SAE International to Certify Vehicle Air Conditioners for Environmental Performance

Warrendale, PA (August 23, 2005) - Ever been low on gas, stuck in summer after-work traffic and wondered about the energy efficiency of your vehicle's air conditioner?

A new program to certify motor vehicle air conditioners announced today by SAE International will answer such questions. Certification is available immediately for leak tightness as tested by SAE J-2727 (June 2005)*. Certification of energy efficiency will be available as soon as an SAE technical standard is approved in 2006. SAE Certification uses the acronym "I-MAC" in reference to Improved Mobile Air Conditioning.

SAE certification supports the goals of the Mobile Air Conditioning Climate Protection Partnership to reduce refrigerant greenhouse gas emissions by at least 50 percent and to reduce the greenhouse gas emissions of fuel use to power air conditioning by at least 30 percent.

The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) estimates that more than 5 percent of gasoline used in the United States is for vehicle air conditioning and that refrigerant emissions contribute a comparable amount to global warming.

The J-2727 certification will be conducted in a similar manner to the Certified Power program recently announced by the Society of Automotive Engineers and the automobile industry. In that program, engine manufacturers determine horsepower from tests verified by a third party witness to be in accordance to the SAE Test Standard. SAE maintains the official database of certified results, which is available to the public.

The SAE I-MAC certification program will be guided by an international board of advisors including representatives of vehicle manufacturers, component suppliers and environmental authorities.

The following experts will serve on an interim technical board to help assure smooth and successful operation of the certification process: Stephen O. Andersen (US EPA), Ward Atkinson (SAE Climate Control Technical Committee), Denis Clodic (Ecole des Mines de Paris), Paul Hughes (California Air Resources Board), and Rowland Hwang (Natural Resources Defense Council). In addition, representatives from the world automobile manufacturers, air conditioning suppliers and European governmental bodies have been invited.

* SAE Standards in first reference must include month and year of publication.
