Web4.1 The ETTV takes into account the three basic components of heat gain through the external walls and windows of a building. These are: heat conduction through opaque … Weba SHGC, or Solar Heat Gain Coefficient, is a measure of the solar radiation admitted through a window. SHGC ranges between 0 and 1; the lower the number, the lower the transmission of solar heat. SHGC has replaced shading coefficient (SC) as the standard indicator of a window's shading ability. SHGC is approximately equal to the SC multiplied ...
