Seeking an eco-friendly update to musty old libraries and sterile offices, Greeen! Architects has unveiled the Bibliosphere, a massive sustainable structure where city and university are combined. Bearing more than a passing resemblance to an earth-bound death star, the great green globe features a number of low-impact and sustainable features including natural ventilation, sweeping views of the cityscape for natural lighting, solar protection, and the use of renewable energy sources.

Greeen! Architects designed the Bibliosphere library and office complex as a landmark and focal point for the University of Duisburg-Essen in Germany. When the Bibliosphere is complete, the architecture firm hopes to receive a gold certification from the German Sustainable Building Council thanks to its low energy consumption–the building is expected to use 50% less energy than German standards require.

Of course, less futuristic-looking library complexes have their merits too. Scottsdale, Arizona’s Arabian Library is aiming for a LEED Silver certification and features steel, granite, and recycled cotton insulation from nearby towns.
