Field Surveys of Office Equipment Operation Patterns
*End-Use Forecasting Group
This paper presents the results of 11 after-hours walk-throughs of offices in the San Francisco Ca. and Washington D. C. areas. Ther primary purpose of these wolk-throughs was to collect data on turn-off rates for various types of office equipment (computers, monitors, printers, fax machines, copiers, and multifunction products). Each piece of equipment observed was recorded and its power status noted (e.g. on, off, low power). Whenever possible, we also recoreded whether power management was enabled on the equipment. Ther floor area audied was recored as well, which allowed us to calculate equiment densities.
We found that only 44 percent of computers, 32 percent of monitors, and 25 percent of printers were turned off at night. Based on our observations we estimated success rate of 56 percent for monitor power mamangement and 96 percent for enabling of power mamangemetn on printers.
