New Passive House on a hilltop in Carnation, WA. Three bedrooms, two baths with an attached 4 car garage. The form and aesthetics are inspired by rural barns which provide for an efficient building envelope to achieve the Passive House standard. This project was built by the homeowners themselves over the course of 5 years.
Energy use reduction is achieved through super insulation, triple glazed windows, Heat Recovery Ventilator, solar hot water, and PV panels. The 8,800 gallon rainwater tank collects water from the roof to supply 100% of potable uses inside the house, the first house in King County to do so. Low toxicity materials were used throughout the building, most lumber is certified FSC, and the building is a Certified Passivhaus by PHIUS+.
