ENERGY STAR certification for Multifamily Housing is available to properties with:
- 2 or more units per building
- 20 or more units per campus
- Minimum 80% occupancy rate
- ENERGY STAR score of 75 or more
Other notes about requirements:
- There is no minimum square footage
- Your occupancy rate must be at least 80% to be eligible for ENERGY STAR certification, but you can still get a score if your occupancy rate is lower
- Your occupancy rate does not affect your score
- If you have less than 20 units, you can't get a score; you will get an EUI instead.
- Communities of detached single-family homes are not eligible. If your property is a mix of multifamily and single-family homes, the property would still be eligible as long as the single-family homes are less than 25% of the total GFA.
- In general, multiple multifamily housing buildings on a campus MUST be certified as a single property. There is one exception:
- If the buildings are being built over a number of years, and phase 1 of the project will be complete and occupied before the other phases are complete. In this scenario, if Phase I has twelve months of usage data, it is eligible to apply for certification for Phase 1. When each additional phase is complete, the GFA of the property will be increased to account for the additional buildings (like a property addition) as described in this FAQ.
