IfcBuildingSystem Class

Syntax

C++

class IfcBuildingSystem : public IfcSystem;

Description

A building system is a group by which building elements are grouped according to a common function within the facility. The group IfcBuildingSystem defines the occurrence of a specialized system for use within the context of a building and finishing fabric. Important functionalities for the description of a building system are derived from supertypes:

From IfcSystem it inherits the ability to couple the building system via IfcRelServicesBuildings to one or more IfcSpatialElement subtypes as necessary.
From IfcGroup it inherits the inverse attribute IsGroupedBy, pointing to the relationship class IfcRelAssignsToGroup. This allows to group building elements (instances of IfcBuildingElement subtypes, IfcFurnishingElement subtype, IfcElementAssembly and IfcTransportElement).
From IfcObjectDefinition it inherits the inverse attribute IsDecomposedBy pointing to the relationship class IfcRelAggregates. It provides the hierarchy between the separate (partial) building systems.
