Two new buildings at 175-185 Wyman St. in Waltham have been certified LEED Gold by the U.S. Green Building Council (USGBC).

All 39 construction phase credits were accepted, resulting in a perfect review score. The project also received all five Innovation in Design credits available.

Owned and operated by Hobbs Brook Management, the 335,000-square-foot, two-building complex was designed by architecture and interior design firm Margulies Perruzzi Architects, and built by Columbia Construction Co.

"We are pleased to achieve LEED Gold certification for our two new Class A office buildings," said Donald Oldmixon, first vice president of real estate, construction and leasing for Hobbs Brook Management. "As the owner and property manager, our goal is to build quality, sustainable office space for long-term tenants. We made each design and construction decision with an eye towards sustainability, and consider this achievement validation by the USGBC that our efforts were a success."

The project included an integrated green cleaning program, landscaping, high-reflection roofing, preferred parking for hybrid-vehicles, and shower facilities for bicycle commuters. The stormwater quality treatment system was incorporated into drainage and uses a pond that doubles as a landscape feature to clean water before it heads to the Cambridge Reservoir while additional stormwater runoff collected on site will be used to irrigate the landscaping.

Special consideration was also taken with the HVAC units and the energy efficient cooking and cooling equipment in the dining facility. The project featured a 40 percent water-use reduction and a 22 percent optimized energy performance during the design, engineering, and construction phases, with the intention of reducing energy costs to future tenants.
