# Subface Subset ![](/files/-Ma9OWWWPRcR5Rfl0WQa) ![](/files/-Mihpdl4Y-3GP-Jqg_Gp) - [\[source code\]](https://github.com/ladybug-tools/honeybee-grasshopper-energy/blob/master/honeybee_grasshopper_energy/src//HB%20Subface%20Subset.py) 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.ladybug.tools/hb-energy-primer/components/0_basicproperties/subface_subset.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
