Feature Type
Thermal Boundaries delimit Thermal Zones. Thermal Boundaries represent physical relationships between two Thermal Zones or a Thermal Zone and the building environment.

ThermalComponent
Attribute type: energy:delimitsBy |
In case two ThermalZones are referenced via the relation "delimitsBy", the following rule concerning the order of the related
objects applys:
- For ThermalBoundary objects of type "intermediaryFloor!, the first related object is the upper
ThermalZone, and the seconr related object is the lower ThermalZone
- For all other ThermalBoundary types, the first
related ThermalZone is in contact with the last Layer of the corresponding AbstractConstruction, and the second related ThermalZone
is in contact with the first Layer of the corresponding AbstractConstruction,
Last layer is facing the first ThermalZone
and First layer is facing the second ThermalZone of the relation "delimitsBy"
