[bldg-sim] Green Building Studio

[Mohit Mehta]

Good dialogue!

Out of curiosity - we actually tried this GBS website – all we did was open the Revit file (of one of our projects), exported to GBXML and load it into the geopraxis site. Took all of 10-15 min. The site asks some basic information about location, project statistics, and energy statistics (you can enter your own or go with their database of energy costs based on your zip code) and ran their report. All pretty straightforward.  The project architect (from the design team) input this himself and forwarded the output to me for feedback.

The output that we got was not up to par (aware that it depends on what/how it was input in the first place). Some quick basic observations on the output summary - 

*	The annual electric/fuel breakdown was missing quite a few categories. 
*	I am not sure what or how the schedules are input for this building. It never asked for that input. 
*	The envelope/glazing interpretations were suspect
*	The cooling load was way off (on the high side)  

The information on the report is a starting point but I am not sure who this report is exactly meant for. Is it for the architect to interpret and make changes or is it for the engineer/modeler who interprets the report and gives his feedback to the architect to make the necessary changes? There is a lot missing from the process of defining, inputting and getting a legitimate output that can be troubleshot if something looks amiss, to feel very confident about it. I mean, even in the most accurate of models there is a +-5-15% error margin, if not more. In this a lot was unclear to me. It saved us some time but are we willing to make design/mechanical changes based on it? Personally, I am more comfortable if the process is under my control where I can tweak the various inputs and directly see the impacts that they might have. And I am sure most of us in this ‘group’ feel the same.

We will be looking at it more in depth soon.

My two cents – Happy Holidays

Have bldg-sim users seen this yet (sounds too good to be true): 

Teams use their existing computer-aided design systems to communicate a project's building geometry to the GBS website, which conducts an energy analysis of the building design. The program enables the design team to look at the energy impact of early design decisions, compare alternatives, and share information more broadly with other team members.

It provides whole building energy analysis using the widely accepted building analysis program, DOE-2, at no charge to the design team. GBS is accessed from within the design team’s 3D-CAD software.
