There are 26 million apartments in the U.S. that house nine million families below the poverty level, and four million elderly households. The percentage of multifamily (MF) homes in states with large urban centers is 26% or more of the residential housing stock. Nehemiah Stone, Home Energy
author and energy consultant at the Benningfield Group
, prepared the attached report, "U.S. Multifamily Energy Efficiency Potential by 2020", to help national and regional policymakers understand the energy efficiency potential in the country’s existing MF sector. Writing in the May/June 2010 issue of Home Energy
, Nehemiah states:
"When we talk about possible energy efficiency improvements in the residential sector, we seldom think of opportunities outside of single-family (SF) homes, and we almost never consider technologies that are appropriate only for MF homes. In fact, almost every study of the potential for energy efficiency in the existing residential sector either excludes MF buildings or includes them as a nonspecific part of the aggregate residential sector."
What unique characteristics have you found in MF buildings and which technologies have you used that are appropriate for MF homes?
