Data source: U.S. Energy Information Administration, Form EIA-871A of the 2018 Commercial Buildings Energy Consumption Survey
Notes: Because of rounding, data may not sum to totals. The Guide to the 2018 CBECS Tables and CBECS Terminology contain definitions of terms used in these tables and comparisons between previous CBECS tables. You can access both references from http://www.eia.gov/consumption/commercial/data/2018/.
Data are sample survey estimates with RSEs published in a tab on the Excel worksheet for this table.
aClimate zones are based on ASHRAE Standard 169-2021; see https://www.eia.gov/consumption/commercial/maps.php#defined.
Q = Data withheld either because the relative standard error (RSE) was greater than 50% or fewer than 20 buildings in reporting sample.
N = No buildings in reporting sample.
