Air conditioning systems constitute a major portion of the first-costs and the operating costs of office buildings. Therefore, before any air-conditioning system can be built, an accurate estimate of the air-conditioning load is required. The total air-conditioning load is made up of several components including solar, lighting, people and equipment. The equipment load contribution to the overall air-conditioning load has increased over the years as offices have become more automated. In today's modern office building, the equipment load is primarily attributable to automatic data processing (ADP) equipment such as computers and printers. To get the accurate data that engineers need, a study was conducted to make measurements of the power consumption of ADP equipment. The study described here included measurements of individual items of equipment to determine the maximum heat output. Also measured was the consumption of all equipment in an area that was connected to a single electric panel. This measured data, along with a detailed survey of the equipment connected to each panel, was used to determine actual maximum heat loads and actual diversity factors.
