Abstract: The invention is related to a solar house having an outer wall made of heat absorbing and transmitting material and an inner wall made of heat insulating material. An outer chamber is defined by the area between the outer and inner wall and an inner chamber is defined by the area within the inner wall. By closing and opening a passageway between the ambient and the outer chamber, the direction and path of a convection air current is regulated so as to produce a cooling effect in warm weather and a heating effect in cool weather.
