Demographics: Commercial Space Heating - Sources of Data

The demographic data presented here is sourced in part from the most recent Commercial Buildings Energy Consumption Survey (CBECS) conducted in 2003 and sponsored by the Energy Information Administration (EIA). The next CBECS will be conducted in 2007. As stated by EIA: The CBECS is a national sample survey that collects information on the stock of U.S. commercial buildings, their energy –related building characteristics, and their energy consumption and expenditures. In the CBECS, commercial refers to any building that is neither residential, manufacturing/industrial, nor agricultural. At least 50% of the floor space must be used for purposes other than these for the building to be considered “commercial”. Another primary source of data is the 2006 Energy Data Book as issued by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy.
