Create a list of exterior subface (apertures + doors) constructions that can be used to edit or create a ConstructionSet object.

## Inputs

* **window**

  A construction object for apertures with an Outdoors boundary condition and a Wall face type for their parent face. This can also be text for the identifier of the construction within the library. 
* **skylight**

  A construction object for apertures with an Outdoors boundary condition and a RoofCeiling or Floor face type for their parent face. This can also be text for the identifier of the construction within the library. 
* **operable**

  A construction object for apertures with an Outdoors boundary condition and True is\_operable property. This can also be text for the identifier of the construction within the library. 
* **exterior\_door**

  A construction object for opaque doors with an Outdoors boundary condition and a Wall face type for their parent face. This can also be text for the identifier of the construction within the library. 
* **overhead\_door**

  A construction object for opaque doors with an Outdoors boundary condition and a RoofCeiling or Floor face type for their parent face. This can also be text for the identifier of the construction within the library. 
* **glass\_door**

  A construction object for all glass doors with an Outdoors boundary condition. This can also be text for the identifier of the construction within the library. 

## Outputs

* **subface\_set**

  A list of exterior subface constructions that can be used to edit or create a ConstructionSet object.
