Yakima Net Positive

A southeast facing slope overlooking the Yakima Valley set the stage for this passive solar design. There is a ground source loop to provide year-round thermal comfort at almost no cost of operation, and the south facing roof is topped with enough Solar PV panels to generate all the home’s electrical needs on an annual basis.

Healthy, resilient finishes are used throughout the home, from clay plaster walls to stained concrete floors. Cork flooring creates softness underfoot in the kitchen and dining areas, and porcelain tile is featured in the showers. Reclaimed wood from a local deconstructed apple shed adds interest in key locations. Reclaimed corrugated metal roofing from the building was used as accent siding on the exterior, along with natural lime stucco and cement board lap siding.

For future health considerations, the main level is fully wheelchair accessible, and everything is ready for an elevator to provide easy transport from the lower level garage and shop.

Update: It has been over two years since the owners moved into their new home, and they have not had a single energy bill. They report that the indoor temperature is comfortable year-round — warm in the winter, and cool in the summer.
