Solar heat gain through windows

WebJan 8, 2024 · Solar heat gain coefficient Solar heat gain coefficient (SHGC) measures how well a window and film combination blocks heat from sunlight. The SHGC is the amount of solar heat that enters through the window/film combination, expressed as a number from 0 to 1. The lower the SHGC, the less solar heat is transmitted. Solar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit … See more Solar gain is most frequently addressed in the design and selection of windows and doors.
