Residential Building Stock Assessment

Supported by the region’s electric utilities, NEEA is conducting a comprehensive research study of energy efficiency in Pacific Northwest residential buildings – officially called Residential Building Stock Assessment (RBSA). This study will inform future Pacific Northwest energy planning efforts. Study results will be used to identify energy efficiency utility programs and rebates offered by the region’s utilities, the Energy Trust of Oregon and the Bonneville Power Administration.

The Northwest has no precedent for a residential field study of the size and representative nature of the RBSA. The sample included public (eighty-nine), investor-owned (seven) and three gas-only utilities in Washington, Oregon, Idaho, and western Montana.

Field surveys were conducted on more than 1,850 sites across the Northwest, including more than 1,400 single-family homes. The RBSA was designed to develop a characterization of the residential sector that takes into account the diverse climates, building practices, and fuel choices across the region.

This report includes a single-family report, a manufactured homes report, and a multi-family report.
