What data was used to develop the score for multifamily properties? Follow

For the ENERGY STAR score for multifamily properties, the reference data used to establish the peer building population in the United States is Fannie Mae’s Multifamily Energy and Water Market Research Survey.  This survey was part of Fannie Mae’s Multifamily Green Initiative to improve energy and water efficiency and enhance environmental and financial sustainability of multifamily housing properties.  The survey was conducted in 2012 and 2013, and collected whole building energy consumption data for the calendar year 2011.

The Multifamily Green Initiative is part of the Fannie Mae Multifamily Mortgage Business, which supports the U.S. multifamily housing market by providing a stable source of secondary mortgage financing for qualified, affordable housing. Fannie Mae finances multifamily rental apartments, cooperatives, military, seniors, students, and manufactured housing.  More information on Fannie Mae’s Green Initiative: www.FannieMaeGreenInitiative.com.

We anticipate the next update for the Multifamily model will be in about 5 years (in general, EPA strives to update each ENERGY STAR score at least once every 5 years). More
