Results for the 2022 Existing Single Family Building Upgrades Study are now available! You can currently explore the data in the Results section of the Cost-Effectiveness Explorer. This data is not available for use in policy creation yet, but will be available soon.
The report analyzes a wide range of efficiency measures for cost effectiveness, using a one-story, three-bedroom prototype with attached two-car garage. The analyses included measures such as adding insulation, replacing windows, and duct upgrades, fuel substitution measures that upgrade space heating and water heating to heat pumps, and solar photovoltaics (PV) for three vintages (pre-1978, 1978-1991, and 1992-2005) and all 16 climate zones.
Due to the extensive analyses and the large number of possible scenarios evaluated, a narrowed set of results were selected to display on the Explorer. However, the complete datasets containing all findings are available.
