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 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).
