VisibleLightReflectance
Property description
Fraction of the visible light that is reflected by the glazing at normal incidence. It is a value without unit.
0.
VisibleLightTransmittance
Property description
Fraction of the visible light that passes the glazing at normal incidence. It is a value without unit.
0.
SolarAbsorption
Property description
(Asol) The ratio of incident solar radiation that is absorbed by a glazing system. It is the sum of the absorption distributed to the exterior (a) and to the interior (qi). Note the following equation Asol + Rsol + Tsol = 1
0.
SolarReflectance
Property description
(Rsol): The ratio of incident solar radiation that is reflected by a glazing system (also named ρe). Note the following equation Asol + Rsol + Tsol = 1
0.
SolarTransmittance
Property description
(Tsol): The ratio of incident solar radiation that directly passes through a glazing system (also named τe). Note the following equation Asol + Rsol + Tsol = 1
0.
SolarHeatGainTransmittance
Property description
(SHGC): The ratio of incident solar radiation that contributes to the heat gain of the interior, it is the solar radiation that directly passes (Tsol or τe) plus the part of the absorbed radiation that is distributed to the interior (qi). The SHGC is refered to also as g-value (g = τe + qi).
0.
ShadingCoefficient
Property description
(SC): The measure of the ability of a glazing to transmit solar heat, relative to that ability for 3 mm (1/8-inch) clear, double-strength, single glass. Shading coefficient is being phased out in favor of the solar heat gain coefficient (SHGC), and is approximately equal to the SHGC multiplied by 1.15. The shading coefficient is expressed as a number without units between 0 and 1.
0.
ThermalTransmittanceSummer
Property description
Thermal transmittance coefficient (U-Value) of a material. Summer thermal transmittance coefficient of the glazing only, often referred to as (U-value).
0.
ThermalTransmittanceWinter
Property description
Thermal transmittance coefficient (U-Value) of a material. Winter thermal transmittance coefficient of the glazing only, often referred to as (U-value).
