ABSTRACT:
Energy efficient houses are built with concrete outer walls underground in thermal contact with the earth temperature, which is at a comfortable level for human use and varies little from summer to winter. Thus, the inner concrete walls are made active energy transfer surfaces of a year around temperature control system, which in its simplest form comprises a fan circulating interior building air in a thermal exchange relationship over substantially the entire concrete inner wall surface. For even better thermal efficiency, the outer concrete walls are thermally insulated on the upper portions nearer the earth's surface, where a larger variation of temperature is encountered from summer to winter. Therefore the entire inner concrete wall thermal exchange surface may be kept typically at a temperature of 77 degrees F plus or minus 2 degrees throughout the year and thus constitute a most efficient primary source of thermal energy.
