IFC (IFC4X3_ADD2) under development Pset_SpaceCommon Semantic definition

Properties common to the definition of all occurrences of IfcSpace. Please note that several space attributes are handled directly at the IfcSpace instance, the space number (or short name) by IfcSpace.Name, the space name (or long name) by IfcSpace.LongName, and the description (or comments) by IfcSpace.Description. Actual space quantities, like space perimeter, space area and space volume are provided by IfcElementQuantity, and space classification according to national building code by IfcClassificationReference. The level above zero (relative to the building) for the slab row construction is provided by the IfcBuildingStorey.Elevation, the level above zero (relative to the building) for the floor finish is provided by the IfcSpace.ElevationWithFlooring.

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.

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.

GrossPlannedArea IfcPropertySingleValue IfcAreaMeasure

Total planned gross area of the spatial structure element. Used for programming the spatial structure element.

NetPlannedArea IfcPropertySingleValue IfcAreaMeasure

Total planned net area of the object. Used for programming the object.

PubliclyAccessible IfcPropertySingleValue IfcBoolean

Indication whether this space (in case of e.g., a toilet) is designed to serve as a publicly accessible space, e.g., for a public toilet (TRUE) or not (FALSE).
