Karuna House, a single family residence which stands on the hilltops of Yamhill County, Oregon has received the Passive House (PHUIS+), Minergie-P-ECO and LEED for Homes Platinum certifications. It is the only house in the world to receive all these hallmark certifications of green building. The house was designed by Holst Architecture and built by the company Hammer & Hand.
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.
One thing I’ve noticed is the fact that home building is changing in a big way. In order to capture what’s going on across the country, I thought it would be interesting to talk with influencers and innovators about things like tiny houses, prefabrication, sustainable design, high performance construction, and home technology. For this first interview, I was able to exchange emails with Sam Hagerman, co-owner of Hammer & Hand and president of the Passive House Alliance US, on the topic of ADUs and Passive Houses.
