Questions of Energy Analysis with green building studio in Revit

[aurelieL32JD]

Good afternoon,

I am trying to use Revit transfer to Green Building Studio and Insight 360 for analysis. I have to main questions.

1/ With the same file sent to GBS and Insight 360, the 'BIM' baseline presented via Insight 360 is supposed to be the same as the data I can check under in GBS under "Building details and assumptions" (eg. for thermal properties of the walls) right? The reason I am asking this is that under Insight 360, wall construction R value can't be checked, it just says 'as modeled' value, and as savings are shown when changing for 'R2 cMU' it would mean that Insight 360 considers a R value from the baseline as being below R2 CMU which is not the case as you can see on the screenshot form GBS below.

2/ A file is indeed sent to GBS and Insight 360 and I'd like to make sure that areas are properly transferred and understood. Attached is the gbxml file transferred and saved from GBS. I am confused by the huge amount of 'air openings' I can read in GBS under "Building details and assumptions" as when I check the file via Revit/3d view energy model/ analytical surfaces/ air openings, I don't see this amount at all...

thanks a lot in advance for your help, 

Regards

Aurelie

Hi Aurelie,

You are correct that you can check the BIM settings used in Insight in the Base Run in GBS.

There are many thermal properties that factor into the energy efficiency of a building material. The description of the wall construction "R2 CMU" refers to the r-value of the insulation (R-2) only and not the total u-factor of the entire wall assembly.

1. How was your model created?
2. Was it originally created in FormIt?
3. Was it created in Revit as a mass model?
4. Are you seeing the expected floor area in GBS Classic?
5. Can you send us the Revit model?

Good morning,

thanks for your answers,, below are my answers and questions

1. How was your model created?  in Revit
2. Was it originally created in FormIt? no 
3. Was it created in Revit as a mass model? no I don't think so
4. Are you seeing the expected floor area in GBS Classic? yes for the floor areas
5. Can you send us the Revit model? yes I can, shall I send it to insight360.support@autodesk.com ?  which file format do you need?

Regards,

Aurelie

please send the .rvt file & let us know what version of Revit was used to create it.

I am trying to send those but they are 43MB so not sure if you received a link to download those?

you should be able to upload your model here:

Hi Aurelie,

One of the people on our team took a look at your model and has some tips for you.

First of all, in order to create an energy model from a detailed architectural read and apply this section of the Revit help.

http://help.autodesk.com/view/RVT/2017/ENU/?guid=GUID-32BD5A12-DF5B-4B51-B51A-D799C729A78A

You can also create massing or ‘mixed’ models quickly specially for energy analysis which is often easier and more informative, see:

http://help.autodesk.com/view/RVT/2017/ENU/?guid=GUID-A77EF18D-0EB8-47D3-A653-6370D9F1374A

Beyond that some other tips:

• If possible upgrade to 2017
• The object styles in the model are corrupt so the EAM (Energy Analytical Model) doesn’t appear properly, follow these steps:

o   Create a new project using the Architecture template

o   Open the model architecture 2017

o   On the Manage tab click the tool Transfer Project Standards

o   Click “Check None”, then check “Object styles” > OK > click “Overwrite”

o   >> Colors should update.

• In energy settings change mode to conceptual and building element’ also this model uses phases so set the energy setting h=phase to CP02-CFEI

He also found an 8”/4” resolution and found a small gaps in the basement. See the attached screenshot.

Let us know if you have more questions on this topic, otherwise please accept as a solution so that others can benefit from this information.
