OR2 is a combination shading device and solar-powered chandelier designed by London-based Orproject. The structure’s purpose is twofold: it acts as a source of shade during the day, and it turns into a dazzling chandelier at night, dispersing light collected by photovoltaic cells hours before.
The pink-tinted structure was built as part of the London Festival of Architecture in June 2010. The work is a follow-up project to the OR single-surface solar roof structure. OR2 is translucent while in the shade, but it quickly fills in with color when exposed to sunlight.
According to the designers, OR and OR2 are the first structures to use photo-reactive technology at an architectural scale. The designers explain, “The beauty of OR2 is its constant interaction with the elements, at each moment of the day OR’s appearance is unique.”
Orproject is a London based architecture and design practice set up in 2006 by Francesco Brenta, Christoph Klemmt and Laura Micalizzi. Their 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. Past projects range from experimental small scale installations to large real estate developments.
