[Bldg-sim] eQuest Modeling of Film on top of Glass

[Sami, Vikram]

Have you tried creating the assembly in LBNL's Window /Optic?
You might need to build a glass type in optic and then use it in a glazing assembly in Window.

Subject: [Bldg-sim] eQuest Modeling of Film on top of Glass

Okay, Smart peoples:

I have an existing glass (say Solar Bronze) which has properties of SHGC, VT, and U-Value. I now wish to take this same glass and add a film on top of it to further enhance the SHGC and VT properties.

I cannot just take a diferent window from the Glass Library, because I do not know the additive SHGC and VT effects.  Is there any way to do a "glass-layers" operation? Or must I just guess at a glass that MIGHT be the equivalent?

Thanks.
