能源之星最高效称号

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.
