Definition

Fraction of incident solar electromagnetic radiation that enters a building through a complete window or glazing assembly and is converted to interior heat gain, expressed as a dimensionless number between 0 and 1; the metric accounts for both directly transmitted solar radiation and solar energy absorbed by the glazing and later emitted or conducted inward.
