Three Cummings Properties buildings recently earned Energy Star certification by achieving strict energy performance levels set by the U.S. Environmental Protection Agency. The Woburn-based commercial real estate firm reportedly has more than 2 million square feet of space with this distinction.

Cummings’ 10 certified properties, now including 8 Cabot Road in Woburn, 142/144 North Road in Sudbury, and 800 Cummings Center in Beverly, each outrank 75 percent of similar facilities nationwide for energy efficiency.

Built in 2010, 8 Cabot Road was designed to meet LEED standards, which signify environmentally friendly design and construction.   It has many "green" features, including high efficiency lighting and water source heat pumps, as well as motion sensors and variable frequency controls for its HVAC systems. The building also hosts a 30KW solar installation that produces about 50 percent of the building’s common area electric load.

The Sudbury property includes 142 North Road, built in 1960, and its annex, 144 North Road, built in 2009 to LEED standards.  Cummings Properties performed several energy efficiency upgrades in recent years on the original building.
