You have two options to receive an ENERGY STAR score for a property with a parking:
- Sub-meter your parking and exclude its energy and Gross Floor Area (GFA). (*Recommended*)
- Do not enter a parking Property Use
- Do not enter the energy for your parking
- If your parking garage is physically connected with your building and part of a single structure, then the parking (Fully or Partially Enclosed) cannot be more than 75% of the total Property GFA. For example, a property that is 100,000 square foot, with 80,000 sq ft Parking and 20,000 sq ft Office is considered a Parking Garage by EPA and is not permitted to earn ENERGY STAR certification. This limit does not apply to Open Parking Lots.
- If your parking garage is not physically connected to your building, but rather is a separate structure then there is no limit as to its size.
- Benchmark your parking with your building and include its energy and GFA.
- Do not include Parking GFA in your Self-reported Property GFA
- Include your Parking GFA in a separate "Parking" Property Use
- Report the GFA of each type of parking (Fully Enclosed, Partially Enclosed, and Open)
- Include all parking energy in your energy meters.
- Regardless of physical connection, the GFA of your Parking (Fully Enclosed and Partially Enclosed) cannot account be more than 50% of your total Property GFA.
Why? The ENERGY STAR score provides an assessment of the building, not its parking area. If it is not possible to sub-meter your parking area, then Portfolio Manager will estimate the amount of energy parking uses and subtract that out before calculating your metrics.
