IMPs key to deep energy retrofit AT BOSTON'S CASTLE SQUARE APARTMENTS

摘要

Built in the 1960s, the 192-unit Castle Square Apartments complex was an energy hog, due largely to its inefficient enclosure. The quartet of seven-story buildings located in Boston's South End occupy an entire city block. The exposed concrete frame buildings are clad in brick veneer backed by concrete block infill, offering an R-value of just R-3.
