Hammarby Sjöstad, a city part of Stockholm (Sweden), used to be a run-down, old industrial area. It was transformed into a modern, urban and sustainable part with currently 17.000 people living and working there.
At the end of the 1980s, this 200ha big area was degenerated, and before its transformation into an eco-area it was originally planned to change this part of the city into an Olympic village. After the attempt to get the Olympic Games to Stockholm failed, the city council agreed to transform the area into a modern, urban, city-centre quarter.
The heart of the quarter concept is an eco-cycle model with integrated concepts concerning traffic, energy, building, water, and waste. The smart transport infrastructure causes only low CO2 emissions due to its extended cycle track network and car pools open to the public. The used electricity shall come only from renewable sources; there are solar heating systems and photovoltaics on the roofs, a district heating power plant, and approximately 1000 flats with biogas powered stoves. Waste water is used to produce biogas and for the cooling-technology of power plants. For district heating power plants and for the production of electricity, combustible waste and organic waste is used and covers 50 percent of the heat and electricity consumption.
The public investment for this major project amounts to 0.5 billion Euros. A crucial part of it is the integrated planning process. In a holistic approach all involved units focussed primarily on environmental aspects. Besides the city of Stockholm and its neighbouring municipality Nacka, the Swedish Transport Authority, the public transport enterprise of Stockholm, the water company Stockholm Vatten, the energy utility Fortum, and 29 architectural offices were involved in the planning process.
The development of vacant public green spaces is compensated through the creation of biotopes in the immediate surroundings while nature reserves with a particular value are protected from cultivation. To increase the social mixing in this city district 400 flats for students and 59 homes for old people in full-time care are developed, but currently most of the areas inhabitants are better off families. Until 2007, 5.193 new jobs were created.
