NEEA Releases Foundational Data on Northwest Residential Building Stock and Energy Usage, Supporting Regional Decision-Making
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.

RBSA metering data is comprised of end-use loads measured at 15-minute intervals over 27 consecutive months. The participants are a subset of the full RBSA Single-family Report. The “RBSA End Use Load Shape Data” file and the “RBSA End Use Load Shape Flags Data” file are two supplemental files for the main dataset. The Flag file provides a set of flags as to what homes were included in the main report. RBSA Metering and Load Shape Flags Information and the RBSA Data Dictionary are included to further explain the data.

[Updated April 2019] Issues with water flow measurement and envelope U-value calculations have been resolved and updated in both the reports and database. Additionally, an alternate weighting scheme has been developed which should provide better weighting at the sub-regional level.
