Rubissow Farmhouse
Napa, CA

OSA designed this 1,200 square foot passive solar residence on a limited budget. The local climate is ideal for passive solar — evening breezes help cool the interior during the summer while solar radiation warms the stained concrete slab floor during the winter. The major rooms are oriented south for optimum solar exposure, while the concrete floor and PISE earth walls provide thermal mass. Windows allow for a wealth of natural light as well as frame the spectacular views. On the exterior, the earth walls contrast with the horizontal cement fiber siding and OSB wood panels. Inside, tall redwood plank doors made from an old water tank separate the private rooms from the central great room.
