Claim 1

IN A BUILDING HAVING USEFUL ACCOMMODATION ADAPTED TO BE HEATED SOLELY BY HEAT OF RADIATION EMANATING FROM AT LEAST ONE INCANDESCENT SOURCE, THE COMBINATION COMPRISING: MEANS FOR ADMITTING SOLAR RADIATION INTO SAID USEFUL ACCOMMODATION, HEAT STORAGE MATERIAL HAVING HEAT TRANSFER SURFACES THEREON IN THERMALLY CONDUCTIVE RELTIONSHIP WITH SAID HEAT STORAGE MATERIAL, SAID HEAT TRANSFER SURFACES CONSTITUTING A MAJOR PROPORTION OF THE INTERNAL SURFACE OF SAID USEFUL ACCOMMODATION, SAID HEAT TRANSFER SURFACES BEING EXPOSED TO RECEIVE FROM TIME TO TIME RADIATION EMANATING FROM SAID INCANDESCENT SOURCE AND TRANSMITTED THROUGH SAID USEFUL STORAGE MATERIAL AND OF RE-RADIATING THE STORED CAPABLE OF REFLECTING A PROPORTION OF THE RADIATION SO RECEIVED BACK INTO SAID USEFUL ACCOMMODATION, OF ABSORBING THE REMAINDER OF THE RADIATION TO RECEIVE AS HEAT AND PASSING SUCH HEAT INTO STORAGE IN SAID HEAT STORAGE MATERIAL AND OF RE-RADIATING THE STORED HEAT INTO SAID USEFUL ACCOMMODATION TO MAINTAIN A FLUX OF WARMING RADIATION THROUGHOUT SAID USEFUL ACCOMMODATION, AND A LAYER OF HEAT INSULATING MATERIAL INCORPORATED IN SAID BUILDING AND SUBSTANTIALLY ENVELOPING BOTH SAID USEFUL ACCOMMODATION AND SAID HEAT STORAGE MATERIAL TO MINIMIZE LOSS THEREFROM, THE HEAT STORAGE CAPACITY OF SAID HEAT STORAGE MATERIAL AND THE U VALUE OF SAID HEAT INSULATING LAYER BEING CHOSEN IN RELATION TO ONE ANOTHER SO THAT, IN NORMAL USE OF THE BUILDING, RADIATION RECEIVED BY SAID HEAT TRANSFER SURFACES AND PASSED AS HEAT INTO STORAGE IN SAID HEAT STORAGE MATERIAL IS SUFFICIENT TO MAINTAIN SAID USEFUL ACCOMMODATION AT A HABITABLE TEMPERATURE DURING INTERVALS OF TIME WHEN THE RATE OF SAID RECEIPT OF ENERGY OF RADIATION BY SAID HEAT TRANSFER SURFACES IS LESS THAN THE RATE OF HEAT LOSS FROM SAID USEFUL ACCOMMDATION.
