I just wanted to know, how people map windows? When importing a model from Revit using generic windows, the materials included in a window often looks like this:
When I look at windows from the material library, it looks like a window includes both insulated glazing units (IGUs), frames, etc., and that the declared unit is m2.
I would be tempted to drop the window (VELFAC 200 Energy in this case) on my building component type, like illustrated below, but that would be wrong, right?
What is the proper way to do this?
My own conclusion so for is that you can only use full window assemblies, like this example from VELFAC, for simple models/sketches, where windows is one single surface without frames, etc., but please correct my, if there’s something I’m not seeing.
NB!
As vindues include multiple materials, shouldn’t they be placed under Construction instead of Material?
I’m running into the same problem with windows and doors.
My solution was to deactivate every material in fx a window and then adding a custom material with the area of the total window and assigning a product epd, like the one from Velfac.
The problem is that whenever you reload the Revit model into RTLCA, the assigned value stays the same, if you added more windows these wont be registered.
I’m guessing we aren’t the only people having trouble with this. A specific solution would need to be programmed, to only gather the area of the window, not the area of materials in the window, and making the area of windows linked to the Revit model when reloading after changes.
For now, my solution is never to use any of the windows, as they will be applied incorrectly. So now I only use glazings and frames separately. Unfortunately, this means that I’m not able to use productspecific EPD’s.
