The solar energy transmitted through a glazing plus the portion of solar radiation that is absorbed and either convected or reradiated toward the interior.
Heat from solar radiation that enters a building.
The amount of heat that a structure gains through the glazing surface.
The fraction of solar radiation admitted through a window or skylight, both directly transmitted and absorbed and subsequently released inward. The solar heat gain coefficient has replaced the shading coefficient as the standard indicator of a window's shading ability. It is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits and the greater its shading ability. SHGC can be expressed in terms of the glass alone or can refer to the entire window assembly.
Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed, then subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window's SHGC, the less solar heat it transmits.
Coefficient Measures the amount of radiant heat transfer from the sun through a window. The lower the number means the less amount of solar heat transfer through the window (lower is better in the south). CT (SHGC). Measures the amount of radiant Systems SHGC = .27, this equates to a 48% thermal
Solar radiant heat, transmitted or re-emitted by glazing into a building, contributing to the build-up of heat.
The amount per hour of solar heat coming through a square foot of glass. Measured in units of Btu/hr/sq. ft.
Heat added to a space due to transmitted and absorbed solar energy.
The percentage of heat gained from both direct sunlight and absorbed heat. The smaller the number, the greater the ability to reduce solar heat gain.
