ENERGY STAR Most Efficient 2020 - Proposed categories and criteria

The ENERGY STAR program continues to recognize the highest performers in energy efficiency for recognized products by extending and expanding the ENERGY STAR Most Efficient designation for 2020.

Energy efficiency advocates throughout North America can continue to raise the bar on energy efficiency by leveraging ENERGY STAR Most Efficient 2020 product information that helps consumers find and purchase the “best of the best” among recognized product categories.

2020 Product categories and recognition criteria

For 2020, the U.S. Environmental Protection Agency (EPA) intends to continue to highlight all 14 of the product categories currently eligible for ENERGY STAR Most Efficient recognition, and introduce room air conditioners to the portfolio for a total of 15 categories. The proposed criteria for dehumidifiers will be shared with stakeholders this fall.

The proposed recognition criteria for 2020 were based on an analysis of currently certified ENERGY STAR models as well as engineering analysis conducted by the U.S. Department of Energy. The results of the analysis indicated that for many categories existing recognition criteria remain reflective of the "best of the best". As a result, Most Efficient 2019 efficiency criteria is being extended into 2020 for boilers, furnaces, central air conditioners and air source heat pumps, dishwashers, geothermal heat pumps (GHP), refrigerators/freezers, televisions, and ventilation fans.

In addition to adding criteria for room air conditioners, additional product sub-types are also being proposed for recognition for refrigerator/freezer and windows*.

*The Most Efficient residential windows specification for Canada is developed and published by Natural Resources Canada (NRCan). For 2020, the qualifying criteria will be more stringent and include sliding glass doors. For further information, please e-mail ENERGY STAR Canada.

The monitor criteria has also been revised and modest revisions are being proposed to ceiling fan and dryer criteria. Lastly, it is being proposed to allow partners to indicate the availability of consumer features such as soil sensing on the ENERGY STAR Most Efficient product list for dishwashers, refrigerators, and dryers.

Additional information regarding the roll out of ENERGY STAR Most Efficient 2020 recognition will be provided with the finalization of these criteria. Products recognized in 2019 that meet the ENERGY STAR Most Efficient 2020 criteria will automatically receive recognition.

A stakeholder webinar will be held on August 7, 2019 from 2 to 4 pm EST to discuss the proposed recognition criteria. To participate in this webinar, please register here by August 6th. Please share written comments no later than August 22, 2019 with It is expected that recognition requirements will be finalized in August.
