[Equest-users] Do I define the zone as unconditioned?

Hi,
 
I am modelling a community center which has swimming pool in the basement.  The upper boundary of swimming pool is not ground floor but the 2nd floor.  In the ground floor, the swiming area - the zone open to the below swimming pool should be defined as unconditioned or conditioned?  It make nonsense to heating or cooling this area.  And the same situation in the 2nd floor, a basketball court is high to the top of 3rd floor, the zone in the 3rd floor above the court should be conditioned or not?  
 
Thanks,
Danny

It appears that I have found a bug in eQuest when Oregon is selected for location. 

For example, is you use the canned two story office building (25,000 square feet), which has Packaged Single Zone systems, the cooling and heating capacity (see SV-A System Design Parameters Reports) for the core zone; ground and top floors; will differ……which
makes sense…..the top floor needing more than the ground floor. 

Change the location to Washington (Seattle), and the cooling and heating capacity varies between the top and ground floors for the core zone.  Like it does for California.  OKAY. 

Change to Oregon, any city, and the cooling and heating capacity values for the top and ground floor zones are always exactly the same!!! 

Anyone else run across this problem before?  Have a fix I can implement? 

Thank you.

One potential workflow is Revit >
Ecotect > eQuest.  
  
If you google exporting Revit to Ecotect there
are several videos / step by step instructions to show you what you need to do
to prepare the model. It mainly has to do with how you define rooms, which
become your thermal zones. However, Ecotect to eQuest I haven’t been able
to do very successfully. There seems to be some problems with exporting the
geometry and zones properly (which is really the major and some would say only benefit).
The only thing I was able to import were wall constructions, which I would
rather define in eQuest anyways. I haven’t been able to find a thorough
explanation of what to do in Ecotect to prepare your geometry for eQuest. FYI, Ecotect
also exports to gbXML, Energy Plus, Radiance, etc. 
  
Another workflow is Vasari > eQuest. Vasari
is an, as of now, free Autodesk program in trial stages that is basically Revit
combined with some basic DOE2 based energy modeling capability, really just for
comparing different scenarios in early design. In my opinion this software is
not ready for creating more complex models as I found creating the zones lacks
the flexibility most models would need - The software will automatically create
zones based on ASHRAE 90.1 perimeter set backs, 1 per floor, etc. Unless you
have an open office plan, this is probably not what you need. You can define
your zones manually, but not easily in my opinion. http://labs.autodesk.com/utilities/vasari/ - if you’re interested. 
  
I’ve tried to look into this a few
times now, and all things considered it seems that importing 3D geometry is not
that big of a timesaver compared to the design wizard, if at all. If anyone has
experience with these workflows, I would be grateful to hear it.

I agree. The argument is that with importing from Revit there is already a 3d model available. The issue normally is that there is too much information in the Revit model and most often it needs a LOT of clean up. Its potentially easy if you are a person with really fantastic model management skills (I haven’t met one yet).

I’ve tried using .gbxml to import 3D models, but the zones did not import correctly.  I’ve heard that it’s best to recreate the model in eQuest.  I am interested in how this DrawBDL 3.0 will work.  I’m sure if there was a way of importing the design model into the energy model, all teams would greatly benefit from the decreased amount of time wasted on rebuilding a model.  This would be a good round table discussion on the best way of importing the design model into an energy model.

I like this conversation cause it is one that I have battled with for a long time.
 
I’m going to respond on top of the previous comments in saying that it all depends on your comfort with software and 3D modeling. As below I agree with Vikram that at the moment it is easier to just model the project directly in eQuest and not import at all. Let me however tell you that I have built models in eQuest, Vasari, REVIT and Ecotect and they all work fine as long as you understand the basic principles of computer modeling. Vasari is definitely not ready for prime time however you can use it as your integrated modeler between eQuest and REVIT.
 
The one main issue that I have run into and it is working as an architect and coordinating with our engineer that I have found out that architectural REVIT models with gbXML information looks totally different than the zoning model for an HVAC layout used in eQuest. The ways these models are constructed are total different even though the exterior skin might look the same.
 
I’ve done this before but I have attached images of all the softwares to show the model.
 
Just stick with the wizard for now unless the geometries are extremely complex.
 
