Solar Heat Gain Coefficient (SHGC): While not required for windows in Climate Zone 7, the SHGC is still required data for Manual J calculations. SHGC should be taken directly from the sticker on the glass. If not known, either use default as per Table 102.1.3(3) of the 2009 IECC or equation SHGC equals 0.87 multiplied by the Shading Coefficient under19-23 of Manual J.
Altitude Correction Factor (ACF): Site-specific to elevation
Wind Velocity Values: 15 miles per hour for Heating and 7.5 miles per hour for Cooling
