2023 Multifamily Energy & Water Survey
Thank you for helping the industry refresh the energy and water scores for multifamily buildings. Stay tuned for more information on the results coming in 2024.
About the Survey
Fannie Mae partnered with industry leaders on a national survey effort to collect multifamily property energy and water consumption and costs in the United States. Industry partners who participated included Commercial Real Estate Finance Council (CREFC), Enterprise Community Partners, Mortgage Bankers Association (MBA), National Apartment Association (NAA), National Council of State Housing Agencies (NCSHA), National Multifamily Housing Council (NMHC), NeighborWorks America, Stewards of Affordable Housing for the Future (SAHF), and Urban Land Institute (ULI). Bright Power, a firm with expertise in multifamily energy and water efficiency, assisted Fannie Mae in the collection and analysis of the data. The anonymized survey data will be used to update the ENERGY STAR® 1-100 energy performance score and the U.S. Environment Protection Agency’s (EPA) Water Score for multifamily housing. These publicly available metrics allow building owners and managers to track and compare their energy and water use.
Unlike commercial buildings, multifamily properties do not have a federally supported national survey of utility consumption, cost, and building characteristics. To fill this data gap, Fannie Mae assembled a team and launched a survey for multifamily properties in 2012. This effort resulted in the development of the 1 – 100 ENERGY STAR Score for Multifamily Housing released in 2014 and the EPA’s Water Score for Multifamily Housing released in 2017. After a decade, it is time to update the data underlying the scores to better represent the current energy and water use landscape..
The 2023 Survey was open from March 1, 2023 through August 31, 2023.

All survey responses will be held in strict confidentiality. Identifying information will be removed from the data and no property, financial, owner, or resident information will be included in the published survey data or the data provided to EPA. No building-identifying information will be made available for any commercial or business intelligence purposes; an anonymized building data set will be shared with U.S. EPA solely for purposes related to the Multifamily Energy and Water Survey. This anonymized data set will later be shared on Fannie Mae’s website for public use in conjunction with the updated ENERGY STAR Score for Multifamily Housing launch, anticipated in Q4 2024.
Contact information will only be used if the survey administrator, Bright Power, needs to contact survey respondents with follow-up questions to ensure a complete response.
We are thankful for the collaborative partnership from the following organizations as well as the numerous individuals and organizations from the multifamily industry who provided feedback on the survey prior to launch.
