Program Evaluations

The U.S. Department of Energy (DOE) regularly conducts evaluations of the Weatherization Assistance Program in order to verify energy savings and maximize service to weatherization clients. These evaluations are conducted by DOE's Oak Ridge National Laboratory (ORNL).

The evaluations have been critical to establishing the efficacy of energy efficiency measures for establishing cost-benefit ratios for the program as a whole. In terms of energy savings, weatherization clients save $1.83 for every dollar of DOE investment. And the ratio of quantifiable benefits of the program to costs is 1.48.
