“…However, users may disable features for various reasons, such as slow recovery times from low-power modes or (for PCs) incompatibility with computing networks. Metering of ENERGY STAR computers suggests that less than ten percent have their power-saving features enabled (Roberson et al 2004). To account for the enabling factor, we calculate separate UECs for products that are enabled and products that are not enabled and then calculate a weighted average UEC based on our estimate of the enabling rate.…”

“…Another key input was the percent of units left on after working hours. Recent nighttime audits of office buildings found that 64 percent of computers, 68 percent of CRT monitors, 82 percent of LCD monitors, 85 percent of laser printers (77 percent of all printers), 52 percent of copiers and 80 percent of MFDs were left on at night (Roberson et al 2004). Three years earlier a similar study found that 56 percent of computers, 68 percent of monitors, 75 percent of printers and 82 percent of copiers and MFDs were left on at night (Webber et al 2001).…”

ENERGY STAR® is a voluntary labeling program designed to identify and promote energy-efficient products, buildings and practices. Operated jointly by the Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE), ENERGY STAR labels exist for more than thirty products, spanning office equipment, residential heating and cooling equipment, commercial and residential lighting, home electronics, and major appliances. This report presents savings estimates for a subset of ENERGY STAR labeled products. We present estimates of the energy, The target market penetration forecast represents our best estimate of future ENERGY STAR savings. It is based on realistic market penetration goals for each of the products. We also provide a forecast under the assumption of 100 percent market penetration; that is, we assume that all purchasers buy ENERGY STAR-compliant products instead of standard efficiency products throughout the analysis period.

“…ENERGY STAR imaging equipment must meet either a maximum total energy consumption (TEC) We model residential and office settings separately due to different usage patterns. Commercial operating patterns are derived from equipment audits at various locations that provide time spent in each operating mode, nighttime turn-off rates, and power management success rates (Piette et al 1995;Nordman et al 1998;Webber et al 2001;Roberson et al 2004). Operating patterns for residential computers are derived from hours-of-use monitoring for a large sample of residential computer users (Media Metrix 2001).…”
