GreenPix is a groundbreaking project applying sustainable and digital media technology to the curtain wall of Xicui entertainment complex in Beijing, near the site of the 2008 Olympic Games. Featuring the largest color LED display worldwide (back in 2008) and the first photovoltaic system integrated into a glass curtain wall in China, the building performs as a self-sufficient organic system, harvesting solar energy by day and using it to illuminate the screen after dark, mirroring a day’s climatic cycle.
The Media Wall provided the city of Beijing with its first venue dedicated to digital media art, while offered the most radical example of sustainable technology applied to an entire building’s envelope to date. The building opened to the public on June 24, 2008, with a specially commissioned program of video installations and live performances by artists from China, Europe and the US.
The display requires zero external energy, as the facade harvests solar energy by day & uses it to illuminate the screen after dark. the display comprises of 2,292 color (RGB) LED’s light points comparable to a 24,000 sq. ft. (2.200 m2) monitor screen for dynamic content display.The polycrystalline photovoltaic cells are laminated within the glass of the curtain wall & placed with changing density on the entire building’s skin. the density pattern increases building’s performance, allowing natural light when required by interior program, while reducing heat gain & transforming excessive solar radiation into energy for the media wall.
You can play with the online simulator.
