LEED energy Analysis using a gbXML file from Revit  
Does anyone have any workflows they are doing for exdivorting a Revit model to gbXML and using that information to do LEED credit Energy Modeling.
I have looked at IES Virtual Environment, and we are getting a workflow sdivecific demo on Friday. 
 
I have also looked at eQuest, but there is not direct imdivort from gbXML into eQuest. The only way I was able to do it, was to submit the model to Autodesk Green Building Studio, and then download the Doe2 file that can be used in eQuest from there. eQuest, although it seems like you could do everything you need to once you have the model in there, it also seems the interodiverability is very divoor, in that I really can’t use the data anywhere else, and I also assume that if I try to reimdivort a new model, I have to do all of my assignments (wall, glazing tydives, HVAC sdivecs, etc.)
 
Does anyone have any exdiverience with a workflow that works best with Revit, in their odivinion?

Okay everyone, I wanted to give an update on what I have figured out for this workflow so far:
 
1)      There are a ton of ways to do this…currently our MEP consultant for Energy Analysis using the eQuest program.
a.       The only way I have found to get a model from Revit into eQuest is to export a gbXML file from Revit, take that into Autodesk Green Building Studio, and then export a Doe2 file from Green Building Studio that can then be imported into eQuest. Doing this, however, causes limited functionality in eQuest, as you lose the ability to use the built in wizards, i.e., everything has to be set manually without the wizards, as far as I gathered.
2)      Ecotect seems to have a promising feature, and does a lot of good stuff, but I have heard that it may lack some in the area of Energy Analysis/Simulation, as it pertains to the LEED credit.
3)      IES Virtual Environment seems very promises, but it’s expensive. Also, it is my understanding that IES cannot export it’s data out to any other useable file types for use in, say, eQuest or Ecotect, therefore, to establish a valid workflow with our consultants, we would need them to buy into the software (however, they did say there might be a chance to be able to export to gbXML in version 6.1 which is supposed to hit the streets soon). It is, however, very robust, and is about to come out with what they are calling a PRM Navigator for the LEED EA 8.1 credit, using the VE-GAIA framework. It also has plugins for Revit that allow you to do early analysis without leaving Revit, which is really nice.
 
The majority of my specific program research has been with IES Virtual Environment, and here are few other things that I found out.
 
1)      The PRM Navigator for VE-GAIA software will come with (this is my understanding) the baseline defaults based on ASHRAE 90.1-2007.
2)      The program may have the capability to be multi-threaded, in that it could run multiple simulations at the same time (all your orientations (N,S,E,W) for example).
 
I may post more related to this soon, when I have figured out some more stuff. I’d love to hear anybody else’s thoughts on this!

 any further updates on this? I would really like to know more on how IES VE fairs as a whole building energy simulator vs Equest.

Well, the PRM navigator for LEED is out now...I haven't seen it in action yet, and we still haven't taken the plunge to invest the time and money to doing the Energy Models ourselves, so I don't really have much more specific information.

From what I understand, IES uses methods that line up with ASHRAE codes for modeling software, and there is so much more you can do with IES than with eQuest, specifically in terms of visual environment in relation to modeling the building, and the ability to easily export or bring other file types in to run energy analysis on.

That's all I got for now...
