Solar heat gain coefficient. A numerical expression between 0 and 1 expressing the performance of glass in transferring heat.

Solar Heat Gain Coefficient. 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 without units between 0 and 1. A window with a lower Solar Heat Gain Coefficient transmits less solar heat, and provides better shading. Spectrally Selective Glazing: A specially engineered low-E coated or tinted glazing that blocks out much of the sun's heat while transmitting substantial daylight.

Solar Heat Gain Coefficient. The solar heat gain coefficient, also called a shading coefficient, is a measure of how well a window absorbs or reflects heat from the sun. The lower the coefficient, the better the window is at blocking the sun's heat. Windows in hot or temperate climates should have a low SHGC; south-facing windows in cold climates should have a high SHGC.

Solar Heat Gain Coefficient. Solar heat gain coefficient (SHGC) is the glazing's effectiveness in rejecting solar heat gain. SHGC is part of a system for rating window performance used by the National Fenestration Rating Council (NFRC). SHGC is gradually replacing the older index, shading coefficient (SC), in product literature and design standards. If you are using glass whose performance is listed in terms of SC, you may convert to SHGC by multiplying the SC value by 0.87.

Solar heat gain coefficient. A measure of the total solar energy transmittance entering a building through the glazing as heat gain. It is the total heat transmission of direct solar transmission and that proportion of absorbed radiation that is reradiated into the building from the action of heat absorbing glass. The lower the solar heat gain coefficient the better the glass control heat energy transmission. The shading coefficient is derived from the solar heat gain coefficient.

Solar Heat Gain Coefficient. SHGC measures how well a product blocks heat caused by sunlight. The lower the window's solar heat gain coefficient, the less solar heat it transmits.

Solar Heat Gain Coefficient. 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 windowâ€(tm)s shading ability. It is expressed as a number between 0 and 1. The lower a windowâ€(tm)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. The fraction of total solar energy that enters a space through a window. The total solar gain through a windows equals the SHGC multiplied by the incident solar radiation. The Shading Coefficient (SC) is referenced frequently and equals the SHGC for a windows divided by 0.87 (assuming normal incidence).

Solar Heat Gain Coefficient. The portion of directly transmitted and absorbed solar energy that enters into the building's interior. The higher the SHGC, the higher the heat gain.

Solar heat gain coefficient. A rating, which is now generally replacing shading coefficient, measuring a window's ability to transmit solar heat. It measures both the solar radiation which is directly transmitted, as well as the solar radiation absorbed by the glass and subsequently transmitted. The lower a unit's solar heat gain coefficient, the less solar heat it transmits, and the greater is its shading ability. It is approximately equal to the the shading coefficient divided by 1.15. It is expressed as a number without units between 0 and 1.

Solar Heat Gain Coefficient. Solar heat gain coefficient is a measurement of the amount of solar radiation through a piece of glass or door material. The lower the SHGC, the fewer UV rays that cause heat gain come through the glass.
