Bio-Solar House in Thailand
by Jan Krikke
It's an environmental dream: a self-reliant house that produces its own electricity, water, and cooking gas. Solar energy powers the air-conditioning, lights, and household appliances. Rain, dew, and condensation from the cooling system produce enough water for a family of four. Recycled water irrigates the garden, and surplus electricity is sold to the power company or used to drive an electric car 30 miles (50 kilometers) a day.
In Thailand, this dream has become a reality. A research team from Chulalongkorn University in Bangkok has built the country's first "bio-solar" house. Yet at first sight, the house hardly stands out among the other homes in a gated residential community.
The house has a heavy, slanting roof with overhanging eaves, sand-colored walls, a tastefully landscaped garden, and an attached carport. But that's where the similarities to its neighbors end. The bio-solar house is a high-tech, ecology-friendly version of what Le Corbusier called "a machine for living."
Buried in the garden are a photovoltaic system, biogas unit, air conditioner, condensation collection unit, water recycling equipment, filtering units, and storage tanks. Nothing in this home-cum-ecosystem goes to waste. Garden clippings (grass and leaves) and wet kitchen waste fertilize the small, organic vegetable garden. >>>
