Introduced in 2011, the “Energy Star Most Efficient” is a special designation that recognizes the best-of-the-best, most energy-efficient products within their categories. This label is intended to guide early adopters and environmentally-conscious consumers to products that represent the leading edge of efficiency, going beyond the standard Energy Star requirements.

The “Energy Star Most Efficient” designation was created to address a challenge that arose from the main program’s success: as the standard Energy Star label became ubiquitous in some product categories, it became harder for consumers to identify the truly exceptional products. This new label acts as a “top tier” within the existing program. The criteria for the Most Efficient designation are much more stringent and are updated annually to keep pace with technological advancements. Unlike the standard label, which recognizes a broad top percentage (e.g., 25%) of the market, the Most Efficient label might only apply to the top 5% or a smaller fraction. This serves two purposes: it provides a clear signal to consumers seeking the highest possible performance in energy savings, and it creates a powerful incentive for manufacturers to innovate beyond the baseline Energy Star specification. The program highlights specific product categories each year where significant efficiency gains are possible, such as clothes washers, refrigerators, and windows.

Precursors

  • the success and market saturation of the original energy star label
  • consumer demand for clearer differentiation among efficient products
  • tiered labeling systems used in other regions (e.g., a++, a+++ on the eu energy label)
  • the concept of “top runner” programs in countries like japan, which set standards based on the most efficient product on the market

Applications

  • premium product marketing for manufacturers
  • consumer choice for cutting-edge efficient technology
  • utility rebate programs offering higher incentives for top-tier products
  • driving innovation by setting a higher performance target for engineers
  • government procurement programs targeting best-in-class performance
