Saving energy is a way of life at Sub-Zero. The company believes in the importance of designing, manufacturing, and using products in an environmentally responsible manner. Sub-Zero strives not just to meet, but to exceed the standards for energy efficiency.

Today, the largest Sub-Zero refrigerator consumes less energy than a 75-watt light bulb. Numerous models are rated A+ or A++ energy-efficient by the European Union. It has numerous features that allow it to be energy efficient, such as a magnetic seal around all four sides of the unit that hold in cold air and hold down energy use. Its panels are vacuum-insulated to prevent the transfer of heat from outside of the refrigerator. It also has a variable speed compressor that keeps a Sub-Zero running only at the energy level it needs; it eliminates wasted operation by efficiently controlling motor speed.

Sub-Zero and Wolf’s manufacturing facility and processes also exhibit their efforts in minimizing environmental impact. They sort cuts of wires, copper, steel, and aluminum, so recycling can be possible. The company also recently installed a solar energy system in their facility in Goodyear, Arizona, which is estimated to avoid carbon dioxide emissions equivalent to nearly 160 million pounds of coal burned, or more than 330,000 barrels of oil consumed.*

A third-generation, family-owned company, Sub-Zero and Wolf appliances are manufactured in the United States using premium-grade materials since 1945. A leader in making energy-efficient products since 1970, Sub-Zero and Wolf continuously innovate groundbreaking technologies for the market while integrating sustainability initiatives throughout the whole company.
