This is a floating home that is entirely self-sufficient and docked in Maastricht, Netherlands. Designed by Pieter Kromwijk and referred to as Autarkhome, the solar-powered project was built to the Passivhaus standard and is 10 times more energy efficient than the average dwelling of similar size.
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.
Hammer and Hand, a high-performance builder with offices in Seattle and Portland, recently announced the production of ultra-efficient custom doors for use with Passive House projects. The doors are designed and built in southeast Portland to the rigorous requirements of Passive House and help project teams avoid a potential economic premium and the carbon emissions associated with importing a similar product across the Atlantic from a European supplier. The company’s first door — shown in video here — was installed at their Karuna House project, which is pursuing PHIUS+ Passive House, Minergie-P-ECO, LEED for Homes Platinum, and net-zero energy designations (which I’ll explore in a subsequent article).
