Maryland Engineering Firm Specializing in Sustainability Services & Energy Solutions Recognized for Leadership in Energy Efficiency by U.S. EPA Three Years in a Row

Columbia, MD (3/26/2024)—Global Facility Solutions (GFS) is proud to announce that it has received the 2024 ENERGY STAR® Partner of the Year Sustained Excellence Award from the U.S. Environmental Protection Agency. As the highest honor among ENERGY STAR Awards, the Sustained Excellence Award recognizes organizations that have been an ENERGY STAR Partner of the Year for at least three consecutive years and have gone above and beyond the qualification criteria.

“As an energy and engineering services firm, energy conservation and sustainability have been a core focus area since I founded the company in 2006,” said Robert Calloway, P.E., Founder and CEO of Global Facility Solutions. “Sustainable operations and energy upgrades are more important today than ever, and we are excited to partner with Energy Star and the EPA to help drive energy efficiency and sustainability.”

Each year, the ENERGY STAR program honors a select group of businesses and organizations that have made outstanding contributions to energy efficiency and the transition to a clean energy economy. ENERGY STAR award winners lead their industries in the production, sale, and adoption of energy-efficient products, homes, buildings, services, and strategies. These efforts have saved more than 5 trillion kilowatt-hours of electricity over the past 30 years.

“President Biden’s Investing in America agenda creates unprecedented opportunity to build a clean energy economy, and private sector partners through programs like ENERGY STAR are leading the way,” said EPA Administrator Michael S. Regan. “I congratulate this year’s ENERGY STAR award winners for their innovation and leadership, in delivering cost-effective energy efficient solutions that create jobs, address climate change, and contribute to a healthier environment for all.”

Winners are selected from a network of thousands of ENERGY STAR partners. For a complete list of 2024 winners and more information about ENERGY STAR’s awards program, visit
