Survey Characteristics



The survey was conducted by computer-assisted telephone interview, using the same buildings selected in 1995. A sample of new construction of buildings over 10,000 square feet was added (and data for smaller new buildings were imputed). Starting this year, energy consumption and expenditures data were collected from the building respondents, and energy suppliers were contacted only if the data provided by the building respondent were inadequate. The smallest level of geographic detail for which data were available was the census division.



The sampling frame was redesigned and a new area frame listing was created for the first time since 1986. The area frame was supplemented with lists of large and special buildings. New data collection procedures were implemented for shopping malls, universities, and hospitals. The smallest level of geographic detail for which data were available was the census division.


The area frame was updated based on a commercial version of the USPS delivery sequence file. No data were released.


Data collection currently suspended (as of December 2011).

stages: a building characteristics survey and an energy suppliers survey. During the first stage of the data collection, interviewers visit the buildings selected into the sample and ask a representative, such as the building’s owner, manager, or other knowledgeable person, to complete the survey. During the second stage of the data collection, the energy suppliers (e.g. utilities) of the buildings for which inadequate information was provided in the first stage are contacted to obtain usage and expenditure data for those buildings from the supplier’s records. This usually happens if the building respondent is not able to report energy usage and cost information or if the information provided falls outside the range of “likely” energy consumption, determined based on regression models that take into account responses from previous years. In a typical CBECS, the energy suppliers for about half of the buildings in the sample need to be contacted (Michaels, 2010). Unlike the building survey responses, the suppliers’ responses are mandatory under the Federal Energy Administration Act. Box 3-1 shows the topics included
