New Report Identifies Challenges and Opportunities to Achieving 50% Energy Savings in Homes

July 22, 2011

The U.S. Department of Energy’s Building America program works to conduct research to develop market-ready energy solutions that improve efficiency of new and existing homes in each U.S. climate zone, while increasing comfort, safety, and durability. Armed with 15 research teams, national laboratory support, and a just-released roadmap report, Building America aims to reduce home energy use by 30%-50% (compared to 2009 energy codes for new homes and pre-retrofit energy use for existing homes).  

Specifically, the report, Challenges and Opportunities to Achieve 50% Energy Savings in Homes: National Laboratory White Papers ((PDF 1.3 MB) Download Adobe Reader), presents key opportunities, gaps, and barriers that must be addressed to meet Building America’s long-term 50% energy savings goal. Developed by researchers from four national laboratories—Lawrence Berkeley National Laboratory, National Renewable Energy Laboratory, Oak Ridge National Laboratory, and Pacific Northwest National Laboratory—the report focuses primarily on retrofit of the more than 116 million existing homes in the United States.  

Currently, Building America's residential systems research tasks are designed to evaluate performance and achieve market acceptance of energy efficiency measures through a three-step approach:  individual measures; whole-house or systems evaluation; and, community-scale projects. The analyses compiled in this report will help to define direction for the research, partnership opportunities, and information dissemination necessary to help achieve Building America’s mission.
