Solar heat gain coefficient
The definition of SHGC on this page is incomplete as it does not indicate whether the input gain is global (direct + indirect) or just direct, and it does not give the sun angle.
CORRECTION - Actual solar heat gain is dependent on the angle of incidence of solar radiation on the glazing (and so the proportion of diffuse and direct beam solar radiation) as well as the spectral make up of the solar radiation. However, as a simplified method, manufacturers will often only provide a spectrally-averaged solar heat gain coefficient for normally-incident solar radiation. Values for other angles of incidence and for diffuse solar radiation can then be estimated using standard equations or tables for similar windows.
