CNN: Building a green oasis in the heart of a city
By Kieron Monks, CNN
(CNN) – The Bahnstadt campus in Heidelberg, south-west Germany, is one of the largest and most ambitious urban developments in Germany. Two billion euros have been invested in converting a freight train terminal into a cutting-edge eco community. The 116-hectare campus is entirely powered by renewable energy, which is regulated by smart metering. Every one of the 2,000 homes is a „passive house“ that efficiently retains energy and does not need a heating system.
The Bahnstadt experiment is now going a step further with the arrival of Heidelberg Village from Frey Architects, a 162-apartment block covered with green facades and rooftop gardens, which opens in early 2017.
The development is expected to offer significant environmental benefits, but the architects have a more ambitious vision of sustainability.
