IfcBuildingStorey
What is IfcBuildingStorey?
IfcBuildingStorey represents a single floor level within a building. It defines the vertical organisation of a building and contains all elements located on that storey. The elevation property defines the height of the storey relative to the building reference point.

Real-World Usage
Storeys are the primary way construction teams navigate BIM models. Filtering elements by storey is essential for floor-by-floor progress tracking, material takeoffs, and coordinating work between trades on the same level.

IfcBuilding
IfcBuilding represents a structure that provides shelter for its occupants or contents. It is the primary spatial container in the IFC hierarchy, grouping building storeys and their contained elements. A single IfcSite can contain multiple IfcBuilding instances for campus or complex projects.
Spatial ElementIfcSpace
IfcSpace represents a defined area or volume within a building, typically corresponding to a room or functional zone. Spaces carry data about their intended use, floor area, volume, and environmental requirements. They are bounded by building elements like walls, slabs, and doors.
Building ElementIfcWall
IfcWall represents a vertical construction element that bounds or subdivides spaces. Walls are one of the most fundamental building elements in any IFC model, defining the physical envelope and internal partitioning of a building. IfcWall can represent both load-bearing structural walls and non-load-bearing partitions.
Building ElementIfcSlab
IfcSlab represents a horizontal construction element that forms the floor, roof, or landing of a building. Slabs can be classified as floor slabs, roof slabs, landing slabs, or base slabs (foundations). They are typically the largest elements by area in a building model.
