Set Shading

Overview

Describes the setting (capture) of information about shading applied to building elements including the type pof shading, azimuth and inclination, tilt, solar transmittance and other related factors.

Results

Shading values are captured

Description	Entity/Pset/Functional Part	MAN	REC	OPT
Specify the type of shading device to be used	Pset_ElementShading.ShadingDeviceType::IfcPropertyEnumeratedValue::PEnum_ElementShading
Set the azimuth of the element as derived from the placement of the element shape. For glazing elements, reflectivity, transmissivity, absorptivity values, by convention: North = 0' and measurement is done clockwise (I.e. east = 90', if unit is grad).	Pset_ElementShading.Azimuth::IfcPropertySingleValue::IfcPositivePlaneAngleMeasure
Set the inclination of the element as derived from the placement of the element shape, By convention: vertical = 0', horizontal = 90'.	Pset_ElementShading.Inclination::IfcPropertySingleValue::IfcPositivePlaneAngleMeasure
Set the minimum and maximum angles of possible tilt defined in the plane perpendicular to the extrusion axis (X-Axis of the local placement). The angle shall be measured from the orientation of the Z-Axis in the local placement.	Pset_ElementShading.TiltAngle::IfcPropertyBoundedValue::IfcPlaneAngleMeasure
Set the overall or average ratio of the solar flux transmitted through a body to that incident upon it.	Pset_ElementShading.AverageSolarTransmittance::IfcPropertySingleValue::IfcPositiveRatioMeasure
Set the overall or average ratio of the visible spectral flux transmitted through a body to that incident upon it	Pset_ElementShading.AverageVisibleTransmittance::IfcPropertySingleValue::IfcPositiveRatioMeasure
Set the ratio of reflected power to incident power	Pset_ElementShading.Reflectance::IfcPropertySingleValue::IfcPositiveRatioMeasure
Set the roughness of the surface as measured by the vertical deviations of the surface	Pset_ElementShading.Roughness::IfcPropertySingleValue::IfcPositiveLengthMeasure
Set the color of the surface	Pset_ElementShading.Color::IfcPropertySingleValue::IfcLabel
