Low-energy building, especially self-sufficient zero-energy house

Abstract

The invention relates to a system which can be used to air-condition buildings and other useable areas used by humans, in a completely self-sufficient manner.

1 .- 104 . (canceled) 
     
     
         105 . A building with a ventilation system, comprising at least one conduit, which comprises a first pipe arranged in a second pipe so that supply and exhaust air can be guided through said conduit according to the counterflow principle, wherein said conduit is arranged in a first zone underneath the building and in a second zone in the ground adjacent to the building. 
     
     
         106 . The building as claimed in  claim 105 , wherein 30 to 70% of the length of said conduit is arranged in the first zone. 
     
     
         107 . The building as claimed in  claim 105 , wherein 30 to 70% of the length of the conduit is arranged in the second zone. 
     
     
         108 . The building as claimed in  claim 105 , comprising walls or a roof having a core zone formed as a temperature barrier through which fluid conduits extend through which a heat exchange with the first or second zone can take place. 
     
     
         109 . The building as claimed in  claim 105 , comprising fluid conduits for supply of fresh air, wherein at least sections of said fluid conduits for fresh air supply extend through an underground heat storage. 
     
     
         110 . The building as claimed in  claim 105 , comprising walls or a roof having a core zone formed as a temperature barrier through which fluid conduits extend, wherein said fluid conduits are connected to a heat pump. 
     
     
         111 . A building, comprising walls or a roof having a core zone formed as a temperature barrier through which fluid conduits extend, wherein individual segments of said fluid conduits are associated to individual rooms of the building. 
     
     
         112 . A building as claimed in  claim 111 , wherein the building is connected to a underground heat storage which comprises fluid conduits arranged in the ground, wherein substances for improving the heat transfer are added to the ground adjoining said fluid conduits. 
     
     
         113 . A building as claimed in  claim 112 , wherein the substances for improving the heat transfer comprise hydrophilic chemicals, water-retaining materials, metal chips or salts. 
     
     
         114 . A landing strip for aircraft, comprising fluid conduits arranged underneath said landing strip, said fluid conduits being connected to an underground heat storage that is provided underneath said maneuvering area.
