Boston's Castle Square Apartments achieves 72% energy reduction after retrofit

December 19, 2012

Earlier this year, Castle Square Apartments in Boston completed a deep energy retrofit after a complex renovation process that lasted two years. A deep energy retrofit is defined as a renovation with energy savings greater than 50%, but the retrofit work at Castle Square Apartments reaped a whopping 72% energy usage reduction. The retrofit, which cost more than $8 million, included a "five-inch super insulated shell," an insulated reflective roof, high-efficiency windows, and extensive air sealing.

The U.S. Green Building Council (USGBC) has awarded the project LEED Platinum Certification. The 540,000 sf mixed-use property in Boston’s vibrant South End neighborhood includes townhouses and affordable housing units. Built in the 1960s, the property is a good example of affordable housing developments that were built during that time with minimal to no energy-efficient construction techniques.
