Patent ID: 8151788

Claim:
Wall or roof of a building, wherein at least one heat controlling element ( 1 ) for controlling a temperature in the building is arranged in the wall (W) or the roof to form a segment of the wall (W) or roof, the heat controlling element ( 1 ) comprising at least a first section ( 3 ) and a second section ( 4 ), the first section ( 3 ) comprising a heat collecting and storing material and the second section ( 4 ) comprising a heat insulating material, wherein the heat controlling element ( 1 ) may adopt a first configuration, in which the first section ( 3 ) is directed towards the outside of the building and the second section ( 4 ) is directed towards the inside of the building, and a second configuration, in which the second section ( 4 ) is directed towards the outside of the building and the first section ( 3 ) is directed towards the inside of the building, characterized in that the heat collecting and storing material of the heat controlling element ( 1 ) may be connected to a metal reinforcement of the building structure ( 15 ) by at least one connecting element ( 16 a , 16 b ) so that there is direct thermal contact between the heat collecting and storing material of the heat controlling element ( 1 ) and the metal reinforcement of the building, wherein the connecting element ( 16 a , 16 b ) is adjustable between a contacting position for providing direct thermal contact between the heat collecting and storing material of the heat controlling element ( 1 ) and the metal reinforcement of the building structure ( 15 ) and an interrupting position for interrupting direct thermal contact between the heat controlling and storing material of the heat controlling element ( 1 ) and the metal reinforcement of the building structure ( 15 ).
