IfcCompartment

Definition from IAI: The Compartment entity (IfcCompartment) is considered as a grouping of Spaces (IfcSpace) for compartmentation purposes. It is an aggregate of spaces under this view, using the IfcRelAssignsToGroup objectified relationship.

On of the purposes to define a compartment is the fire compartment. In this case it defines the geometric information about the fire compartment (through the contained spaces) and information, whether this compartment is ventilated or sprinkler protected. The fire risk factors are normally defined within a classification system and they are assigned by using the IfcRelAssociatesClassification relationship.
