New York City’s new $50 million Office of Emergency Management (“OEM”) headquarters in Brooklyn, which I wrote about back in December, earned its LEED Silver rating from USGBC on Wednesday. The four-story building was designed by Swanke Hayden Connell Architects and is located on Cadman Plaza East near the Brooklyn Bridge. The project was funded entirely by the federal government and is the first city agency headquarters to achieve any level of LEED certification.
