In general, users should not include their parking Gross Floor Area (GFA) in their property GFA. However, there is one exception: when the property is a Parking Garage (which we define as any property where the parking GFA is 75% or more of the total property GFA).
If you have a Parking Garage:
- Enter a single* Property Use (Parking) and separate out the open, partially enclosed, and completely enclosed parking.
- Enter your Property GFA as the sum of the partially enclosed and completely enclosed parking. That is considered the "building."
- If you have an open parking lot, we will estimate the energy used by the open parking and subtract that before calculating your metrics.
*If you have other property used in your parking garage that are less than 25% of the GFA and cannot get a score (say a small retail shop on the ground floor), you do not have to break it out into a separate property use. This is consistent with our rules for when to break out a separate property use, which states that you should only break out a separate Property Use if:
- It accounts for more than 25% of the property's GFA, OR
- It is a Property Use that can get an ENERGY STAR Score. Retail can only get a score if it is an individual store, greater than 5,000 sq ft, and has an exterior entrance. Ground-floor retail is not eligible for an ENERGY STAR Score.
