2022 California Commercial End-Use Survey (CEUS): Final Report

The 2022 California Commercial End-Use Survey (CEUS) was a comprehensive study of commercial sector energy use, primarily designed to support the state’s energy demand forecasting activities. ADM Associates, Inc. (ADM) performed the survey under contract to the California Energy Commission. The survey focuses on selective building systems data, electricity and gas usage, equipment inventories, occupancy schedules and primary business activities, and other commercial building characteristics.

A stratified random sample of nearly 27,000 commercial facilities was targeted from the service areas of Pacific Gas & Electric Company (PG&E), San Diego Gas and Electric (SDG&E), Southern California Edison (SCE), Southern California Gas Company (SoCalGas), Los Angeles Department of Water and Power (LADWP), and the Sacramento Municipal Utility District (SMUD). The primary sampling unit was the survey-site, defined as a single commercial entity operating in a contiguous commercial space (i.e., all or part of one or more commercial buildings that are not separated by other buildings, or by public roads). The sample was stratified by utility service area, Forecast Zone, Building-type, vintage (existing & new), and energy consumption level.

The 2022 CEUS was the first instance of the CEUS to use paperless survey forms. This survey used a web-based application (app) specifically designed for this CEUS survey to address the unique characteristics of this survey. The app is called the “CEUS Tool” and was a major part of this data collection effort.

For each utility service area, floor stocks, fuel shares, electric and natural gas consumption, energy use, and hourly whole building load profiles were estimated for the twelve commercial Building-type categories.
