WebOct 7, 2024 · What is solar heat gain in windows? Solar heat gain coefficient (SHGC) is the fraction of solar radiation admitted through a window, door, or skylight — either transmitted directly and/or absorbed, and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater its shading ability. WebIn the cooling/heating loads simulation for buildings, it is too difficult to estimate the solar heat gain through the windows with shading devices using the detailed and complicated calculation method (e.g. JIS A 2103) and the off-normal optical characteristic parameters in each time.
