Abstract
Abstract Low grade heat is supplied to heat air which is used to provide an insulating sheath for a building or the like. The low grade heat is obtained from the ground below the hard frost line from either air or water, or from solar collectors, biomass or any other suitable source of such heat, and is used to heat air which is then circulated in a space within the walls of the building, thereby maintaining the internal temperature within the walls at approximately 45°-65° F. The air insulating sheath so provided reduces the driving force which takes heat out of the building in winter and which permits heat entry in summer. The energy required to bring the internal building temperature to a comfortable degree in winter or summer is thereby drastically reduced, as is the cost associated therewith.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
216 words
The method of insulating a building structure comprising: (a) obtaining low grade heat from air or water below the hard frost line at the location of said building, said low grade heat being in the temperature range of approximately 45°-65° F., (b) heating or cooling air to the temperature range of approximately 45°-65° F. by heat exchange with said low grade heat in a first heat exchange wherein a liquid that has been circulated below the frost line to collect said low grade heat is delivered to a first heat exchanger to provide a first source of heating or cooling to the air circulating within said heat exchanger, and a second heat exchange wherein sid low grade heat is transferred to ambient air that is circulated through a second heat exchanger and said ambient air is then delivered by conduit means to said first heat exchanger, thereby providing a second source of said low grade heat to the air within said first heat exchanger, and (c) circulating said heated or cooled air below and adjacent the floor of said building, above and adjacent the ceiling of said building, and within said channels in the walls of said building, thereby providing an insulating sheath of air substantially surrounding but not entering the useable space within said building.
Claim 2
Independent Claim
216 words
The method of insulating a building structure comprising: (a) obtaining low grade heat from air or water below the hard frost line at the location of said building, said low grade heat being in the temperature range of approximately 45°-65° F., (b) heating or cooling air to the temperature range of approximately 45°-65° F. by heat exchange with said low grade heat in a first heat exchange wherein a liquid that has been circulated below the frost line to collect said low grade heat is delivered to a first heat exchanger to provide a first source of heating or cooling to the air circulating within said heat exchanger, and a second heat exchange wherein sid low grade heat is transferred to ambient air that is circulated through a second heat exchanger and said ambient air is then delivered by conduit means to said first heat exchanger, thereby providing a second source of said low grade heat to the air within said first heat exchanger, and (c) circulating said heated or cooled air below and adjacent the floor of said building, above and adjacent the ceiling of said building, and within said channels in the walls of said building, thereby providing an insulating sheath of air substantially surrounding but not entering the useable space within said building.
Claim 3
Dependent Claim
242 words
A combination building structure and air circulation means comprising a foundation supporting a building having a floor, sidewalls having air channels therein, a ceiling and a roof, and means for obtaining low grade heat from air or water below the hard frost line at the location of said building, said low grade heat being in the temperature range of approximately 45°-65° F., and means for heating or cooling air to the temperature range of approximately 45°-65° F. by heat exchange with said low grade heat in a first heat exchange wherein a liquid that has been circulated below the frost line to collect said low grade heat is delivered to a first heat exchanger to provide a first source of heating or cooling to the air circulating within said heat exchanger, and a second heat exchange wherein said low grade heat is transferred to ambient air that is circulated through a second heat exchanger and said ambient air is then delivered by conduit means to said first heat exchanger, thereby providing a second source of said low grade heat to the air within said first heat exchanger, and circulating said heated or cooled air in the temperature range of approximately 45°-65° F. to the space below and adjacent said floor, the space above and adjacent said ceiling, and within said channels in said walls, thereby providing an insulating sheath of air substantially surrounding but not entering the useable space within said building.
Claim 4
Dependent Claim
