Procurement PolicyOffice Equipment and AppliancesOffice equipment accounts for 26 percent of electricity used in office buildings - more than the entire lighting system (22 percent) and almost as much as the chilled water subsystem (28 percent). Yet this is the easiest area in which to achieve energy efficiency savings - simply retire outdated or malfunctioning equipment and replace with ENERGY STAR-qualified models. Work with in-house procurement staff to develop company guidelines for purchasing ENERGY STAR-labeled equipment and appliances. Labeling and information are available for computers, copiers, power adapters, fax machines, laptops, monitors, multifunction devices, printers, scanners, and water coolers as well as appliances like dehumidifiers, refrigerators, freezers, and room air conditioning units. Inefficient office equipment typically is coupled with inefficient power supplies, also referred to as power adaptors. ENERGY STAR estimates that there are 1.5 billion power supplies in the United States, or about five for every one person. Unfortunately, these power supplies waste roughly 30 to 50 percent of the 207 billion kilowatt-hours of energy passing through to electronic equipment. In other words, the printer in your office could waste half the electricity paid to operate it, just like the telephone, the computer, the coffee pot, and so on. To minimize this energy waste, check around the office for ways to reduce the total number of power supplies. Consider purchasing a multifunction device, for example, rather than separate scanner, printer, and fax to reduce the total number of adapters. Use surge protectors for all plugs, turning off the surge protector when the office is unoccupied. ENERGY STAR is developing a rating system to address power supplies, which should soon be available and will help in purchases of new equipment. No-Cost Energy Saving Tips
