Table B36. Percent of Floorspace Lit When Open, Number of Buildings and Floorspace for

Number of Buildings (thousand) Total Floorspace (million square feet)

See "Guide to the Tables" or "Glossary" for further explanations of the terms used in this table. 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

 "Not Lit" includes buildings that were zero percent lit when open, buildings that were never open, and buildings that did not use any electricity. b The definition for one or more of these row items has changed and may not be directly comparable with past CBECS estimates. See "Guide to 

the Tables" for discussion of the differences.

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.

Notes: ● HVAC = Heating, Ventilation, and Air Conditioning. ● Due to rounding, data may not sum to totals.