Thanks,

This email and any files transmitted with it are confidential and intended solely for the addressee. If you are not the named addressee you should not disseminate, distribute, copy, or alter this email.
it is also good to remember that gbxml translations are not 100% accurate yet.  a study a few years ago indicated that major vendor (autodesk, bently, archicad, etc) translations to/from gbxml were only about 90% so if you take something that's 90% accurate & convert it once you've introduced a 10% error rate.  make changes to a translated gbxml file & translate it again & you're 81%.  i'm thinking with time the accuracy may increase but there's not really an incentive, financial or otherwise, for autodesk (or others) to make their files 100% compatible with their competitors despite their public announcements of cooperation on the matter.  equest/energy+ are still competitors to their own non-free energy simulation software. 

a few years ago i wrote some translation software to go from gbxml
    to .pd2/.inp for just the building components
    (spaces/walls/roof/windows/floors) & found a) it worked better
    going to wizard mode than detailed mode (too many odd shaped walls,
    nonaccurate window orientations, and missing elements), and b)
    autodesk is not consistent w/the gbxml file format across their
    platforms.  a revit architecture gbxml export was different in where
    space components were defined than a file from the autocad mep or
    revit mep packages and when architects i was working with upgraded
    from one year of revit to the next the gbxml file format would
    change.  this would require my rewriting sections of code to find
    the new space definitions w/their respective floors/walls/etc &
    i finally decided spending that much time rewriting something every
    i received a new gbxml file from a different client using a slightly
    different version of autodesk/archicad/bently wasn't worth it.  

my point?  i'm still creating shells & assigning zones via the
    wizard it is easier & faster than trying to convert something
    else.  odd shaped buildings = more shells.  buildings w/areas
    w/different heights = multiple shells.  get it as close as possible
    in the wizard mode & as long as it is thermodynamically similar
    it is not only  close enough it is closer than anything you'll
    produce with trane or hap as neither will give you a 3d
    representation of your building so you can make sure it is as close
    to thermodynamically similar as you can get.

and finally, i've also learned to use a master .pd2 file.  i add
    custom constructions (since 3.63 & up allow this) and custom
    windows and doors & then i don't have to define them every time
    i start a project.  floor slabs don't allow this yet but at least i
    have a master file with the baseline building constructions as
    predefined as possible & also has the common constructions i
    typically see from recurring clients.  note:  i still check the
    constructions when i switch to detailed mode just to make sure
    equest doesn't do something funny and change a calculated u-value to
    something else for some odd reason.

Though I was hoping to hear differently when opening this thread, I have to agree with the common opinion here, it’s still easier to create a model in eQuest. I’ve tried Ecotect and GreenBuilding Studio and the results have been the same, too much information in the BIM model, and the import either doesn’t happen or does not look at all like the building in question. 
  
One thing I have been trying, for very large projects, is to use Revit’s “Model Review” plug-in, in Revit MEP, to check the model before I export the XML. This tool is often pretty helpful, detecting glass types and rooms and other heat-transfer objects that will create errors. In a perfect world, the architects we work with should run this before they send us the model… because many of these errors have to do with the way they’re creating the architecture in Revit. 
  
One caveat that I have is that large models often have a lot of errors after “Model Review,” and time remedying them often is longer than just creating the model in eQuest. I too would like to hear how DrawBDL works, I’ve been thinking about purchasing it for some time now.

In my opinion this software is not ready for creating more complex models as I found creating the zones lacks the flexibility most models would need - The software will automatically create zones based on ASHRAE 90.1 perimeter set backs, 1 per floor, etc. Unless you have an open office plan, this is probably not what you need. You can define your zones manually, but not easily in my opinion. http://labs.autodesk.com/utilities/vasari/ - if you’re interested. 
  
I’ve tried to look into this a few times now, and all things considered it seems that importing 3D geometry is not that big of a timesaver compared to the design wizard, if at all. If anyone has experience with these workflows, I would be grateful to hear it.

hi  
 
Happy New Year to All. Does anybody know the any software from which we can import 3D model into eQuest.

I appreciate the comments that everyone has posted concerning this model importing issue.  There’s  been some great discussions revolving around what others have tried and the pitfalls that have been dealt with till now.  I had no idea about the translation issues with .gbxml.  This is good to know, as it always seems to pop up as the saving grace in model export/importing.  I do know from discussions with model developers that this issue is understood.  But like what Patrick stated, it makes since that the different software companies aren’t going to want its programs to be compatible with its competitors despite the demand that is obviously there.  (This thread is a great example.)   
  
I know that this has been a beneficial discussion for me, and hopefully beneficial to others.  I would appreciate any updates that teams run across in this effort to bridge the gap between the design model and the energy model.  It will only benefit our industry.

Though I was hoping to hear differently when opening this thread, I have to agree with the common opinion here, it’s still easier to create a model in eQuest. I’ve tried Ecotect and GreenBuilding Studio and the results have been the same, too much information in the BIM model, and the import either doesn’t happen or does not look at all like the building in question. 
  
