Energy use in office buildings. Volume 1. Analysis of 1977 office building energy use as reported in the Building Owners and Managers Association Data Base

This report presents the results of Task IA of the Energy Use in Office Buildings Project: an analysis in tabular form of the 1977 office building energy use data base of the Building Owners and Managers Association (BOMA). BOMA's approximately 4000 members directly manage over 500 million ft/sup 2/ of commercial office space, which is approximately 16% of total commercial office building space. BOMA annually collects data on office building characteristics and operating performance for presentation in its Experience Exchange Report. Data are collected from BOMA member and non-member buildings electing to participate in the reporting process; and, in addition, a number of Federal, state, and local government buildings have been participating since 1977. Summaries of the data are published by BOMA on an aggregate basis; the summaries, which are developed on a city or regional basis, provide a benchmark for use by building managers in comparing the results of specific building operations with the industry's aggregate experience. Access to the 1977 BOMA data base was obtained under a subcontract with BOMA. Data for 1342 buildings - 1059 commercial office buildings and 283 government office buildings in the United States and Canada - were delivered. Of the 1059 commercial office buildings, 999 were located in the US. A total of 233 Federal-, state-, and local-government-operated buildings located in the US were also in the data base. Energy use data were reported by BOMA in terms of kWh of electricity, ft/sup 3/ of gas, gal of oil, and lb of steam. The data were converted to BTU's, and all building energy measures were expressed in terms of Btu/ft/sup 2/. Section II presents analysis for commercial office buildings; and Section III presents the analysis for government office buildings
