The SHGC is the measurement of how much radiant heat, or heat produced by the sun, comes in through a window. Similar to U-Factor, the lower the SHGC, the lower the radiant heat transmitting through the window. As indicated in the chart below, the EPA …
WebSolar Transmittance and Solar Reflectance. Solar transmittance (τe) and solar reflectance (ρe) refer to the ratio of the radiant flux of solar energy vertically incident on a glass surface to the transmitted radiant flux or reflected radiant flux. These values are calculated by equations (3) and (4) below, using spectral transmittance (τ (λ ...

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. WebFeb 27, 2024 · What is Solar Heat Gain? At its most basic, solar heat gain is the heat transferred from the sun’s rays. Solar Heat Gain Coefficient “is the fraction of solar radiation admitted through a window, door, skylight—either transmitted directly and or absorbed/conducted, and subsequently released as heat inside the home. The lower …
WebE) Solar Heat Gain Coefficient (SHGC). F) Visible Transmittance (VT). It includes the solar heat gain coefficient (SHGC) and visible transmittance (VT) of the window film, both numbers between 0 and 1. The lower the SHGC, the better the film is at blocking heat gain. The higher the VT, the more potential for daylighting.
