Notes recent research by ASHRAE into measuring actual heat gain and radiant and convective split from equipment in buildings and the application of the developed methodology to a wide range of equipment. Goes on to present generalized guidelines based on the results of all previously mentioned research for office equipment. Discusses the disparity between nameplate vs. measured power consumption. Presents findings based on the research for heat gain from computers in general, from monitors, laser printers, copiers, and miscellaneous equipment. Discusses the significance of usage diversity. Deals with heat gain per unit area. Considers the data presented will be relevant for several years, and that the information should be useful for engineers performing cooling loads or energy analyses.
