National Retrospective Evaluation of the Weatherization Assistance Program (WAP)

DOE sponsored two major national evaluations of the Weatherization Assistance Program (WAP). The evaluations were performed to provide information on the costs and benefits of WAP services in different parts of the country and for different types of housing. They were also performed to provide a comprehensive picture of the Program, including the characteristics of the clients, housing stock, and service providers.

The two evaluations were multiyear, peer-reviewed, statistically robust efforts led by the Oak Ridge National Laboratory (ORNL). The Retrospective Evaluation covered Program Year (PY) 2008 and is reflective of a typical year in WAP operations. The Recovery Act Evaluation covered Program Year 2010 and provides insights into the unique Program that was administered by DOE in the national effort to create jobs and promote economic recovery as part of the American Recovery and Reinvestment Act of 2009 (ARRA).

Both evaluations are nearing completion. The Retrospective Evaluation was comprised of 20 individual studies, and the Recovery Act Evaluation was comprised of 14 individual studies. Final reports for these individual studies as well as summary reports for each evaluation have been written and are currently being reviewed by DOE. Access to these reports will be provided via this web site once the reports have been approved by DOE for release. In the interim, a Summary of Results has been prepared. The evaluations found that the Program provides cost-effective energy savings to American families, provides additional health and safety benefits, supports jobs, and provides a stable platform for additional investment in energy efficiency.
