The Department of Energy’s Brookhaven National Laboratory has earned Long Island’s first LEED Silver rating. Brookhaven’s $12.6 million Research Support Building, designed by Farmingdale, New York-based Ehasz Giacolone Architects, earned 34 credits from USGBC, including the maximum possible for recycled-content and locally-sourced materials. General contractor E.W. Howell of Woodhaven, New York also diverted between 50 and 75 percent of the project’s construction debris from local landfills. The two-story, 65,000-square-foot building includes two different office wings that are connected by a glass atrium lobby, while the exterior is clad with metal panels.
