Greenpix Media Wall, Beijing, China

Issue 44 Aug / Sep 2008 : Architectural : Facade

Lighting Design: ARUP LIGHTING Architect: SIMONE GIOSTRA & PARTNERS


Simone Giostra & Partners Archietcts has designed the Greenpix Zero Energy Media Wall - a groundbreaking project applying sustainable and digital media technology to the Xicui Entertainment Complex in Beijing, near the site of the Olympics.

Featuring the largest colour LED display worldwide and the first photovoltaic system integrated into a glass curtain wall in China, GreenPix transforms the building envelop into 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.

Arup provided lighting design and façade engineering for the project.
“The Media Wall will provide the city of Beijing with its first venue dedicated to digital media art, while offering the most radical example of photovoltaic technology applied to an entire building’s envelope to date,” said Simone Giostra, architect for the project. The building opened to the public on June 24, with a program of video files by Aaajiao (Xu Wenkai) and Shih Chieh Huang, organised by Defne Ayas, a Shanghai based new media and performance curator for New York’s Performa biennial, and a new video piece by the Russian Beijing-based artist Varvara Shavrova.

Greenpix behaves like an organic system, absorbing solar energy during the day and then generating light from the same power that evening. The project promotes the uncompromised integration of sustainable technology in new Chinese architecture, responding to the aggressive and unregulated economic development currently undertaken by the industry, often at the expense of the environment.

With the support of leading German manufacturers Schueco and SunWays, Giostra and Arup developed a new technology for laminating photovoltaic cells in a glass curtain wall and oversaw the production of the first glass solar panels by Chinese manufacturer SunTech. The polycrystalline photovoltaic cells are laminated within the glass of the curtain wall and placed with changing density on the entire building’s skin. The density pattern increases the building’s performance, allowing natural light when required by interior program, while reducing heat gain and transforming excessive solar radiation into energy for the media wall.

GreenPix is a large-scale display comprising 2,292 Thorn RGB LED light points comparable to a 24,000sqft (2.200sqm) monitor screen for dynamic content display. The very large scale and the characteristic low resolution of the screen enhances the abstract visual qualities of the medium, providing an art-specific communication form in contrast to commercial applications of high resolution screens in conventional media façades.

Xicui’s opaque box-like commercial building gains the ability of communicating with its urban environs through a new kind of digital transparency. Its ‘intelligent skin’ interacts with the building interiors and the outer public spaces using embedded, custom-designed software, transforming the building façade into a responsive environment for entertainment and public engagement.

The full integration of media/information technology with architecture in an urban context represents a new kind of communication surface devoted to unprecedented forms of art, while projecting information about the behaviour and activity of the building to a wide range of distances and engaging a vast audience within the city of Beijing. The innovative use of technology and experimental approach to communication and social interaction defines new standards in the context of urban interventions worldwide, raising global interest in the integration of digital technology with architecture and reinforcing the reputation of Beijing as a centre for innovation and urban renewal.

GreenPix results from the ambitious collaborative talent of architects, engineers, programmers, artists and curators. The unprecedented immense scale of the display and intensity of the light will allow a generation of young artists, both local and international, to create site specific and socially relevant projects.

The new-generation showcase is a highly visible venue, both within the Beijing metropolis and internationally, and a powerful platform to display the work of emerging artists. Its high visibility will be conducive to interactive projects and artistic dialogue within and beyond China’s borders. A compelling program of videos, installations and performances will be organised by a diverse team of independent curators, art institutions, galleries, media schools, corporations, collectors and benefactors, all lead by curator and producer Luisa Gui.
