DOE Sets New Energy Test Procedures for Portable ACs, Favours Tougher Standards for Water Heating Equipment

The U.S. Department of Energy has established new mandatory energy test procedures for portable air conditioners in a new regulatory appendix, which will be used to determine the seasonally-adjusted cooling capacity and combined energy efficiency ratio for these products. The energy test procedures are based on industry standards, with several modifications to ensure they are representative of typical use and to improve accuracy and repeatability while minimising test burden. The final rule changes will be mandatory for representations of energy use or efficiency on or after 28 November 2016.

Separately, the DOE has tentatively concluded that there is clear and convincing evidence to support more stringent energy conservation standards for several classes of commercial water heating equipment. The DOE did not consider more stringent standards in this action for commercial oil-fired storage water heaters, whose standards were recently amended. Therefore, the agency is proposing amended standards for certain commercial water heating equipment and will accept comments, data and information from interested parties by 1 August.
