While attending a RESIN project meeting in Freiburg, my colleagues and I got a guided tour of the noted sustainable urban district of Vauban. The designers have created a very liveable, vibrant, and dense neighbourhood by moving automobiles to the periphery and providing a wide range of services. The area attracts some 25,000 visitors per year from around the world who are interested in understanding how sustainability principles have been realised on the ground.Definitely worth a visit!
