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 the
Guide to the 2012 CBECS Detailed Tables or CBECS Terminology for definitions of terms used in these tables and/or comparison of differences with prior CBECS tables. Both references can be accessed from http://www.eia.gov/consumption/commercial/data/2012/ • Site electricity is the amount of electricity delivered to commercial builidngs. Primary electricity, which is not included in the Total of major fuelscategory, is site electricity plus the conversion losses in the generation, transmission, and distribution processes. • Statistics for the Energy end uses category represent total consumption in buildings that have the end use, not consumption specifically for that particular end use. • HVAC = Heating, ventilation, and air conditioning.
