BOSTON, MA (08 April 2011) - ADD Inc's headquarters at 311 Summer Street have been selected as a winner of Mayor Menino's 2011 Green Business Awards. The awards recognize extraordinary performance related to sustainable environmental practices such as water conservation, waste management, the promotion of alternative transportation and transit, and energy conservation. Located in the burgeoning Boston Wharf District, ADD Inc's sensitive repositioning of 311 Summer Street was informed by the desire to incorporate strategic sustainable design practices while preserving the historic identity of this prominent building. The original structure, centered among commercial warehouses dating back to the early 1900's, was restored to full occupancy to create 60,000 square-feet of office and retail space. 311 Summer Street has achieved LEED CI Certification at the Platinum level from the US Green Building Council. Awards will be presented on Friday, April 15th at Atlantic Wharf.
