Design of the National Impact Evaluation for the DOE Weatherization Assistance Program

The U.S. Department of Energy is undertaking a new national evaluation of its Weatherization Assistance Program. Following the evaluation plan developed by the Oak Ridge National Laboratory, four studies will be performed to evaluate the Program as it was implemented in PY 2006: an impact assessment, a process assessment, special technical studies, and a synthesis study. This paper describes how the evaluation’s research questions were identified and discusses the plans for implementing the impact assessment and special technical studies.
