Fine Homebuilding HOUSES 2019 Best Energy Smart Home award winner (click for article)

New Passive House on a hilltop in Carnation, WA.  Three bedrooms, two baths with an attached four-car garage.  The aesthetics were inspired by rural barns which created an efficient building form to achieve the Passive House standard. This project was built by the homeowners themselves over the course of five years.

Net positive energy is achieved through super insulation, triple glazed windows, rigorous air sealing, a Heat Recovery Ventilator,  solar hot water, and PV panels.  The 8,800 gallon tank collects rain water from the roof to supply 100% of potable uses inside the house, the first house in King County (greater Seattle) 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+.

Roy Passive House

New custom house on blueberry farm in Moxee, WA.  Four bedrooms, three baths plus playroom loft.  All rooms except the loft are on one level allowing for aging in place.  The house orientation and room layout were determined by the principles of feng shui.

Natural materials are employed throughout, featuring stained concrete floors, clay plaster walls, and exposed wood roof rafters.  The exterior siding is flame blackened (shou sugi ban technique) to protect it without the need for painting.

Energy use reduction is achieved through super insulation, triple glazed windows, Heat Recovery Ventilator, mini split heat pump, solar hot water, and PV panels.  Certified Passivhaus by PHI.
