The U.S. Department of Energy on Thursday recognized Atlanta-based Arby’s efforts to reduce energy consumption by 20 percent in all its stores over the next 10 years.

The fast-food giant is taking part in the Energy Department’s Better Buildings Challenge, which is pushing to double American energy productivity by 2030 through energy saving commitments and investments. More than 250 organizations are participating.

To reach its goal, Arby’s is retrofitting lights, upgrading HVAC systems and improving efficiency in hot water use and refrigeration. The company has reached 38 percent energy savings at its flagship store on Howell Mill Road in Atlanta.

“Arby’s energy efficiency work is proof that brands can set ambitious energy savings goals,” said David Danielson, assistant secretary for energy efficiency and renewable energy. “Even with historically energy-intensive buildings like restaurants, Arby’s is committed to developing innovative and successful models and approaches with restaurant owners interested in replicating gains in efficiency.”

Said Arby’s Chief Executive Officer Paul Brown, “Our team members are empowered by the energy savings we’ve seen and we’re excited to continue to find new avenues to reinvest the cost savings, as well as be responsible stewards of the environment.”
