DEPRECATED This definition may be imported, but shall not be exported by applications Semantic definition

The IfcRelServicesBuildings is an objectified relationship that defines the relationship between a system and the sites, buildings, storeys, spaces, or spatial zones, it serves. Examples of systems are:

  • building service systems (heating, cooling, waste water system) represented by instances of IfcDistributionSystem;
  • building systems (fenestration, shading) represented by instances of IfcBuildingSystem;
  • zones as collection of logically grouped spaces represented by instances of IfcZone
  • idealized structural analysis systems represented by instances of IfcStructuralAnalysisModel. Entity inheritance Attributes
