A double-walled structure utilizes air as the heat transfer medium between solar-heated outer walls and either the interior space or heat storage means beneath the structure. A load-bearing layer of gravel supporting the floor and subterranean gravel pits form the heat storage means. In summer, during the day, solar-heated air gives up heat to the storage means; at night, heat is radiated to the atmosphere and thus-cooled air is used for daytime cooling by storage either in the gravel pits or the gravel layer supporting the building floor. In winter, air is heated in the storage means for interior circulation and, when available during daylight hours, solar-heated air may be used directly or temporarily stored for nightime use. Cold can also be stored during winter months in separate storage means for additional summer cooling capacity.

A building structure comprising: exterior walls and roof structure including spaced inner and outer walls and means for circulating air therebetween; first heat storage means comprising subterranean pits filled with gravel, air spaces between said gravel forming an air passage therethrough, said first heat storage means being located beneath or adjacent said building structure; second heat storage means comprising a load-bearing layer of gravel supporting the floor of said building structure, air spaces between said gravel forming an air passage therethrough; means for circulating air through said first and second heat storage means; conduit means connecting said respective circulating means and the interior space of said building structure; and control means governing air flow through said conduits, heat storage means and between said inner and outer walls. A building structure comprising: exterior walls and roof structure including spaced inner and outer walls; heat storeage means comprising subterranean trenches filled with gravel sized to provide air spaces between said gravel and forming horizontal air passages therethrough, said gravel having an average particle diameter in the range of ⅜ to 2 inches, said heat storage means being in heat-exchange relation with the ground and located beneath or adjacent said building structure; means for circulating air between said walls and through said heat storage means; conduit means connecting said circulating means and the interior space of said building structure; and control means governing air flow through said conduits, heat storage means and between said inner and outer walls.
