The U.S. Department of Energy’s (DOE) Weatherization Assistance Program (WAP) requires all Grantees to utilize computerized energy audits specific for single-family, manufactured (mobile home), and multifamily dwellings to determine the most cost-effective energy conservation measures (ECM) to install.

• Per 10 CFR 440.21(i) and WPN 19-4: Revised Energy Audit Approval Procedures, Related Audit and Materials Approval, WAP Grantees are required to obtain approval or re-approval for their energy audit tools and/or priority lists every five years.      
• WAP Grantees are also required to submit their energy audit tool and/or priority lists to DOE no less than six months prior to the expiration date of their current approvals.

DOE encourages WAP Grantees to coordinate with their assigned WAP Technical and Programmatic Project Officers one year before their energy audit expiration date to:

• Review WPN 19-4 and attachments, and prepare the audit and supporting materials for submission. 
• Inform the Project Officers whether there will be a new energy audit tool for a building type (single family, manufactured, or multifamily) or if a revised/updated version of the current approved energy audit tool will be submitted. 

For energy audit procedure reviews, DOE reviews not only how the energy audit tool is used to estimate energy use and potential weatherization savings, but also how a Grantee implements its energy audit procedures. Therefore, Grantees requesting approval of any energy audit tool must provide a list of measures typically enabled and provide the input data, assumptions, and audit results (recommended measures) for at least 10 dwelling units of each housing type, e.g., 10 site-built audits, 10 manufactured home audits. If a Grantee requests multifamily approval and wishes to submit fewer than 10 multifamily audits, then the Grantee should contact the DOE Project Officers of record to discuss this requirement.
