Finch is an early example of the Commonwealth’s commitment to dramatically decreasing energy use in large, affordable housing projects. “Firsts” always make for challenging projects, especially when collaborating among the various consultants and disciplines. Petersen Engineering worked closely with the architect, owner, and contractor to meet the Passive House certification requirements, and presented at several building tours during construction, sharing design techniques and lessons learned.
Heating and air conditioning for Finch Cambridge are provided by variable refrigerant flow (VRF) air source heat pump (ASHP) systems that allow for a simultaneous heating and cooling system with no fossil fuels.
