[Equest-users] Modeling regular curtain wall systems

[Mark Darrall]

Hi!

What's the best way to input a curtain wall system to allow for the repetitive vertical mullions? I can calculate system U factor based on the area of vision glass : overall area, but I don't see a way to input that directly...unless:

If the vertical mullions are already captured in the system U factor can I just ignore it and treat it like one huge picture window? So at FRAME-WIDTH I would just enter the width and properties of the perimeter frame and then at GLASS-CONDUCTANCE enter the corrected U-factor for the system?

I did search this in onebuilding.org, but didn't see it addressed.

Thanks!
