ABSTRACT OF THE INVENTION Low energy demand structure with side walls, roof, and foun- dation is disclosed wherein the side walls have inner and outer structures, the outer structure of frame construction with very heavy insulation substantially filling the outer structure. The inner surface of the outer wall structure is provided with a panel cover to hold the insulation in place and over the panel a moisture impermeable seal is placed. The inner wall structure is of vertical frame construction and provides circulating air pas- sages and a finish interior surface. The ceiling is of similar structure with the circulating air passages of the ceiling and walls in communication with each other. The upper portion of the structure rests on foundation walls which extend at least 3 - 4' below the frost line and which are faced with rigid foam insula- tion also extending 3 - 4' below the frost line. A lowermost floor slab of concrete, which is usually the basement floor, has circulating air passages formed therein which are in communica- tion with the air passages of the side walls or inner basement walls which, if present, are of hollow construction with air passages therein and the inner and outer basement walls are sepa- rated by a moisture impermeable vinyl sheeting and similar sheet- ing is placed between the floor slab and the underlying earth mass. The lowermost slab is in conductive thermal contact with the earth mass which serves to maintain the temperature of the interior of the structure between 68-70° F due to the flow of thermal energy between the earth and slab and the flow from the slab by convetion to the air circulating through the passages in the slab wall and roof. Preferably, auxillary blowers are uti- lized to insure positive circulation of the heating or cooling air in the passages. Miniature heat pump units may also be uti- lized and located within the outer wall structure for coupling to the air passageways and outdoors.
