Feature Type
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 |
One thermal zone may include several usage zones. If a thermal zone is related to more than one usage zone, the UsageZone
attribute floorArea is mantatory in order to enable the calculation of avarage heating / cooling schedules.
A UsageZone
object can only be referenced by one ThermalZone object.
