Weatherization Assistance Program
General Information
- The Department of Energy’s (DOE) Weatherization Assistance Program (WAP) has since 1976 provided weatherization services to more than 5.6 million low-income families. Through WAP, weatherization service providers install energy efficiency measures in the homes of qualifying homeowners free of charge. DOE works directly with the states which in turn contract with local governments or nonprofit agencies, such as community action agencies, to deliver weatherization services to low-income clients in their areas.
- Information and resources related to WAP are available at the Weatherization Assistance Program Technical Assistance Center (WAPTAC) website and on DOE’s website.
Statute and Regulations
- The new EPA Lead Safe work regulations, effective April 22, 2010, enables more flexibility for Weatherizers regarding implementation. Although flexibility has been granted, a recent NCAF survey of over 400 WAP agencies shows that additional flexibility in implementation is still needed. View the complete survey on the NCAF website. You can also read the complete NCAF EPA update highlighting continued concerns and confusion regarding the regulations.*
- DOE issued new WAP regulations that enable buildings containing rental units identified by HUD and USDA in DOE's March 2, 2010 guidance to more easily meet the eligibility requirements for weatherization assistance.
- Authorizing legislation for WAP codified at 42 U.S.C. Sections 6861 – 6873.
- Regulations for WAP codified at 10 C.F.R. part 400 and 10 C.F.R. part 600, and are available here. American Recovery and Reinvestment Act of 2009 (ARRA) amendments to the regulations are available here.
