Geometry lesson: this house is solar-effective.

Basic geometrical shapes--the square and triangle are integral to the cost-effective solar design of this house in Healdsburg, California. The square became the cubical form of the house, the triangle a wedge for the garage.

Architect Michael Rubenstein left three sides of the cube as vertical planes but cut into the east side to create the first-floor entry and an upstairs balcony.

To open the south wall, he used double-glazed sliding-glass doors; they let sunlight penetrate deep into the two-story living and dining rooms. Inside, tile floors absorb heat by day and release it at night. He chose standard-size doors because they cost less than custom, fixed-glass windows and can be opened to vent excess indoor heat. On the shady north side, he used only a few small windows.

At 45[deg.], one wall of the wedged-shaped garage provides a near-ideal angle for a dozen solar panels. They collect energy for a system that heats the house, the water supply, and a rooftop hot tub.
