Liebherr Appliances is proud to announce that a total of 9 models have earned the coveted ENERGY STAR® ‘Most Efficient 2020’ designation, being the only brand with a Fully Integrated freezer achieving these standards.


The ENERGY STAR® ‘Most Efficient’ designation is an initiative of the U.S. Environmental Protection Agency and the U.S. Department of Energy designed to raise the profile of the highest energy-efficient products in their categories among those that have earned the ENERGY STAR® label. The ‘Most Efficient’ recognition furthers ENERGY STAR®’s efforts to help North American consumers reduce their utility bills while helping to protect the environment.

As an industry trailblazer in green manufacturing, Liebherr Appliances aims to manufacture highly efficient products with the least damaging effect on the environment. Liebherr Appliances is committed to offering energy-saving kitchen solutions while contributing to an overall smaller carbon footprint.

“We are proud to continue receiving this honorable distinction each year, as we are able to offer more ‘Most Efficient’ models to our environmentally conscious consumers, like our expansion on our undercounter models,” said Alex Squarize, Divisional Director of the Refrigerators and Freezers Division of Liebherr USA, Co. “We are honored that Liebherr is among the premium brands that qualified for this prominent designation, representing the best of European sustainable manufacturing. This showcases our investment in the environment, producing only top-of-the-line products that meet or exceed ENERGY STAR® standards.”

All Liebherr refrigerator-freezer combinations use the natural and environmentally-friendly R600a refrigerant, which reduces greenhouse gas emissions, thereby reducing the impact on ozone depletion and global warming. In combination with R600a refrigerants, variable speed compressors offer quiet operation and minimal electrical ‘surge’ at start-up, further increasing energy efficiency.

Additional energy-saving features include:

  • Liebherr’s state-of-the-art DuoCooling refrigeration system which allows the cooling and freezing compartments to be accurately controlled independently of each other, providing superior performance and efficiency, along with advanced food preservation.
  • The use of LED lighting in both compartments, which uses less energy than conventional appliance lighting. LED lights produce less heat than conventional lighting, reducing the need for the appliances to cool frequently.
  • A Door Ajar alarm ensures that doors are closed properly, halting cool air from escaping and reducing wasted energy.
  • Freezer Frost-safe bins trap in cold air even when the door is open, reducing the need for further cooling.
