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. 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 …
WebMar 25, 2024 · In the top right corner of the label under Energy Performance Ratings, you’ll see a number between 0-1. That’s the Solar Heat Gain Coefficient (or SHGC Factor). This number measures the amount of solar heat that reaches a window against the amount of heat that filters through to the inside. The best rating for your home is determined by the ...

WebOct 19, 2024 · A low E coating in combination with a tint is often referred to as “solar glass”, and can have a solar heat gain coefficient (g-value) of as low as 0.14 – meaning 86% of solar thermal energy is reflected away from your home. Thus, creating a cool, comfortable indoor summer environment – another of the big advantages of low E glass. WebIn subtropical Hong Kong, solar heat through fenestration, particularly on vertical surfaces, plays a major role in determining the thermal performance of a building.
