BUILDING ENVELOPE SURFACE ELEMENT WITH CONTROLLABLE SHADING
The invention is directed to a building envelope surface element with controllable shading. The object of finding a novel possibility for controllable shading of building envelope surface elements which permits a control without electric area electrodes and has short switching times is met according to the invention in that the fluid flows through capillary channels via a fluid circuit so as to be circulated by means of a pump, in that magnetic particles are incorporated in the fluid in the form of a suspension, and in that at least one particle collector is arranged to be controllable outside of the capillary channels in order to concentrate the magnetic particles incorporated in the fluid in defined pipe portions of the particle collector by magnetic attraction and to decouple the magnetic particles transiently from the fluid circuit.
