energy:ThermalZone

Type

Feature Type

Definition

A thermal zone is a zone of a building which serves as unit for the building heating and cooling simulation. For the simulation, a thermal zone is considered as isothermal. It is a semantic object, which may be or not related to a geometric entity.

Attribute type: energy:contains

back

Definition

Relation of a thermal zone with one or several usage zones. If a thermal zone is related to more than one usage zone, the UsageZone attribute floorArea is mandatory in order to enable the calculation of average heating / cooling schedules. A UsageZone object can only be referenced by one ThermalZone object.
