority of 0, why it set it 10 as below? Maybe I think too much. 
Thank you for your helpJ
Joey
 
“Accepts a numeric value in the range of 1-100, where 1 is the lowest priority, and 100 is the highest. This value is the command priority that applies to all EQUIP-CTRL sequences listed under EQUIP-CTRL-n. You can define multiple LOAD-MANAGEMENT sequences and these sequences can broadcast conflicting EQUIP-CTRL sequences to the various loops. The program resolves these conflicts via CTRL-PRIORITY-n. For a given loop or electric meter, the EQUIP-CTRL sequence broadcast with the highest priority will override all others. Note that EQUIP-CTRL sequences attached locally to a loop via the CIRCULATION-LOOP:HEAT-EQUIP-CTRL or COOL-EQUIP-CTRL have a command priority of 0. This allows all LOAD-MANAGEMENT broadcasts to override the locally defined control. 
This keyword also applies to the LOOPS-ON-n and LOOPS-OFF-n instructions.
You can enter multiple sets of data using the CTRL-FLAG-n, TEMPS-THRU-n, EQUIP-CTRL-n, and CTRLS-PRIORITY-n sets of keywords. Normally, you should define set #1 first, then set #2, etc.
Not all control ranges need to have values. For example, if you are defining a control sequence of TYPE = OA-TEMP, and want to override the local loop control only when the outdoor temperature exceeds 90F, your input could be:
LM-HIGH-TEMP = LOAD-MANAGEMENT
TYPE               = OA-TEMP
TEMPS-THRU-1       = 89.
TEMPS-THRU-2       = 120.
EQUIP-CTRLS-2      = (EC-ABSOR,EC-GENERATE)
CTRL-PRIORITY-2    = 10    ..
In this example, EQUIP-CTRL-2 will be used whenever the outdoor temperature is above 89F, and EQUIP-CTRL-1 will be used when the temperature is lower than 90F. However, since there are no EQUIP-CTRL sequences listed in EQUIP-CTRL-1, no sequences will be broadcast.”

Dear Wesley and Michael, 
  
Thanks for your suggestions. 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. 
  
Thanks, Stefano

Hi Stefano. 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...

Thanks Wesley, 
  
Nice to know that I can schedule different window properties by schedule, this is a simplified approach that might give an estimate of the saving. 
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. 
  
Thanks, regards

Hi Stefano, 
  
Before you start trying to recode eQUEST, you might see if the scheduling options in the Window Properties window will be close enough approximations for you. 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. 
  
Thanks,

I actually don’t want to change much to the model itself, I just want to give different properties to materials (or change components) in different times of the year. Let’s say, I want to use a type of skylight in winter that’s different from the one I use in summer, by changing the model of the skylight or some of its main parameters. Do you think this might be possible? Maybe adding some external script?

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?

Hi Stefano. Switching is under window properties, Blinds tab. See graphic below.
 
To do it in Excel requires a bit of playing around with the formatting. Once you’ve done that you can save the Excel sheet as a prn file, which will turn it into text and it can be copied into the inp file and re-imported. But getting the formatting straight can be a bit of work.

Thanks, I see what you mean, I’ll try and use the EMIT schedule generator for that. 
For what I see, with shades I can set set a schedule for solar heat gain, and from the daylight tab I can regulate visible light transmittance. 
It’s nice that you can switch on daylight levels as control parameter, would be nice it to be adapting as electro-chromic windows and not 0/1 as it is here. 
  
Thanks for your inputs, Regards

Thanks Jeremiah, 
  
I actually don’t want to change much to the model itself, I just want to give different properties to materials (or change components) in different times of the year. Let’s say, I want to use a type of skylight in winter that’s different from the one I use in summer, by changing the model of the skylight or some of its main parameters. Do you think this might be possible? Maybe adding some external script? 
  
Thanks, Stefano

I do not believe so, but you can try lots of different configurations that you either draw, or trace from cad..

Hi, 
  
I’m new to the use of E-quest, I’m just starting to play around with it by performing some preliminary simulations. 
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? 
  
Thanks for your attention,  
Best Regards 
Stefano
