A system for temperature-controlling rooms with a room ceiling or a room wall on which is suspended a structure of rails which run parallel to one another and form a lower rail plane running parallel to the room ceiling and an inner rail plane running parallel to the room wall, and between which a plurality of cooling or heating elements can be inserted, is characterized in that a plurality of fixing elements of which the cooling or heating elements can be fixed with respect to the rails in a vertical or inward direction facing away from the room ceiling or room wall, respectively, and a plurality of brackets which can be fastened on the rails and which force the cooling or heating elements, in a direction away from the room ceiling or room wall, into a plane which coincides at least with the lower/inner rail plane

A building using solar energy for heating and cooling is disclosed. The building comprises a fluid channel arranged for a fluid to transfer absorbed solar heat, a solar heat storage bank to store and supply the solar heat, and a mechanism for directing and controlling the flow of the fluid throughout the building. A insulating glass style solar heat collector (IGSHC) as a building element comprises a insulating glass means; a replaceable solar heat absorber removably received in a slot in the hollow space of the insulating glass, and separates the space into two subspaces; a fluid channel is thermally connected to the solar heat absorber for heat transferring; and a mechanism for directing and controlling the flow of said fluid.

A building envelope, in particular a wall, a floor, or a roof of a building with at least two shells spaced some distance apart from one another, which encloses an intermediate space, said space being essentially empty with the exception of weight-bearing and/or construction-engineering elements or being filled at least in sections with porous, open-celled material and sealed from the interior and exterior of the building, wherein controllable sealing means are provided for sealing the intermediate space from the interior and exterior and optionally separated building envelope sections from one other.
