An important experiment in sustainable building has been completed in the industrial city of Linz:
The Solar City in the south of Linz was developed as a model city for the 21st century, a prime example of ecologically sound urban development. It's not just another suburban development, but a complete neighborhood including a marketplace, businesses, schools, community centers and all of the other amenities necessary for a modern city of 3000 people. It is connected to the public transportation network, and almost completely car free. The Solar City is situated next to the Danube basin and has it's own bathing lake.
As the name might imply, special attention has been given to the use of sustainable building methods, from low to zero energy technology, solar collectors and photovoltaic cells to water use and treatment, the development is a practical implementation of sustainable building practices. The architectural quality of the residential and infrastructural buildings is also impressive. Internationally known architects like Norman Foster and Richard Rogers have developed low energy buildings for the project. It's a rare example of how new technologies and ecologically friendly design can result in an improved quality of living for nearly the same cost of conventional building methods.
