Or2 is a single surface roof structure which reacts to sunlight. The 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 Or2 are translucent white. However when hit by sunlight they become coloured, flooding the space below with different hues of light. During the day Or2 becomes a shading device passively controlling the space below it. At night Or2 transforms into an enormous chandelier, disseminating light which has been collected by integrated photovoltaic cells during the day.

Orproject is an architecture and design practice set up in 2006 by Francesco Brenta, Christoph Klemmt, Laura Micalizzi and Rajat Sodhi. Our work explores advanced geometries with an ecologic agenda, the integration of natural elements into the design results in an eco-narrative unfolding into the three dimensional space. Our projects range from experimental small scale installations to large real estate developments. We produce high end luxury design, covering all aspects of a project from design and planning to practical completion. Our work has been published and exhibited widely, amongst others for the Furniture Fair in Milan, at Palais de Tokyo in Paris and at the National Museum of China in Beijing.
