IFC (IFC4X3_ADD2) development


Semantic definition

The number of storeys within a building. Captured for those cases where the IfcBuildingStorey entity is not used. Note that if IfcBuildingStorey is asserted and the number of storeys in a building can be determined from it, then this approach should be used in preference to setting a property for the number of storeys.
