1. In combination with a concrete slab laid above an earthen surface to form the floor of a building above it, said building including a roof and a peripheral sidewall, said slab having a top surface, a bottom surface, an inlet port and an outlet port through said slab from surface to surface spaced
1. In combination with a concrete slab laid above an earthen surface to form the floor of a building above it, said building including a roof and a peripheral sidewall, said slab having a top surface, a bottom surface, an inlet port and an outlet port through said slab from surface to surface spaced apart from one another;a conditioning system for the air inside the building comprising: between said earthen surface and said bottom surface a body of gravel having an inlet edge and an outlet edge, said edges being separated from one another, said inlet edge being in fluid communication with said inlet port, and said outlet edge being in fluid communication with said outlet port, whereby a fluid path exists from said inlet port through said gravel body to said outlet port;an air blower discharging air under pressure into said inlet port;a filter receiving air from said outlet port and filtering said air which it discharges into said building;said gravel body being in thermal contact with said earthen surface; anda liner of thermally conductive and gas impermeable material between and in contact with said earthen surface and said gravel body, and between and in contact with said bottom surface and said gravel body, said liner enclosing said gravel to isolate it from said earthen surface and from said slab;an air regulator in said building receiving air from said outlet part and discharging it into said building, said filter being disposed in said register;an aperture formed through the sidewall of the building in fluid communication with said air register, a first set of lowers adapted to enable and to prevent flow of air into the building, a second set of louvers being formed in said aperture to divert air to the outside of the building, and apparatus to adjust the setting of said second louvers. 2. Apparatus according to claim 1 in which said edges adjoin said fluid path said liner isolating said path from said earthen surface. 3. In combination with a concrete slab laid above an earthen surface to form the floor of a building above it, said building including a roof and a peripheral sidewall, said slab having a top surface, a bottom surface, an inlet port and an outlet port through said slab from surface to surface spaced apart from one another;a conditioning system for the air inside the building comprising: between said earthen surface and said bottom surface a body of gravel having an inlet edge and an outlet edge, said edges being separated from one another, said inlet edge being in fluid communication with said inlet port, and said outlet edge being in fluid communication with said outlet port, whereby a fluid path exists from said inlet port through said gravel body to said outlet port;an air blower discharging air under pressure into said inlet port;a filter receiving air from said outlet port and filtering said air which it discharges into said building;said gravel body being in thermal contact with said earthen surface; anda liner of thermally conductive and gas impermeable material between and in contact with said earthen surface and said gravel body, and between and in contact with said bottom surface and said gravel body, said liner enclosing said gravel to isolate it from said earthen surface and from said slab,an air regulator in said building receiving air from said outlet port and discharging it into said building, said filter being disposed in said register;an aperture formed through the sidewall of the building in fluid communication with said air register, a first set of lowers adapted to enable and to prevent flow of air into the building, a second set of louvers being formed in said aperture to divert air to the outside of the building, and apparatus to adjust the setting of said second louvers,the said inlet edge of said gravel body being adjoined by a plenum extending from said inlet port, and a second plenum adjoining said outlet edge leading to said outlet port, said plenums being lined by said liner t o separate them from the earthen surface. 4. In combination with a concrete slab laid above an earthen surface to form the floor of a building above it, said building including a roof and a peripheral sidewall, said slab having a top surface, a bottom surface, an inlet port and an outlet port through said slab from surface to surface spaced apart from one another;a conditioning system for the air inside the building comprising: between said earthen surface and said bottom surface a body of gravel having an inlet edge and an outlet edge, said edges being separated from one another, said inlet edge being in fluid communication with said inlet port, and said outlet edge being in fluid communication with said outlet port, whereby a fluid path exists from said inlet port through said gravel body to said outlet port;an air blower discharging air under pressure into said inlet port;a filter receiving air from said outlet port and filtering said air which it discharges into said building;said gravel body being in thermal contact with said earthen surface; anda liner of thermally conductive and gas impermeable material between and in contact with said earthen surface and said caravel body, and between and in contact with said bottom surface and said gravel body, said liner enclosing said gravel to isolate it from said earthen surface and from said slab,an air regulator in said building receiving air from said outlet port and discharging it into said building, said filter being disposed in said register;an aperture formed through the sidewall of the building in fluid communication with said air register, a first set of lowers adapted to enable and to prevent flow of air into the building, a second set of louvers being formed in said aperture to divert air to the outside of the building, and apparatus to adjust the setting of said second louvers;a pair of said gravel bodies and outlet ports being provided, with a common plenum between them; andsaid inlet edge of said gravel body being adjoined by a plenum extending from said inlet port, and a second plenum adjoining said outlet edge leading to said outlet port, said plenums being lined by said liner to separate them from the earthen surface. 5. Apparatus according to claim 4 in which said edges adjoin said fluid path said liner isolating said path from said earthen surface.
