An occupant is a type of actor that defines the form of occupancy of a property.
The principal purpose of IfcOccupant is to determine the nature of occupancy of a property for a particular actor. All characteristics relating to the actor (name and organization details) are inherited from the IfcActor entity.
HISTORY New entity in IFC2x
Common Use Definitions
The following concepts are inherited at supertypes:
The Actor Assignment concept applies to this entity as shown in Table 240.
|IfcSpatialStructureElement||Indicates the property to be occupied. Particular details of the agreement relating to the occupancy of a property are dealt within the Pset_PropertyAgreement that is defined for the instance of IfcSpatialStructureElement. This means that an occupant may be related to a site, building, building storey or space through the IfcSpatialStructureElement.ElementComposition attribute. For instance, if the property concerned is several office spaces on a building storey, it might be appropriate to reference IfcBuildingStorey.ElementComposition=PARTIAL. Occupants of a property may be considered to be the parties to an agreement. The roles that the occupant may play in respect to an agreement are defined in the IfcOccupantTypeEnum enumeration. If the role is not specified by the predefined contents of this enumeration, the value USERDEFINED may be set and the ObjectType attribute asserted.|
|IfcControl||Indicates project directives issued by the actor.|
|IfcGroup||Indicates groups for which the actor is responsible.|
|IfcProduct||Indicates products for which the actor is responsible.|
|IfcProcess||Indicates processes for which the actor is responsible.|
|IfcResource||Indicates resources for which the actor is responsible.|
