Feature Type
Thermal Boundaries delimit Thermal Zones. Thermal Boundaries represent physical relationships between two Thermal Zones, or a Thermal Zone and the outside environment, or a Thermal Zone and the ground. Their non-opening construction must be homogeneous.

ThermalOpening
Attribute type: energy:delimits |
In case two ThermalZones are referenced via the relation "delimits", 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 second 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.
1..2
ThermalZone
Attribute type: energy:relatesTo |
Reference of a ThermalBoundary to the corresponding physical boundary surface of the building, e.g. a WallSurface.
