To view an active solar home click on the thumb nail. These  assembled cube octahedron models are based on a scale of 4mm = one foot.  They demonstrate how a steep pitched roof may be integrated with a variety of housing designs to increase living space as well as provide a practical surface area for collecting sunlight energy.

It would measure 16 feet per side 32 feet across and 53 feet from the ground to the top of the triangular roof. The living space is about 3,000 square  feet. A 250 square foot solar collector system is mounted on the roof inclined toward the horizon at an angle of 60 degrees.

Cube octahedrons are added to the hexagonal units in a manner that allows all the roofs to join seamlessly. The living space of this is in excess of 4,500 square feet. The solar collectors cover an area more than 750 square feet.

This is the same Twin Hex-A-Frame viewed from the top.

hex3tf.jpg (19594 bytes)Here we have the famous "Hex Three" design made from three hexagonal units and toped with three interlocking cube octahedron roofs. Two 250 square foot collector arrays are mounted upon the roofs of the outside hexagonal units. The interior unit roof  has a solar greenhouse. Just imagine the joy of having your very own third story solar greenhouse in the dead of winter.

This allows more living space inside the building unencumbered by spiral staircases. The house measures 80 feet by 40 feet with a height of  33 feet. The Living is easy in this house with a floor area of. 6,500 square feet.

They would have to be spaced differently to maximize efficiency in a northern region. If all 12 collector arrays were used efficiently with a surface area of 3,000 square feet The savings in heating oil alone would exceed $5,000 per year. The interior of this structure is being used as a parking lot. With a little imagination the parking lot could be transformed into swimming pool and this cheesy motel could be transformed into a high class  thirty room resort with a living space area of about 15,000 square feet.
