6.1.4.18.1 Semantic definition

Shading device properties associated with an element that represents a shading device

6.1.4.18.2 Applicable entities

6.1.4.18.3 Properties

Name Property Type Data Type Description
Reference IfcPropertySingleValue IfcIdentifier

Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.

Status IfcPropertyEnumeratedValue PEnum_ElementStatus

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).

ShadingDeviceType IfcPropertyEnumeratedValue PEnum_ElementShading

Specifies the type of shading device.

MechanicalOperated IfcPropertySingleValue IfcBoolean

Indication whether the element is operated machanically (TRUE) or not, i.e. manually (FALSE).

SolarTransmittance IfcPropertySingleValue IfcNormalisedRatioMeasure

The ratio of incident solar radiation that directly passes through a system (also named 蟿e). Note the following equation Asol + Rsol + Tsol = 1

SolarReflectance IfcPropertySingleValue IfcNormalisedRatioMeasure

(Rsol): The ratio of incident solar radiation that is reflected by a glazing system (also named 蟻e). Note the following equation Asol + Rsol + Tsol = 1

VisibleLightTransmittance IfcPropertySingleValue IfcNormalisedRatioMeasure

Fraction of the visible light that passes the object at normal incidence. It is a value without unit.

VisibleLightReflectance IfcPropertySingleValue IfcNormalisedRatioMeasure

Fraction of the visible light that is reflected by the glazing at normal incidence. It is a value without unit.

ThermalTransmittance IfcPropertySingleValue IfcThermalTransmittanceMeasure

Thermal transmittance coefficient (U-Value) of an element, within the direction of the thermal flow (including all materials).

Thermal transmittance coefficient (U-Value) of a material of a certain thickness for this element.

IsExternal IfcPropertySingleValue IfcBoolean

Indication whether the element is designed for use in the exterior (TRUE) or not (FALSE). If (TRUE) it is an external element and faces the outside of the building.

Roughness IfcPropertySingleValue IfcLabel

A measure of the vertical deviations of the surface.

SurfaceColour IfcPropertySingleValue IfcLabel

No description available.
