Electronic office equipment represents a fast-growing but poorly understood component of the ''other'' end use in commercial buildings. We analyzed technical data and market projections to characterize the electricity usage and efficiency potential for this equipment. There were no published data on actual power consumption of office equipment, so we metered selected pieces of equipment, for comparison with nameplate ratings. Measured power use was typically 20--40% of nameplate ratings. Power use varies for similar equipment; in particular, desktop PCs use about ten times the power of equivalent laptop models. Typical daytime loads for office equipment are about 10--20 W/m/sub 2/, roughly equal to lighting loads in a well-designed new office. Future load growth depends on many market and technical factors; US office equipment electricity use in 1995 could range from 130 TWh (''market saturation'' of current technology with expanded use of computerized printing) to about 25 TWh if today's most efficient hardware and operating systems became the market norm. 45 refs., 5 figs., 4 tabs.