One thing I have been trying, for very large projects, is to use Revit’s “Model Review” plug-in, in Revit MEP, to check the model before I export the XML. This tool is often pretty helpful, detecting glass types and rooms and other heat-transfer objects that will create errors. In a perfect world, the architects we work with should run this before they send us the model… because many of these errors have to do with the way they’re creating the architecture in Revit. 
  
One caveat that I have is that large models often have a lot of errors after “Model Review,” and time remedying them often is longer than just creating the model in eQuest. I too would like to hear how DrawBDL works, I’ve been thinking about purchasing it for some time now.

I like this conversation cause it is one that I have battled with for a long time. 
  
I’m going to respond on top of the previous comments in saying that it all depends on your comfort with software and 3D modeling. As below I agree with Vikram that at the moment it is easier to just model the project directly in eQuest and not import at all. Let me however tell you that I have built models in eQuest, Vasari, REVIT and Ecotect and they all work fine as long as you understand the basic principles of computer modeling. Vasari is definitely not ready for prime time however you can use it as your integrated modeler between eQuest and REVIT. 
  
The one main issue that I have run into and it is working as an architect and coordinating with our engineer that I have found out that architectural REVIT models with gbXML information looks totally different than the zoning model for an HVAC layout used in eQuest. The ways these models are constructed are total different even though the exterior skin might look the same. 
  
I’ve done this before but I have attached images of all the softwares to show the model. 
  
Just stick with the wizard for now unless the geometries are extremely complex. 
  
Thanks,

I agree. The argument is that with importing from Revit there is already a 3d model available. The issue normally is that there is too much information in the Revit model and most often it needs a LOT of clean up. Its potentially easy if you are a person with really fantastic model management skills (I haven’t met one yet).

One potential workflow is Revit > Ecotect > eQuest.  
  
If you google exporting Revit to Ecotect there are several videos / step by step instructions to show you what you need to do to prepare the model. It mainly has to do with how you define rooms, which become your thermal zones. However, Ecotect to eQuest I haven’t been able to do very successfully. There seems to be some problems with exporting the geometry and zones properly (which is really the major and some would say only benefit). The only thing I was able to import were wall constructions, which I would rather define in eQuest anyways. I haven’t been able to find a thorough explanation of what to do in Ecotect to prepare your geometry for eQuest. FYI, Ecotect also exports to gbXML, Energy Plus, Radiance, etc. 
  
Another workflow is Vasari > eQuest. Vasari is an, as of now, free Autodesk program in trial stages that is basically Revit combined with some basic DOE2 based energy modeling capability, really just for comparing different scenarios in early design.

Try looking at GreenspaceLIVE. This plugin for google sketchup for exporting gbXML file formats. The light weight plugin can rapidly decrease the time to draw geometry for use in multiple programs. I have exported files from here to eQuest, EnergyPro, Trace and EnergyPlus.  The tool is not without its flaws and we have been working to best understand the errors Autodesks GBS throws at us with the translation process to inp.
 
The big draw of this workflow model is the ability to push geometry to several tools and setup skill sets that can grow as energy modeling shifts to energyplus. The tool was free for a while but now has a monthly fee. 30 day trials are available though.

IBPSA-USA invites you to join us in Chicago
For our Winter 2012 meeting!
  4:00-9:00 PM, Saturday, January 21, 2012
Chicago, IL
 Parthenon Restaurant 
314 S. Halsted Street
Chicago, IL  60661 
312.726.2407
4:00 p.m. to 6:00 p.m.  IBPSA-USA Meeting (Agenda TBD – covering IBSPA-USA activities, state of the simulation industry, updates with standards, etc.) 
6:00 p.m. to 7:00 p.m.  Social Hour (Cash Bar)
7:00 p.m. to 9:00 p.m. Dinner and Presentation by John House, Ph.D., from Johnson Controls Canada 
 
Dinner meeting registration fee is $40, including family style Greek meal from Chicago’s famous Parthenon Restaurant, originator of flaming saganaki. Opa!
Cash bar is available during dinner as well.
We are working on an on-line advance registration option and will follow-up with that shortly for those who wish to pay with credit cards. In the meantime please RSVP to me by January 13th so that I can update the count with the restaurant. 
Better Building Controls Through Simulation
 
Simulation serves many roles in the building industry.  For many building professionals, simulation tools (e.g., EnergyPlus, DOE-2) are a means of comparing the energy performance of alternative envelope and HVAC system designs.  For individuals concerned with the development of control algorithms, these same tools are often inadequate because they lack dynamic system models that are necessary to properly design the algorithms.  This talk will present a number of use cases involving simulation tools and their application to the development of building control algorithms.  The talk will also touch on tools that can be used to streamline the process of testing a “simulation-proven” algorithm in a laboratory or field environment.    
 
