Problems between Revit and OpenStudio

Hi everyone !

I am working on the exportation of a revit model into Openstudio and I have some problems :

  • First, although the information is in the gbXML file, OpenStudio don't seem to recognize the location of my building.
  • Second, the field [Construction Name] is blank for my windows. I find the material in the gbXML file but not in OS.
  • Finaly, there are also in my gbXML file the schedule, the number of people, etc, but OS does not read them.

So if someone can help my with those problems, it would be great. Maybe those are identified issues and the development team is currently working on it but I have to know if I can fix it now or not. Thanks!

Here is a list of what is supported with gbXML import. It appears that currently, building location and load definitions are not supported.

The subsurface construction name not being assigned was a known bugthat has been fixed (see also: Which version of OpenStudio are you using?

I'm using OS 1.11.0. Yes I saw that this bug has been fixed in the new version but, with my model, it works for the doors and not with the windows.

It seems that OS does not import WindowType and its proprieties. There is no material for the windows.

@PY, the logic doesn't support the translation of WindowTypes at the moment and thus WindowTypeIdRefs either. In your gbXML if you change all windowTypeIdRef to constructionIdRef and change <windowtype> to <construction> then it will work. It's not ideal, but its a fix you can do with a global find and replace very quickly.

Thanks for the answer. I tried it however there is still a problem : OS got the Construction from the gbxml file but there is no layer. So when I ran it there was a severe error : * Severe * IP: IDF line~3207 Object=CONSTRUCTION, name=AIM0995, Required Field=[Outside Layer] was blank.

@PY, that means you need to add material definitions to you construction. The construction has been assigned to all the subsurfaces, but now materials need to be added to the construction for it to have relevant properties at run time.
