Class properties
Property set: Attributes

Optional description, provided for exchanging informative comments.

The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute 'PredefinedType' is set to USERDEFINED.

Assignment of a globally unique identifier within the entire software world.

Long name for the context as used for reference purposes.

Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule.

The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute PredefinedType is set to USERDEFINED or when the concrete entity instantiated does not have a PredefinedType attribute. The latter is the case in some exceptional leaf classes and when instantiating IfcBuiltElement directly.

Property set: Pset_AirSideSystemInformation

The air flowrate required to satisfy the sensible peak loads.

This enumeration defines the basic types of air side systems (e.g., SingleDuct, DualDuct, Multizone, etc.).

This enumeration specifies the basic types of possible air side systems (e.g., Constant Volume, Variable Volume, etc.).

Diversity of appliance load.
