This is Park Passivhaus in Somerville, Massachusetts. The home was designed to the German Passivhaus standard and is currently being built on an urban infill lot. With modern detailing, a slender structure, and a shapely New England form by Placetailor, also the builder, Park Passivhaus will incorporate a Zehnder HRV, two Mitsubishi Mr. Slim mini-splits, and a high performance envelope with an 18″ double-wall cavity, blown-in cellulose, Makrowin windows and doors, Fakro skylights, ZIP sheathing roof, Siga tapes, Siga-Majvest membrane, Cedar and Alucubond cladding, etc. This is an excellent project to track, especially if you’re interested in Passive House detail.
