The diagram above illustrates the principle of solar heating for houses.  The extending eaves
(overhang) which will shade a south wall in summer will not shade it in winter, because the
position of the sun is different then.  Double glass walls provide effective insulation,

The model below shows a small house designed for modern living. The use of identical
flooring indoors and out, the abundance of glass, and the many openings help to integrate
the house with its surroundings. Courtesy Cranbrook Academy of Art.
