Both can be accessed from the CBECS web site - http://www.eia.doe.gov/emeu/cbecs.  * Figures in this table do not include enclosed malls and strip malls. Mall buildings add an estimated 213 thousand buildings comprising 6.9 billion square feet. a  "Other" includes wood, coal, solar, and all other energy sources. Q=Data withheld because the Relative Standard Error (RSE) was greater than 50 percent, or fewer than 20 buildings were sampled. N=No responding cases in sample.
