2022 RBSA Data Reveals Northwest Energy Trends for LEDs, Smart Thermostats and more

The results of the 2022 Residential Building Stock Assessment (RBSA) are now available. The RBSA collects data on more than 100 building characteristics and supports the region with an up-to-date and representative characterization of existing Northwest residential building stock and energy trends. This fundamental primary research is used by NEEA, Northwest utilities, and other regional stakeholders to improve and expand the region’s understanding of residential energy usage and support regional efficiency programs and energy planning. The 2022 RBSA gathered energy usage and building characteristic data from more than 2,000 single-family and multifamily residences in Idaho, Montana, Oregon, and Washington.
