1These climate regions were created by the Building America program, sponsored by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE).
2In earlier CBECS publications, BAS was referred to as Energy Management and Control System (EMCS).
3In versions of this table prior to January 2017, the row category labels for Separate computer areas and HVAC conservation features were reversed, i.e., the data in the Separate computer areas row category were actually for HVAC conservation features and vice versa.
Q = Data withheld either because the Relative Standard Error (RSE) was greater than 50 percent or fewer than 20 buildings were sampled.
N = No cases in reporting sample.
Notes:  ● Because of rounding, data may not sum to totals.  ● See Guide to the 2012 CBECS Detailed Tables or CBECS Terminology for definition of terms used in these tables and/or comparison of differences with prior CBECS tables.
