Residential Building Stock Assessment
The RBSA provides information on the energy use and characteristics of residential buildings and their installed equipment in the Northwest.
Comprehensive Data Collection on Northwest Residential Building Stock and Energy Trends
The Residential Building Stock Assessment (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.
2022 RBSA Data Reveals Northwest Energy Trends
The results of the 2022 RBSA are now available, featuring energy usage and building characteristic data collected from over 2,000 single-family and multifamily residences in Idaho, Montana, Oregon, and Washington. The data highlights trends in the adoption of technologies like LEDs and smart thermostats and supports informed decision-making for energy efficiency program opportunities.
