San Ardo Ranch House
This house for a ranch manager with modern sensibilities uses modern forms and traditional materials such as corrugated metal siding.
The house is a passive solar design, with owner-erected SIP panel walls and roof, which went up in 5 days. Interior walls are metal studs. The SIP panels provide enough insulation to provide comfort in a harsh climate with freezing days in winter and 100 degree days in summer. Winter heating is provided by in-slab hydronic water heating, and no air conditioning is necessary.
Overhang dimensions were tuned using 3D modeling software to shade glazing areas when desired, and operable high windows allow night time cooling. High mass walls and floor store and re-release heat.
The SIP panels that compose the exterior are extremely light compared to conventional framing, and provide approximately 3 times the earthquake resisting strength, an important consideration as the site is located very close to the San Andreas fault line.
