Environmentally heated and cooled building

In combination a solar heated building comprising:

• a collector means carried in the attic of said building for absorbing solar energy and heating the air within said attic,
• a thermal storage chamber carried below the bottom floor of said building,
• said thermal storage chamber including a rock bed extending substantially under the entire area of said floor,
• a lower plenum positioned substantially in the middle of said rock bed extending transverse thereof,
• air flow passages provided in opposite walls of said lower plenum extending into said rock bed,
• duct means connected between said attic and said plenum through which conditioned air passes between said attic and said storage chamber,
• a fan connected to said duct means for circulating air therethrough,
• registers carried in said floor and connected to said duct means for supplying conditioned air to said building,
• said duct means including an outside air arm communicating with the air outside said building,
• power operated damper means provided in said duct means for selectively controlling the path that said air flows through said storage chamber, said building, said attic and through said outside air arm,
• said thermal storage chamber having an inlet and outlet through which air flows,
• first and second sensors positioned adjacent said inlet and said outlet of said thermal storage chamber generating signals indicating the temperature at said locations,
• additional sensors located to generate signals indicating the temperature of the outside air, the temperature of the air in said attic and the temperature of the air in said building, and
• control means connected to said sensors for activating said power operated damper means for controlling the air flow path through said building, storage chamber and said attic responsive to predetermined conditions.
