What does ENERGY STAR® certification signify?

  • It is the only environmental program in the United States that certifies energy efficiency based on actual, verified energy performance and objective measures, providing a guarantee of savings for plants within their industrial sectors.
  • It’s recognized by more than 90 percent of the American public and tied with the Good Housekeeping® seal as the most influential consumer emblem in the nation.
  • ENERGY STAR® certified buildings and plants use less energy because they are more efficient and therefore have lower energy costs than average performing plants. Earning and maintaining this certification demonstrates that a plant is well run and is better-than-average in managing its energy costs.
  • It demonstrates our positive relationships with neighbors and communities. Because this is a key point to obtain the recognition.
