Results are presented of an effort to develop comprehensive and reliable energy consumption data for office buildings. A survey was conducted of readily available energy consumption data and the literature that describes the factors which drive energy use in such buildings was analyzed. Information on heating, ventilating, and air conditioning (HVAC) systems was assembled. A number of building energy use simulation programs were reviewed to determine their suitability for estimating energy consumption by function and the effects of tradeoffs in building design and operating parameters on building energy use. Simulations using the AXCESS program were conducted. The 1975 data base of the Building Owners and Managers Association (BOMA) was obtained and analyzed. Data describing energy use on a regional and national basis were developed, and regression equations based on these were obtained. The ability of these equations to predict average energy use was then confirmed by applying them to four office buildings not in the BOMA data base. A number of proposals for the further improvement of the equations were developed, including additional data collection. Specifically, the survey of actual and simulated data on a regional basis is reported in Section 2. HVAC systems are discussed in Sections 3 and 4. BOMA obtains annual data on about 1000 buildings covering such items as location, floor area, height, age, average occupancy rate, average number of employees, types of tenants, type of air conditioning, and energy consumption by fuel and the description and analyses of the BOMA data are presented in Sections 5 and 6.
