Energy Star Specification for Dishwashers Revised

The Environmental Protection Agency recently finalised a revision to the Energy Star specification for residential dishwashers. Under the new criteria, certified standard dishwashers will use on average approximately 12 percent less energy and 25 percent less water than required by minimum efficiency standards. Compact dishwashers will deliver nine percent energy savings as well as 11 percent water savings over conventional compact products. If all residential dishwashers sold in the United States met these new requirements, the utility cost savings would grow to more than US$545 million each year and more than six billion pounds of annual greenhouse gas emissions would be prevented, equivalent to the emissions from more than 650,000 vehicles.

The EPA notes that for the first time since 2013 the Energy Star label will recognise a selection of highly efficient compact dishwashers. A test method for cleaning performance is also expected to help the EPA ensure that certified dishwashers save energy and water without sacrificing on the functions that consumers expect. In addition, the new specification establishes the first set of optional “connected” criteria for residential dishwashers. Dishwashers with connected functionality will offer consumers new convenience and energy savings features, such as alerts for cycle completion and/or recommended maintenance, as well as feedback on the energy use of the product. These products will also be “smart grid” ready, giving consumers the option to connect their dishwasher with their local utility to save money on their energy bills, where those services are offered, and also facilitate broader electric power system efficiency.

Energy Star is a voluntary labelling programme designed to identify and promote energy-efficient products to reduce greenhouse gas emissions. The Energy Star label is now available on more than 40 different kinds of products, including home electronics, clothes washers, dehumidifiers, dishwashers, refrigerators and freezers, room air conditioners, commercial fryers, commercial hot food holding cabinets, commercial solid door refrigerators and freezers, commercial steam cookers, computers and other office equipment, and lighting.
