Commercial Building Stock Assessment
The Commercial Building Stock Assessment provides information on the energy use and characteristics of commercial buildings and their installed equipment in the Northwest.
Essential Data for Regional Planning
The Commercial Building Stock Assessment (CBSA) collects, analyzes, and publishes information on the energy use and characteristics of commercial buildings and their installed equipment in the Northwest. This information is used to advance strategies for a more efficient and resilient energy system in the Northwest by NEEA, its funders, and other regional stakeholders. It supports Market Transformation and energy efficiency programs, energy resource forecasting and planning, utility conservation potential assessments, and utility integrated resource plans.

2025 CBSA Key Findings
The CBSA shows how energy use, building technologies and equipment use is changing across commercial and multi-family buildings in Idaho, Montana, Oregon and Washington. The 2025 report includes new areas of focus related to emerging energy use drivers, including dedicated server space, on-site energy generation and the availability of charging for electric vehicles (EVs).
66% LEDs
LEDs account for 66% of lighting fixtures in Northwest commercial buildings, up from 37% in 2019.
37% Heat Pumps
Approximately 37% of Northwest commercial buildings use heat pumps, compared to 18% in 2019. Adoption highest in education facilities (66%) and multifamily (57%).
61% Manual Thermostats
Manual thermostats are still common and can be found in 61% of buildings, indicating building controls continue to offer opportunities for savings.
5% EV Chargers
As adoption of electronic vehicles continues to increase, availability of charging stations has grown, with 5% of buildings offering electric vehicle charging.
29% Server Rooms
Twenty-nine percent of buildings have a dedicated server space, with the highest concentrations in education (64%) and office buildings (50%).

Better building data strengthens regional energy planning
The 2025 CBSA introduced a building-level sampling approach designed to provide more accurate estimates of the Northwest commercial building stock. The resulting data can help utilities, policymakers, researchers and industry professionals understand energy-saving potential, forecast energy demand and plan for the region’s changing building needs.
