Better Buildings Challenge partner Digital Realty Trust Inc., a data center solutions and services provider based in San Francisco, CA recently earned the U.S. Environmental Protection Agency’s ENERGY STAR certification for its facility in Lithia Springs, Georgia. The certification acknowledges that this complex operates in the top quartile of data centers nationwide in terms of energy efficiency, and contributes 35% fewer greenhouse gas emissions than similar non-certified facilities within the United States.
Digital Realty earned the ENERGY STAR distinction by employing a combination of retrofit projects and best energy practices, including the installation of modulating electronically commutated fan motors on critical air conditioners, the use of variable speed pumping, and raised supply air set points to improve cooling efficiency. The company collaborated with the Lithia Springs data center’s primary customer, to implement these energy management efforts, and plans to look for similar partnership opportunities with customers at its other facilities.
