[Bldg-sim] Frameless Windows

[David Eldridge]

I’d be a little skeptical that there wasn’t any edge effect taking place in
the actual building windows, whether due to frame or other method of
connection to the building envelope.

I'm simulating a retail building for LEED submission and I would like to ask
if it is correct that since these has no frames, assembly U value and SHGC
will be equal to the center of glass u-values. Is this correct?



Many thanks!