Bio:  John House is a Principal Research Engineer at Johnson Controls Canada, where he conducts research on control algorithms and fault detection methods to improve the energy efficiency of heating, ventilating and air-conditioning systems in buildings.  Prior to joining Johnson Controls, he was employed first at the National Institute of Standards and Technology and later at the Iowa Energy Center.  John has a Ph.D. in mechanical engineering from the University of Iowa. 
The Parthenon has complimentary valet parking, and is relatively close to the UIC-Halsted stop of the CTA’s Blue Line public transportation ($2.25 each way) – take the Halsted street exit and not the Morgan Street exit at the station. In warmer weather the 1.2 mile walk might be pleasant from the Palmer House (allow 25 minutes – take a left on Monroe and a left on Halsted) – taxi cabs will be plentiful at the hotel and at the restaurant and might run about $5 each way. 
Please contact me with any questions related to the meeting. Feel free to come for the business meeting without an RSVP for dinner.

I have also struggled with this issue.  In addition to setting up complex geometry (pitched roofs, cathedral ceilings, floors that are partially underground, etc) one of the other challenges of the eQuest workflow is the requirement to re-define all custom windows if a zone line changes.  I actually wrote a SketchUp plugin to help me get geometry from Sketchup into eQuest (and EnergyPlus).  In eQuest, I also have the ability to set up space types with global parameters so that all "office" spaces are named "office" and their occupancy, lighting and equipment loads reference global parameters named "office_occ", "office_lpd" and "office_equip".  This way it's easy to make changes to large parts of the model when you're in detailed edit mode.

The Sketchup model is a dedicated model created for the energy model, but the geometry is MUCH easier to create in SU than in eQuest, and my export method creates a much cleaner inp file than the wizard.  If there are 5 floors, there is only one exterior wall construction type, and only one office_occ schedule. 

Sketchup geometry:  http://imgur.com/eQHWq 
eQuest geometry:  http://imgur.com/SU7oo 

If there is enough interest, I can clean up the script and make it available for a fee.  I spent too much time creating it to make it available for free.

Let me however tell you that I have built models in eQuest, Vasari, REVIT and Ecotect and they all work fine as long as you understand the basic principles of computer modeling. Vasari is definitely not ready for prime time however you can use it as your integrated modeler between eQuest and REVIT.

The ways these models are constructed are total different even though the exterior skin might look the same.

>I agree. The argument is that with importing from Revit there is already a 3d model available. The issue normally is that there is too much information in the Revit model and most often it needs a LOT of clean up. Its potentially easy if you are a person with really fantastic model management skills (I haven’t met one yet).

>If you google exporting Revit to Ecotect there are several videos / step by step instructions to show you what you need to do to prepare the model. It mainly has to do with how you define rooms, which become your thermal zones. However, Ecotect to eQuest I haven’t been able to do very successfully. There seems to be some problems with exporting the geometry and zones properly (which is really the major and some would say only benefit). The only thing I was able to import were wall constructions, which I would rather define in eQuest anyways. I haven’t been able to find a thorough explanation of what to do in Ecotect to prepare your geometry for eQuest. FYI, Ecotect also exports to gbXML, Energy Plus, Radiance, etc.

>Another workflow is Vasari > eQuest. Vasari is an, as of now, free Autodesk program in trial stages that is basically Revit combined with some basic DOE2 based energy modeling capability, really just for comparing different scenarios in early design. In my opinion this software is not ready for creating more complex models as I found creating the zones lacks the flexibility most models would need - The software will automatically create zones based on ASHRAE 90.1 perimeter set backs, 1 per floor, etc. Unless you have an open office plan, this is probably not what you need. You can define your zones manually, but not easily in my opinion. http://labs.autodesk.com/utilities/vasari/ - if you’re interested.

Hi Folks
Happy New year. Hope everyone had wonderful holidays.
I am in a process to get a custom weather file for energy model calibration for the MV process for LEED. I have  a custom weather file for the time span August 1st 2010 to July 31st 2011 and ran my energy model and getting weather file error. I have some questions regarding the properties of the weather file, 
 
1.     Does  the weather file need to start from Jan to Dec or can be a full year with starting and ending months different (in my case starting Aug 2010 to July 2011)?
2.     The .bin weather file, from the DOE website, size is 146kb and my custom .bin weather file size is 140kb, does the file size matter and how?
 
When I run energy model simulation with  the custom .bin file, the simulations runs till dec 17th and then fails and gives me a weather file error, I checked the .csv file I received with my custom file and ensured that data is present for all days. 
Any guidance or input is greatly appreciated, 
 
Thank you
