HVAC Equipment

In this section all HVAC Equipment realted information needed to satisfy the Exchange HVAC Model (Space) will be described.

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
Owner History The Owner history of the HVAC Equipment must be asserted				HVAC Designer	Owner History (FP)
Placement and shape The shape representation and placement for the HVAC equipment should be asserted. The shape representation of an item of HVAC equipment is typically a representation map which is defined for the equipment type and then referenced for each occurrence. Each occurrence specifies its own placement. Within the representation map, the particular form of the shape representation may differ according to the life cycle stage as with flow segments. Generally, the representations selected for the flow fitting representation map will follow the representations selected for flow segments being either: Axis Representation Body Representation Swept solid CSG Bounding box Boundary representation (Brep) Note that since IFC generally allows for elements to have multiple shape representations, provision of shape representations of electrical systems at different lifecycle stages should be considered as cumulative and not as alternative. Components that may be located in technical spaces and that may impact on space provision are suggested in the list below				HVAC Designer Product Manufacturer Product Supplier	Model Ventilation Equipment (FP)
