EPA Releases First Multifamily ENERGY STAR® Scores


WASHINGTON, D.C. - The U.S. Environmental Protection Agency (EPA) has officially begun providing “1–100 ENERGY STAR®” scores for multifamily industry use, enabling owners to benchmark and track water and energy use to more effectively improve energy efficiency to their properties.

While the 1-100 score has long been available for commercial properties, recent metric updates now recognize the unique characteristics of multifamily housing. The multifamily score was derived from an EPA and Fannie Mae partnership where Fannie surveyed more than 1,000 multifamily properties nationwide. The data provided in that survey served as the basis for the markers developed for the final scoring system.

To calculate scores, building owners must input the necessary data into the ENERGY STAR Portfolio Manager® tool, which is available online at no cost. Data is kept private and shared only with the owner’s authorization. In cities that have mandated energy benchmarking, owners can share their data directly with the relevant local government officials.

To receive an accurate score, the EPA requires:

  • 12 months of complete energy data (includes common areas and individual units)
  • Gross floor area for all buildings
  • Total number of units in a low-rise, mid-rise and high-rise setting
  • Total number of bedrooms

Properties that receive a score of 75 or higher are eligible for program awards, including ENERGY STAR Certification. Portfolio Manager requires whole-building data, which includes utility bill information for individual units. If an owner is unable to obtain this data through an arrangement with the local utility company, the owner will be unable to calculate a building score. EPA made the 1-100 score for multifamily available on Sept. 16.
