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). More about custom Passive House doors.
James Green is an aircraft structural engineer who found a creative solution when designing a home for a remote site in Turkey (that wouldn’t allow a concrete foundation). Green decided to structure the house around a shipping container with an extended skeleton of removable frames. Seeing more potential, he then patented the idea and teamed up with architect Matthew Coates of Coates Design Architects in order to deploy “Eco-Pak” as modular and sustainable housing.
This is a green home in the Wallingford neighborhood of Seattle and another energy-efficient renovation by Green Canopy Homes. The company — which also renovated The Sentinel — is targeting Built Green 3 Star certification with help of comprehensive air sealing, extra foam and rigid insulation, Energy Star windows, a home electricity monitor, heat-pump water heater, Energy Star ductless heat pump, and CFL lighting.
The concept of using off-site fabricated modules for core elements of a home is not necessarily new. In fact, most recently Proto Homes introduced a hybrid-prefab system with the Proto Core, which is a chase for mechanical, plumbing, and electrical. It’s also being used in the form of “wet-cores” for The House of the Immediate Future with Habitat for Humanity (Seattle/South King County) at the Seattle Center.
Last week, Greenfab was awarded LEED Platinum certification for this modular home, a contemporary residence located in the Jackson Place neighborhood of Seattle. It’s the first prefabricated, modular home in Washington to obtain this level of LEED certification and the design is part of Greenfab’s 1300 Series now available nationally.
