Name Type Description
VisibleTransmittance P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Visible Transmittance Transmittance at normal incidence (visible). Defines the fraction of the visible spectrum of solar radiation that passes through per unit area, perpendicular to the surface.
SolarTransmittance P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Solar Transmittance Transmittance at normal incidence (solar). Defines the fraction of solar radiation that passes through per unit area, perpendicular to the surface.
ThermalIrTransmittance P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Thermal Ir Transmittance Thermal IR transmittance at normal incidence. Defines the fraction of thermal energy that passes through per unit area, perpendicular to the surface.
ThermalIrEmissivityBack P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Thermal Ir Emissivity Back Thermal IR emissivity: back side. Defines the fraction of thermal energy emitted per unit area to "blackbody" at the same temperature, through the "back" side of the material.
ThermalIrEmissivityFront P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Thermal Ir Emissivity Front Thermal IR emissivity: front side. Defines the fraction of thermal energy emitted per unit area to "blackbody" at the same temperature, through the "front" side of the material.
VisibleReflectanceBack P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Visible Reflectance Back Reflectance at normal incidence (visible): back side. Defines the fraction of the solar ray in the visible spectrum that is reflected and not transmitted when the ray passes from one medium into another, at the "back" side of the other material, perpendicular to the surface. Dependent on material and surface characteristics.
VisibleReflectanceFront P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Visible Reflectance Front Reflectance at normal incidence (visible): front side. Defines the fraction of the solar ray in the visible spectrum that is reflected and not transmitted when the ray passes from one medium into another, at the "front" side of the other material, perpendicular to the surface. Dependent on material and surface characteristics.
SolarReflectanceBack P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Solar Reflectance Back Reflectance at normal incidence (solar): back side. Defines the fraction of the solar ray that is reflected and not transmitted when the ray passes from one medium into another, at the "back" side of the other material, perpendicular to the surface. Dependent on material and surface characteristics.
SolarReflectanceFront P_SINGLEVALUE / IfcPositiveRatioMeasure
Pset_MaterialOptical Solar Reflectance Front Reflectance at normal incidence (solar): front side. Defines the fraction of the solar ray that is reflected and not transmitted when the ray passes from one medium into another, at the "front" side of the other material, perpendicular to the surface. Dependent on material and surface characteristics.
