Shading and illumination system

A shading and illumination system for a room in a building, comprising:

• at least one shading device configured to shade viewing openings of the building;
• at least one illumination device configured to illuminate the room;
• at least one external sensor configured to detect at least one external parameter (Pout) acting on the room from outside;
• at least one internal sensor configured to detect
• a 3D image of the room,
• at least one position of a person present in the room in the 3D image, and
• a viewing direction of the person;
• and
• a control unit configured to actuate the at least one shading device and the at least one illumination device, wherein the at least one shading device and the at least one illumination device are actuatable by the control unit depending on the at least one external parameter detected by the at least one external sensor and the 3D image, the at least one position and the viewing direction detected by the at least one internal sensor,
• wherein the control unit is configured to determine a light parameter acting on the person based on the detected viewing direction, the detected at least one position, the detected 3D image of the room, and the detected at least one external parameter, and wherein the at least one shading device or the at least one illumination device is actuatable depending on the light parameter acting on the person.
