Re: [EnergyPlus_Support] Windows construction

[fred buhl <wfbuhl@xxxxxxx>]

You need to construct a layer-by-layer description of a window and 
fiddle with
the inputs to get close to your desired U-factor, SHGC and visible 
transmittance.
If you don't want to undertake that daunting task you can look in 
WindowConstructs.idf
and find the closest window construction.
