Set the ceiling plenum and/or floor plenum depth of rooms for any Dragonfly object (Room2Ds, Stories, Buildings, Model).

A Dragonfly Model, Building, Story or Room2D to have plenum depths assigned to it.

* **floor\_plenum**

A number for the depth that floor plenums extend into rooms. Setting this to a positive value will result in a separate plenum room being split off of the Room2D volume during translation from Dragonfly to Honeybee.

### Outputs

* **report**

Reports, errors, warnings, etc.

* **df\_obj**

The input Dragonfly object with ceiling or floor plenum depths set.
