Solar heat gain coefficient means

WebThe solar heat coefficient is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed and subsequently released inward. The solar heat gain coefficient is expressed in a number between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits. WebSolar Heat Gain Coefficient (SHGC) measures the fraction of solar energy transmitted and tells you how well the product blocks heat caused by sunlight. SHGC is measured on a scale of 0 to 1; values typically range from 0.25 to 0.80. The lower the SHGC, the less solar heat the window transmits. (EPA requires that the SHGC for ENERGY STAR labeled ...
