AC Efficiency Standards Increased by 6 Percent

A ruling issued Monday by the United States Department of Energy (DOE) will require that states certify that their building codes meet or exceed requirements in an energy standard developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) for air conditioners.

Atlanta, Georgia – July 19, 2002 [SolarAccess.com] Air conditioners account for 10 percent of the energy used in commercial buildings in the United States. The standard, Energy Standard for Buildings Except Low-Rise Residential Buildings, contains requirements for efficiency of heating, ventilating and air-conditioning (HVAC) systems. The standard, now referenced in the federal Energy Conservation and Production Act, saves up to 6 percent more energy than the previous requirements, according to the DOE. The ruling coincides with the 100th anniversary of the invention of modern air conditioning. On July 17, 1902, Dr. Willis Carrier submitted designs to a printing plant in Brooklyn, N.Y., for equipment to control temperature, humidity, ventilation and air quality.
