Metaevaluations of the Weatherization Assistance Program (WAP)

Four metaevaluations were performed by the Oak Ridge National Laboratory (ORNL) to update the findings from the 1989 National Weatherization Assistance Program (WAP) Evaluation performed by ORNL in the early 1990’s. These metaevaluations used data collected from other studies of weatherization efforts performed for various states following the 1989 National Evaluation. The metaevaluations focused primarily on energy savings in homes heated by natural gas because the large majority of state-level studies addressed that fuel. For reference, the 1989 National Evaluation measured an average savings of 13% in pre-weatherization natural gas consumption for all end-uses in homes heated by natural gas. A summary and links to the four metaevaluations are provided below:
