Sub-surfaces are exceptions to the main surface construction. Examples include cold-bridging elements such as window lintels and opaque panels in a lightweight facade. You can define different sub-surface construction types for external walls, internal partitions and pitched roofs.
Sub-surfaces are modelled in the same detail as standard surfaces including the effect of thermal mass but not including any 2-D or 3-D heat conduction effects due to the interface between the sub-surface and the background parent surface.
To add a sub-surface, go to the surface you wish to work on, click on the Layout tab and select the Draw sub-surface command.
You can also define default constructions for doors.
Any opaque sub-surfaces created in a wall will have this construction.
Any opaque sub-surfaces created in any inside surface (partitons, internal floor etc) will have this construction.
Any opaque sub-surfaces created in any pitched roof will have this construction.
Defines the construction of external doors.
Defines the construction of internal doors.
