In 2012, Fannie Mae conducted the Multifamily Energy and Water Market Research Survey (the "Fannie Mae Energy and Water Survey"), a national effort to understand trends in energy and water consumption and costs at multifamily properties. More than 1,000 multifamily property owners and managers across the U.S. submitted responses describing their property's characteristics and providing energy and water consumption and costs from January 2011 through December 2011.
Fannie Mae shared the Survey data with the U.S. Environmental Protection Agency to explore the development of the 1-100 ENERGY STAR® score for multifamily properties. In 2014, the EPA successfully launched the Score for use by multifamily housing.
Additionally, Fannie Mae published findings on these trends in multifamily properties. See Transforming Multifamily Housing: Fannie Mae's Green Initiative And ENERGY STAR® for Multifamily.
Fannie Mae would like to thank the many multifamily owners, property managers and industry organizations who contributed information to the Survey database, making the ENERGY STAR® Score a reality including:
