5.4.4.8 Pset_BuildingStoreyCommon

5.4.4.8.1 Semantic definition

Properties common to the definition of all instances of IfcBuildingStorey. Please note that several building attributes are handled directly at the IfcBuildingStorey instance, the building storey number (or short name) by IfcBuildingStorey.Name, the building storey name (or long name) by IfcBuildingStorey.LongName, and the description (or comments) by IfcBuildingStorey.Description. Actual building storey quantities, like building storey perimeter, building storey area and building storey volume are provided by IfcElementQuantity, and the building storey classification according to national building code by IfcClassificationReference.

5.4.4.8.2 Applicable entities

5.4.4.8.3 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.

EntranceLevel IfcPropertySingleValue IfcBoolean

Indication whether this building storey is an entrance level to the building (TRUE), or (FALSE) if otherwise.

AboveGround IfcPropertySingleValue IfcLogical

Indication whether this building storey is fully above ground (TRUE), or below ground (FALSE), or partially above and below ground (UNKNOWN) - as in sloped terrain.

SprinklerProtection IfcPropertySingleValue IfcBoolean

Indication whether this object is sprinkler protected (TRUE) or not (FALSE).

SprinklerProtectionAutomatic IfcPropertySingleValue IfcBoolean

Indication whether this object has an automatic sprinkler protection (TRUE) or not (FALSE). It should only be given, if the property "SprinklerProtection" is set to TRUE.

LoadBearingCapacity IfcPropertySingleValue IfcPlanarForceMeasure

Maximum load bearing capacity of the floor structure throughtout the storey as designed.

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.

ElevationOfSSLRelative IfcPropertySingleValue IfcLengthMeasure

Elevation of the top surface of the structural slab level given in elevation above the local zero height. If the level varies and there is no significantly more prominent elevation, then this property may be omitted. In case of any inconsistency with the geometric positioning of the top surface, the geometric representation takes precedence.

ElevationOfFFLRelative IfcPropertySingleValue IfcLengthMeasure

Elevation of the top surface of the finished floor level given in elevation above the local zero height. If the level varies and there is no significantly more prominent elevation, then this property may be omitted. In case of any inconsistency with the geometric positioning of the top surface, the geometric representation takes precedence.
