- Summary
- A field study directly measured the electric demand of 189 personal computer workstations for 1-week intervals, and a survey recorded the connected equipment at 1,846 workstations in six buildings. Each separate workstation component (e.g., computer, monitor, printer, modem, and other peripheral) was individually monitored to obtain detailed electric demand profiles. Other analyses included comparison of nameplate power rating with measured power consumption and the energy savings potential and cost-effectiveness of a controller that automatically turns off computer workstation equipment during inactivity. An important outcome of the work is the development of a standard workstation demand profile and a technique for estimating a whole-building demand profile. Together, these provide a method for transferring this information to utility energy analysts, design engineers, building energy modelers, and others. A life-cycle cost analysis was used to determine the cost-effectiveness of three energy conservation measures: (1) energy awareness education, (2) retrofit power controller installation, and (3) purchase of energy-efficient PCs.
