Fire load and live load data obtained from a survey of 23 office buildings located in various regions throughout the United States are presented. The survey design is described including the characteristics of the building population used to select the sample. Data are presented on the magnitude and distribution of the loads. Information is also included on the characteristics of office loads such as the type of items (furniture. equipment, etc.) and their properties (material type, dimensions, exposure, etc.). Statistical summaries of the data and a determination of the building and occupancy characteristics affecting these loads are presented. The data do not indicate any significant differences between the loads in private and government buildings. Similarly, geographic location, building height, and building age were not found to have a significant influence on load magnitude. The use of the rooms surveyed, however, did affect load magnitude. A mathematical model developed from a regression analysis of the survey data is presented for calculating fire loads and live loads in offices. The data presented may be used to evaluate current requirements for design loads for buildings.
