Methodology & Research

Overview of the 2018 CBECS process

The Commercial Buildings Energy Consumption Survey (CBECS) is conducted periodically by the U.S. Energy Information Administration (EIA) to provide basic statistical information about energy consumption, expenditures, and the energy-related characteristics of U.S. commercial buildings. The CBECS is conducted in two phases, the Buildings Survey and the Energy Supplier Survey. For details about how we gathered this information for the 2018 CBECS from start to finish, select a step in the diagram above or a link in the next paragraph.

First, we constructed a frame and selected a sample. Interviewers visited the sampled buildings to conduct the Buildings Survey in person or to encourage respondents to respond online. In addition to information about the building and its equipment, we asked respondents for the names of their energy suppliers and account numbers so that we could reach out to these suppliers to conduct the Energy Supplier Survey. As we collected data from both surveys, we processed the data using editing and imputation. We modeled energy end-use consumption, and we published the resulting data.
