Average Cost Per Dwelling Unit

This table provides Weatherization Assistance Program Grantees and Subgrantees current and historical average cost per dwelling units (ACPU) allowable expenditures.

The Average Cost Per Dwelling Unit (ACPU) of financial assistance provided under WAP for labor, weatherization materials, and related matters cannot exceed $6,500, as adjusted (see, 10 CFR §440.18(a) and (c)). The adjusted maximum annual ACPU for each Program Year (PY) is determined by using the percentage increase in the Consumer Price Index (CPI) (all items, United States city average) for the previous calendar year or 3%, whichever is less. The CPI percent or 3 percent is added to the previous PY ACPU to determine the ACPU for the next PY. Each year, DOE includes the recalculated ACPU in the Program Year Weatherization Grant Application, currently WPN 24-1.

In accordance with 10 CFR Part 440.18(b) and (c), the expenditure of financial assistance provided under WAP for labor, weatherization materials, and related matters for a renewable energy system, shall not exceed an average of $3,000 per dwelling unit, as adjusted.
 
Note: The adjusted average for renewable energy measures is not a separate average, but part of the overall adjusted average expenditure limit. Currently Appendix A allows for use of solar (thermal) water heating systems. Grantees must receive approval to install renewables from DOE through their 5-year DOE-approved energy audit process.
