Exterior Equipment

While equipment that is outside of a building does not impact the thermal performance of the building, the accounting of all end-uses including those outside of the building is important for many compliance and incentive programs that require building energy modeling. See the ExteriorLightsAndEq.idf example file for these input objects.

  • Exterior:Lights - describes the external site lighting for the building grounds, entrances, and facades which are either controlled by a schedule or when the sun is set.
  • Exterior:FuelEquipment - describes other energy consumption on the site that is external to the building other than lighting.
  • Exterior:WaterEquipment - describes the flow rate of water use on the building site outside of the building.

The input objects described in this section are further explained in the InputOutputReference under the heading "Group-Exterior Energy Use Equipment."
