Our facility is a 3-story suburban office building with one owner, and a large surface parking lot. All of the lighting in the parking lot is owned and maintained by the utility company, and we pay a monthly rental fee for the lighting. Do we need to include the usage of this lighting energy in our Energy Star calculations? (It's the same amount each month on our statement since we rent it for a flat rate, so no way to show savings due to photocells, timing adjustments, upgraded fixtures, etc.). The lighting is separately metered and on a different bill than the main building energy bill.
