Vertically stacked and set into a hillside, Malibu 5 by Kanner Architects is a sustainable modern home constructed of environmentally friendly and recycled materials and designed to minimize energy use.

Conceived as a sustainable house that would make minimal use of the power grid, the house has photovoltaic panels on the roof, ground-level concrete floors act as heat sinks, pulling in the sun’s energy during the day and releasing it at night. The design has proven so successful that the residents are contributing energy to the local power grid.

Built as two, C-shaped rectangular bars — one two stories, one a single story over the garage — the house comprises four bedrooms and three bathrooms. The structures are separated by a courtyard. Rooms are open on two sides to provide cross ventilation. The home faces southwest to take advantage of coastal breezes, energy-providing solar gain and natural light. Large solar-protected windows produce light-filled rooms and minimize the need for artificial lighting, which is controlled with motion sensor light switches.

I am pretty sure that it has been featured on HGTV too…
