Energy consumption and efficiency analysis activities are part of a separate office, under the assistant administrator for energy analysis.
Although the EIA organizational structure has undergone several changes since the establishment of the agency, the primary mission of the unit responsible for the consumption surveys has always been to collect and disseminate information about the demand and consumption of energy (French, 2007). The energy consumption and efficiency statistics unit organizes its work around energy-use sectors, including commercial, residential, and manufacturing, as described below:
Commercial: The Commercial Buildings Energy Consumption Survey (CBECS) covers energy consumption in the commercial sector. For its consumption surveys, EIA defines a building as a structure that is completely enclosed, with walls that extend from the foundation to the roof, and a commercial building as a building intended for human occupancy, in which at least half of the floor space is used for a purpose that is not residential, industrial, or agricultural. Based on the definition used by EIA, institutional and organizational buildings such as schools, libraries, correctional institutions, and houses of worship are included in the CBECS. On the other hand, unenclosed energy-consuming structures, such as street lights, pumping stations, and billboards, are not included. Some enclosed structures not intended for human occupancy are also excluded, such as cooling towers and monuments.
Residential: The Residential Energy Consumption Survey (RECS) covers energy consumption in occupied, primary housing units. Vacant and seasonal housing is not included, nor are group quarters, such as prisons, nursing homes, and college dormitories.
Manufacturing: The Manufacturing Energy Consumption Survey (MECS) accounts for energy consumption by manufacturing establishments with five or more employees. Energy consumption by non-manufacturing industrial sectors such as agriculture, mining, and construction is not captured by the MECS.
From 1983 to 1994 EIA’s Residential Transportation Energy Consumption Survey (RTECS) collected data on energy consumption by household highway vehicles, which account for nearly a third of domestic energy consumption, but a lack of funding caused this survey to be discontinued
