92 CBECS MICRODATA FILE SPECIFICATIONS _README.TXT The 18 Public Use Data files of the 1992 Commercial Buildings Energy Consumption Survey (CBECS) data were constructed in ASCII (i.e. CE92F01T.TXT) and dBASE (CE92F01D.DBF) format. These files contain the 1992 CBECS basic data including building characteristics, energy consumption and expenditures, and temperature data. All files contain 6,734 records which represent commercial buildings from the 50 States and the District of Columbia. Each record corresponds to a single, responding, in-scope sampled building. The records are comma-delimited, with fixed column positions, as described in Appendix A of the documentation. NOTE: Tabulations produced from these public use diskettes will not necessarily coincide with those from the reports. Several cases of unusually high natural gas consumption were discovered after publishing the Commercial Buildings Energy Consumption and Expenditure 1992 report. Data for these buildings have subsequently been imputed. In addition, some masking of the data was undertaken for confidentiality purposes. (see Technical Note 1 in the documentation) Documentation, that includes the file layout (Appendix A) and SAS formats (Appendix B) is in technical documentation file, CE92TECH.PDF (Acrobat version), also, CE92TECH.PS (Postscript version), CE92TECH.TXT (ASCII version) and CE92TECH.W51 (WordPerfect 5.1 version) are available upon requesting, Please contact David Chu at (202) 586-1121, or E-mail to dchu@eia.doe.gov. The files are GROUP-ZIP files. The procedure to UNZIP a GROUP-ZIP file, i.e. c920105t.zip, follows: (1) copy c920105t.zip onto your hard drive C, (2) on your hard C prompt, use PKUNZIP.EXE program, by typing PKUZIP C920105T -d, process will be performed. NOTE: All 18 ASCII format data files contain a value signified by the SPACE " " character. Software such as dBASE, LOTUS, QUATTRO PRO do not have the capability to directly handle such a SPACE " " value. All variables are delimited by COMMAs ",". The 18 data files (both ASCII and DBASE format) are organized by subject matter, and also contain the following core variables: (1) the building ID (the link between diskettes); (2) the adjusted sampling weight; (3) the variance stratum and pair member; (4) the Census region and division; (5) the square footage category; (6) the principal building activity; (7) the year constructed category; and (8) a set of variables indicating whether electricity, natural gas, fuel oil, district steam or district hot water was used in the building. It is hoped that the organization of the data among the files will allow many analyses to be conducted using one file.
