Social Security Administration (New Bedford, MA)

The SSA's need for additional ground floor space encompassed the surrounding lawn so a green roof was designed to mitigate stormwater runoff. The insulating value of the green roof and the building envelope, including high-efficiency glazing and calcium silicate masonry units, resulted in a zero net gain for major heating, ventilating and air conditioning equipment in spite of doubling the square footage and occupancy.
