6.1.4.24.3 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).

AcousticRating IfcPropertySingleValue IfcLabel

Acoustic rating for this object. It is provided according to the national building code. It indicates the sound transmission resistance of this object by an index ratio (instead of providing full sound absorption values).

FireRating IfcPropertySingleValue IfcLabel

Fire rating for this object. It is given according to the national fire safety classification.

SecurityRating IfcPropertySingleValue IfcLabel

Index based rating system indicating security level. It is giving according to the national building code.

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.

Infiltration IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Infiltration flowrate of outside air for the filler object based on the area of the filler object at a pressure level of 50 Pascals. It shall be used, if the length of all joints is unknown.

ThermalTransmittance IfcPropertySingleValue IfcThermalTransmittanceMeasure

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

GlazingAreaFraction IfcPropertySingleValue IfcPositiveRatioMeasure

Fraction of the glazing area relative to the total area of the filling element. It shall be used, if the glazing area is not given separately for all panels within the filling element.

HasSillExternal IfcPropertySingleValue IfcBoolean

Indication whether the window opening has an external sill (TRUE) or not (FALSE).

HasSillInternal IfcPropertySingleValue IfcBoolean

Indication whether the window opening has an internal sill (TRUE) or not (FALSE).

HasDrive IfcPropertySingleValue IfcBoolean

Indication whether this object has an automatic drive to operate it (TRUE) or no drive (FALSE)

SmokeStop IfcPropertySingleValue IfcBoolean

Indication whether the object is designed to provide a smoke stop (TRUE) or not (FALSE).

FireExit IfcPropertySingleValue IfcBoolean

Indication whether this object is designed to serve as an exit in the case of fire (TRUE) or not (FALSE).

Here it defines an exit window in accordance to the national building code.

WaterTightnessRating IfcPropertySingleValue IfcLabel

Water tightness rating for this object. It is provided according to the national building code.

MechanicalLoadRating IfcPropertySingleValue IfcLabel

Mechanical load rating for this object. It is provided according to the national building code.

WindLoadRating IfcPropertySingleValue IfcLabel

Wind load resistance rating for this object. It is provided according to the national building code.
