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 their fuel costs while contributing to national energy conservation through increased energy efficiency and client education. Households that include young children, elderly or disabled members are given priority for service. 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 under Title IV of the Energy Conservation and Production Act and amended by the National Energy Conservation Policy Act, the Energy Security Act, the Human Services Reauthorization Act of 1984, and the State Energy Efficiency Programs Improvement Act of 1990. The program is administered and funded at the federal level by the U.S. Department of Energy (DOE).
