Cooling load due to solar heat gains Glazing
Q = A (SC) (SHGF) (CLF)
A= glass area
SC= shading coefficient
SHGF= solar heat gain factor, tabulated by ASHRAE
CLF= cooling load factor, tabulated by ASHRAE
Q = U x A x CLTD
U= surface U-factor
A= surface area
CLTD= cooling load temperature difference
SC(shading coefficient)

The SC is the ratio of solar gain (due to direct sunlight) passing through a glass unit to the solar energy which passes through 3mm Clear Float Glass.
It is referred to as an indicator to how the glass is thermally insulating (shading) the interior when there is direct sunlight on the panel or window.
