Community Roots Housing: Brewster Apartments

Solutions

In keeping with the organization’s goal of operating an environmentally sustainable portfolio, Community Roots Housing (CRH) was motivated to make Brewster an energy-efficiency project showcase. While the installation of high-performance windows and doors served the dual purpose of mitigating noise from the abutting construction project and increasing the performance of the building envelope, the replacement of Brewster’s gas wall furnaces with an electric split heat pump (ASHP) system was the single most substantial energy-saving measure. In total, four different energy upgrades were installed resulting in a source energy reduction of 26%.

The ASHP specifications and other project details include:

ASHP, SEER rating of 18 and a coefficient of performance of 3.4.
Replacement of 115 apartment unit windows and 2 entry windows with new VPI Quality Windows with a U-factor ≥.26 and a solar heat gain coefficient ≥ .18.
Replacement of the east and west entry doors with new metal-clad doors, glass, and hardware.
New fiberglass blown-in insulation with an R-value of 49 in the top floor attic.
