HUD Secretary Shaun Donovan, Congressman Mike Capuano, Boston Mayor Tom Menino and MassHousing's Tom Gleason were among those at a May 19 event to kick off work at Castle Square Apartments in Boston's South End.
Thanks to $54 million in MassHousing financing, Castle Square will undergo the largest deep energy retrofit in the country. Work on the 500-unit development will include a new, super-insulated building shell; high efficiency windows, lighting, appliances and mechanical systems; an insulated reflector roof; and aggressive air sealing.
Once the renovations are complete, the 192-unit Tremont Street midrise is expected to be the first building of its size to achieve energy savings of 72%. Natural gas consumption is expected to fall dramatically—as much as 71 percent for heat and 78 percent for hot water. Electricity usage is expected to decrease by up to 60 percent.
The financing agreement will also ensure that the property, originally built in the 1960s, will remain an affordable housing resource for years to come.
