Equipment

In this section all Equipment related information needed to satisfy the Exchange HVAC Model - (Systems) will be described.

Owner History

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
The owner history of the equipment must be asserted.				HVAC Designer	Model Ventilation Equipment (FP)

General Attributes

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
General attributes of the equipment types and occurrences may be specified including:
name to extend identification of the type or occurrence.				HVAC Designer	Model Ventilation Equipment (FP)
description that can be used for any further qualifying information.				HVAC Designer Product Manufacturer Product Supplier	Model Ventilation Equipment (FP)

Placement and Shape

Note that since IFC generally allows for elements to have multiple shape representations, provision of shape representations of ductwork systems at different lifecycle stages should be considered as cumulative and not as alternative.

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
Where information about equipment shape is to be exchanged as part of the building model specification, the placement and shape representation should be asserted. The shape representation of an item of ventilation 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)				HVAC Designer Product Manufacturer Product Supplier	Model Ventilation Equipment (FP)

Properties

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
Specification of properties that may be assigned through property sets as defined in the functional part. For ventilation equipment, properties will generally be defined for the equipment type. Properties specified vary according to the equipment type. Refer to the functional part for further details. Note that particular equipment types and their properties are identified through the specification of parameters with the functional part as shown.
