BOSTON--Deep-energy retrofits use a variety of green building techniques to slash energy consumption by as much as 70 percent. The Castle Square low-income housing complex in the South End of Boston is applying those methods in a renovation of the 500-unit complex, making it one of the largest deep-energy retrofits in the U.S., according to developers.
Seen here is the insulation that will be placed on the brick exterior of the building that will seal the building and add an R-40 thermal resistance value. The apartment's tenant organization is looking forward to a new facade which will help it better fit into the neighborhood.
