 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) .

 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.
