Kevin,<br><br>DOE-2's glass library contains output from LBL's window software. It takes into account the incident angle dependency of solar heat  gain and visible light transmittance, which is superior to using the simplified input method.
<br><br>If you don't find the glazing you want in the DOE-2 glass library, you could import results from Window software.<br><br><br>Ramana Koti, LEED AP<br>Sustainable Building Analyst<br><br>ELEMENTS | a division of berkebile nelson immenschuh mcdowell architects
