Demographics: Energy Sources for Heating Equipment Used for Space Heating

In the United States in 2003, non-mall buildings accounted for 64,783 million square feet of total floor space of which 60,028 million square feet, or 93%, had sources of space heating. Natural gas contributed to space heating for about 62% of this area. (About 10% of this floor space was actually not heated.) Mall buildings add an estimated 213 thousand buildings comprising 6.9 billion square feet. (In the last EIA CBECS, malls represented 6.6 percent of total energy consumption for commercial building space heating.)
