The RBSA is designed to develop a characterization of the residential sector that considers the diverse climates, building practices and fuel choices across the region. This study informs future energy planning efforts as well as energy efficiency utility programs and rebates offered by the region's utilities, the Energy Trust of Oregon and the Bonneville Power Administration. The most recent RSBA was fielded in 2016. Those reports, database, and supporting documentation are included in the corresponding drop downs below.
On July 15, 2021, staff from the Northwest Energy Efficiency Alliance (NEEA) presented a second webinar with details about the upcoming Residential Building Stock Assessment (RBSA 2022). Webinar #2 topics included the priorities, scope, timeline, design, and anticipated regional coordination of the RBSA 2022 study. Watch the recorded webinar below, or view the presentation slide deck here.

RBSA II - Update Memo:
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 - see this technical memo for more info.
2011-2012 RBSA Supporting Documentation
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.
