The Energy Index for Commercial Buildings

Welcome to the Energy Index for Commercial Buildings. Data for this tool comes from the Energy Information Administration’s (EIA) 2003 Commercial Buildings Energy Consumption Survey (CBECS). Select categories from the CBECS micro data allow users to search on common building characteristics that impact energy use. Users may select multiple criteria, however if the resulting sample size is too small, the data will be unreliable. If nothing is selected results yield national totals for commercial buildings. For more information on CBECS, visit EIA’s website.
