WebDec 28, 2024 · The solar heat gain coefficient (SHGC) refers to the ratio of solar heat penetrating through windows compared to the solar energy reaching the window per unit area in a given incident angle and environmental conditions (indoor temperature, outdoor air temperature, wind speed, and insolation). The SHGC can be expressed via the following … WebSolar heat gain. The solar heat gain coefficient (SHGC) for windows (expressed as SHGCw) measures how readily heat from direct sunlight flows through a whole window (glass and frame together). SHGC is expressed as a number between 0 and 1. The lower a window’s SHGC, the less solar heat it transmits to the house interior.

WebApr 23, 2024 · It is defined as the ratio of solar radiation at a given wavelength and angle of incidence passing through a glass unit to the radiation that would pass through a reference window of frameless 3 millimeters (0.12 in) clear Float Glass.
