Sub-Surface Constructions

Construction tab in model data under Construction header

 

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.

 

Note: because DesignBuilder Version 1 does not have model data associated with 'openings', it is not possible to have more than one type of sub-surface on any particular 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 constructions for doors.

Walls

Any opaque sub-surfaces created in a wall will have this construction.

Internal

Any opaque sub-surfaces created in any inside surface (partitons, internal floor etc) will have this construction.

Roof

Any opaque sub-surfaces created in any pitched roof will have this construction.

External door

Defines the construction of external doors.

Internal door

Defines the construction of internal doors.
