Down to Earth House

Since the mid 70's many scientists, from biologists to engineers to physicists try to discover different ways of improving climate control within a building, minimizing the need need for artificial heating and cooling.

People can use high tech solutions have been developed - such as a glass that reacts to temperature, going from transparent to translucent as the days heats up.

We can learn also from old times. Like Italian town of Siena in Italy. Its narrow streets provided shade to pedestrians. A Renaissance house with its layering of shutters keeping the warmth in and heat out. Cooling process takes three or four times more energy than heating. 

Now more and more solar residential buildings for the city Rome and solar schools for hot countries (currently being planned).
