Weatherization Assistance Program

    About the Weatherization Assistance Program

    THDA serves as the grantee agency for Tennessee's weatherization program. A network of local community agencies and governments provide weatherization services in Tennessee's 95 counties, based on availability of funding.

    The Weatherization Assistance Program is designed to assist low-income households in reducing heating and cooling costs for low-income families, particularly for the elderly, people with disabilities, and children, by improving the energy efficiency of their homes while ensuring their health and safety.

    Weatherization helps reduce energy costs by increasing a dwelling's energy efficiency. Examples of common weatherization measures include air sealing, duct sealing, and adding insulation to attics, walls and floors. Site specific weatherization measures are determined after a detailed energy audit is conducted by a certified energy auditor.

    The Weatherization Assistance Program was established by Congress in 1976 to alleviate the disproportionate energy burden of low-income households. The U.S. Department of Energy’s (DOE) Efficiency and Renewables Office has managed the program since 1993. WAP is the nation’s oldest whole-house energy efficiency program, with a unique mandate to reduce energy costs for low-income households.
