California Commercial End-Use Survey (CEUS) 2018-2021

The California Commercial End-Use Survey (CEUS, pronounced "soos" like Dr. Seuss) is a comprehensive study of commercial sector energy use. The CEUS is the primary form of collecting commercial sector energy consumption and end-use profiles to support the California Energy Commission’s (Energy Commission) commercial sector forecast model. On-site surveys of commercial buildings are conducted to gather detailed information about building characteristics, business type, and equipment.

The project is managed by the Energy Commission in cooperation with all major investor-owned utilities including Southern California Edison (SCE), Pacific Gas and Electric (PG&E), Southern California Gas (SoCalGas), and San Diego Gas and Electric (SDG&E), as well as major publicly-owned utilities including the Los Angeles Department of Water and Power (LADWP) and the Sacramento Municipal Utility District (SMUD). The project is expected to be completed by March of 2021.

Project Goals & Objectives

  • Accurately characterize building economic activity and assess NAICS (North American Industry Classification System) code misclassification in utility billing system data.
  • Calculate end-use fuel saturations at the forecasting zone level by building type.
  • Calculate robust commercial floor space estimates at the forecasting zone level by building type.
  • Calculate annual whole-building energy use estimates at the forecasting zone level by building type.
  • Calculate annual whole-building hourly load profiles at the forecasting zone level by building type.
  • Incorporate advanced metering infrastructure (AMI) electricity consumption data into forecasting model input development.
  • Evaluate the potential for over-sampling new construction to allow calculation of statistically significant population estimates of the most recent building stock vintage.
  • Examine the potential for purchasing commercial real estate data for use in forecasting and demand analysis.

Project Design and Methodology

The proposed design is very unconventional compared to what has been done in the past in California. The primary design focus is to collect limited information on a few key variables from as many sites as possible to achieve better statistical precision of population estimates. The proposed approach is to collect on-site data for a sample of 27,000 commercial buildings.

The primary means of data collection is through on-site visits of commercial businesses selected to participate in the project. The participants are selected randomly by utility service area, climate region, building type, and energy consumption level.

ADM Associates, Inc. has been hired by the Energy Commission to conduct on-site data collection.
