ENERGY STAR® Qualified

Products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR specifications. The EPA establishes these specifications based on the following set of principles:

  • Product categories must contribute significant energy savings nationwide.
  • Qualified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
  • If the qualified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings, within a reasonable period of time.
  • Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by multiple manufacturers.
  • Product energy consumption and performance can be measured and verified with testing.
  • Labeling would effectively differentiate products and be visible for purchasers.
