CBRE Group, Inc. (NYSE:CBG) announced that it has acquired Environmental Systems, Inc. (ESI), a leading systems integrator and provider of energy management services in the United States.

ESI develops innovative solutions that enable commercial property occupiers and owners to efficiently manage their building systems and remotely monitor and analyze energy usage in real time to identify and achieve potential savings. ESI is providing analytics-driven managed services on over 180 million sq. ft. of facilities at over 2,800 sites throughout the U.S.

“ESI complements our existing suite of facilities-related outsourcing services. Our clients increasingly look to us to leverage new and existing controls -- and the data that can be extracted from systems -- and remote monitoring to drive greater energy efficiency,” said Bill Concannon, chief executive officer, Global Corporate Services, CBRE. “This is a core strategy and growing capability for CBRE. ESI's professionals will enhance our expertise and service offering in energy & sustainability management.”

Founded in 1986, ESI, based in Brookfield, Wisconsin, offers a wide range of technology, solutions and services in the areas of systems integration, building automation, energy management, advanced analytics, security systems, and support services. The company serves a wide range of facility types including office, retail, industrial, critical environments, health care and education.

The acquisition of ESI follows CBRE’s announcement of a definitive agreement to acquire the Global WorkPlace Solutions (GWS) business of Johnson Controls, Inc., expected to close in the late third quarter or early fourth quarter of 2015. GWS is a market-leading provider of integrated facilities management solutions for major occupiers of commercial real estate. Both transactions underscore CBRE’s commitment to provide global, industry-leading facilities management solutions -- including energy & sustainability products and services -- for its clients.

“We value long-term relationships with our customers and work closely with them to reduce costs, improve efficiency and maximize their facility investment,” said Paul Oswald, president, ESI. “Joining CBRE’s high-quality, integrated Energy & Sustainability service offering will further our goal of providing superior solutions that meet the ever-evolving needs of our clients.”
