Abstract: A device for climate control of a building (20), in which flatly formed external temperature elements (5) at least partially cover an outer side of the building (20), wherein the external temperature-control elements (5) are settable to a predefinable temperature value. Furthermore, a temperature-control element (5) and a method for climate control of a building (20) are specified.

Abstract: An optical assembly includes an intermediate image plane between a first lens unit and a second lens unit. The first lens unit may image an image from a first image plane into an enlarged real intermediate image in the intermediate image plane. A totality of possible ray paths through the first lens unit defines a first entrance region in the first image plane and a first exit region in the intermediate image plane. The second lens unit may image an image from the intermediate image plane into an enlarged real image in a second image plane. A totality of possible ray paths through the second lens unit defines a second entrance region in the intermediate image plane and a second exit region in the second image plane. The second entrance region comprises a first part of the first exit region and excludes a second part of the first exit region.
