Per 10 CFR 440.21(i) and WPN 19-4: Revised Energy Audit Approval Procedures, Related Audit and Materials Approval, Weatherization Grantees are required to submit their energy audits and priority lists for approval every 5-years. The Grantee is required to submit their energy audit no less than 6 months prior to the expiration date of their current audit approval. DOE encourages Grantees coordinate with their assigned DOE Project Officer a minimum of one year before the expiration of the five year audit cycle to:
- Review WPN 19-4 and attachments and prepare the materials for submission.
- Inform your Project Officer whether there will be a new energy audit tool(s) or if a revised/updated version of the current approved energy audit tool will be submitted.
- Grantees requesting approval to use the currently DOE-approved energy audits (listed below) are not required to describe the energy estimating methodology, but are still required to demonstrate competence with their selected audit and are required to provide the related supporting documentation called out in WPN 19-4.
