Window Assembly Solar Heat Gain Estimator

Combine window area, SHGC ratings, and solar orientation radiation to estimate glazing cooling loads.

Glazing Heat Gain Equation:

$ Q_{\text{glazing}} = A_{\text{win}} \times \left[ (U \times \Delta T) + (\text{SHGC} \times E_{\text{solar}} \times F_{\text{shading}}) \right] $
