Project Or by Christoph Klemmt

Architect Christoph Klemmt has created Project Or, a vortex-shaped installation in a courtyard in Milan that reacts to sunlight. The installation is made up of photo-reactive segments that are translucent when in the shade but coloured when exposed to sunlight. he polygonal segments of the surface react to ultra-violet light, mapping the position and intensity of solar rays. When in the shade, the segments of OR are translucent white. However, when hit by sunlight they become coloured, flooding the space below with different hues of light. At night, OR transforms into an enormous ‘chandelier’, disseminating light into the surrounding courtyard, an atmospheric space for events and gatherings. The hues generated by the photoreactive surface are therefore indicators of changes in weather and daylight, a dynamic architectural tool that can be used on building exteriors. OR is skin, OR is shining, OR is the light OR the shade. OR is the first time that photoreactive technology has been used on an architectural scale. The ecological structure is a step in exploring the possibilities of photoreactive materials in the fields of furniture and design. The beauty of OR is its constant interaction with the elements. Each moment of the day is unique.
