Design

    Trinity Episcopal Church campus, protected as part of a historic district, includes the Chapel and the Elwell Cottage dating from the 19th century as well as the Church designed by Pietro Belluschi in 1962. Amid these structures, the design inserts new social program centered by the Parish Hall, a tall room sunlit by day and set aglow at night by pendant opal glass orbs. Otherwise concealed by the old structures, the addition extends an entry wing toward River Street, matching the proportions and colors of the stone Chapel, but clad in cedar rainscreen siding and incised by a cantilevered porch and glazed lobby. Both circulation and social space, the lobby looks across a narrow garden to the Chapel’s buttresses and stained glass lancets. A similar paved micro-court also reaches deep into the center of the complex, separates new fabric from old, and infuses new space with daylight and garden views of the surrounding campus architecture.

Sustainability

  • The new wing is enclosed by super-efficient envelope meeting Massachusetts Stretch Energy Code
  • The addition subsumes the old boiler room, inserting a new super-efficient heating plant burning natural gas to improve Trinity's carbon footprint and operating budget
  • Voluminous fresh air needs are mitigated by energy-efficient HVAC system: CO2 levels trigger fresh outdoor air intake that is tempered with energy recovered by heat-exchangers from the exhausted airstream
  • Sustainably harvested, high recycle-content, and low VOC building materials used throughout
