It becomes less significant in situations where direct sunlight is not a major factor (e.g., windows completely shaded by overhangs). Window design methods have moved away from Shading Coefficient to Solar Heat Gain Coefficient (SHGC), which is defined as the fraction of incident solar radiation that actually enters a building through the ...
The shading coefficient (SC) is a measure of the radiative thermal performance of a glass unit (panel or window) in a building.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 millimetres (0.12 in) Clear Float Glass.

The SC, or shading coefficient, is used widely in the evaluation of heat gain through glass and windows. [1] [5] Finally, the SCL, or solar cooling load factor, accounts for the variables associated with solar heat load. These include the global coordinates of the site and the size of the structure.

A window with insulating glass is commonly known as double glazing or a double-paned window, ... (R-value) and the Solar Heat Gain Coefficient (SHGC). Two types of ...
SHGC–Solar Heat Gain Coefficient: measures the assembly's transfer of heat from outside to inside that is caused by sunlight. These properties are labeled in the U.S. as a decimal between zero and one, with lower numbers indicating lower heat transfer rates. Depending on the geographic region, optimal U-factor and SHGC performance will vary.
A window is an opening in a wall, door, ... Solar heat gain coefficient (SHGC), ratio of solar heat (infrared) passing through the glass to incident solar heat;
Shortly before the 2019 NBA draft, the New Orleans Pelicans finally worked out a way to trade disgruntled star Anthony Davis. After the Pelicans won the draft lottery to get the No. 1 overall pick ...
The organization was founded in 1989 [2] by a group of window and door industry professionals in response to mounting pressure from local and national governments to standardize energy efficiency ratings for windows and doors. Before NFRC standardized energy efficiency ratings, each manufacturer developed their own methods.
