Building performance analysis with Revit

[jeffh]

Since I was one to vote yes on the poll I will be the one to make the first post here too.

If you are a user of Green Building Studio (or plan to be at some point) you might want to take a look at this white paper. It gives some tips and best practices for creating a Revit model to get good results out of Green Building Studio. Some of the steps to getting a good model might not necessarily be in your current workflow or thought process when modeling for construction documents. This document will cover some simple alterations you can make to your Revit model so you can achieve the best results.

The white paper can be downloaded from the following link. (Too big to attach here)

I see a paper about using IES and another one about Revit MEP. Am I missing something? I'd like to see a recent paper on GBS, especially since they have been annexed by Autodesk.

https://www.greenbuildingstudio.com/Tutorial.aspx says "the file is damaged and cannot be repaired."

The second paper at the link I listed is the one I am talking about. The methods used to get a robust model for analysis are the same if you are analyzing in IES or GBS.

I am not sure what is wrong with the link you posted at the GBS website.

Thanks for the info Jeff. I'm just curious to know how many people are actually using Revit with Green Building Studio? There doesn't seem to be many that I know of. I've used green building studio a few times and the information I got out of it was more than I was looking for. I hope to see more people using it in the future, and I hope to see Autodesk further develop the software.

The "Autodesk Revit® Architecture and Revit® MEP with GBS" link is broken.

I've tried unsuccessfuly to get anything out of GBS, everytime i create the gbxml file it says this file will most likely return meaningless results. I've tried with a single 1 room space with a floor and roof, still same message.

Perhaps some of the suggestions in this whitepaper can help return better results??? Some of the techniques in there are not things Architects would normally do when modeling a building for construction documents. With some slight modifications to the model/modeling techniques a better model for analysis can be created.

Volume calcs were on? You must turn on Volume calculation before you export gbXML.

I'm starting to look into which product from IES my company will buy. Looking through the white paper a couple questions came to mind. We are an Arch & Engineering firm and want to use some sort of energy analysis very early on and continue throughout the project.

1. It says plenum spaces should be created as seperate rooms. Does this mean the area above a dropped ceiling? It is my understanding that ceilings don't divide spaces when exported to gbXML. So I've been leaving the ceilings out of my test model. Will the analysis be better with ceilings and plenums taken into account? I imagine this reduces the conditioned space the VE toolkit or <VE> thinks there is.

If I do have a dropped ceiling and create a room for a plenum do I then have to create a ceiling level and a "ceiling" made out of the floor or roof tool?

2. When I create custom doors and windows what criteria does gbxml or IES's products use in determining what is glazing vs solid. Is it based on the transparency of the material or the subcategory?

i have the same problem as WS my template file keeps returning the same error
