Abstract: A solar heated building structure comprising an exterior shell including side walls and a roof section with the major portion of the roof section comprised of light transmitting panels or panes of material to permit passage of sunlight into the attic section of the building structure. The structure is provided with a central vertical hollow support column containing liquid storage tanks for the circulation and collection of heated water from a flexible conduit system located on the floor of the attic compartment. The central column serves as a heating core for the structure and communicates by way of air conduits or ducts with the living areas of the structure. Fan means are provided for continuously or intermittently circulating air over the hot water storage tanks in the core to transfer heat therefrom and distribute the heated air into the living areas.

Abstract: A solar-heated building structure comprising an exterior shell including a generally semi-spherical roof section comprising a plurality of light-transmitting panes of material providing a air and water-tight exterior surface therefor, horizontal floor means dividing the shell into a heat-insulated living compartment, and an attic compartment extending between the living compartment and the roof section to form a solar heat collector. Air in the attic compartment is heated by absorbed energy from sunlight passing through the light-transmitting panes of the roof section. Means are provided for circulating air into and out of the attic compartment to heat the same, and for circulating the thus heated air through the living compartment to maintain the living compartment at a desired temperature. Means are also provided in the shell for storing heat energy from the heated air for use to heat the living compartment when sunlight energy is unavailable.
