Attribute type: energy:delimitsBy

back

Definition

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"
