19 The Environmental Programme twice as good land use technical infrastructure; - energy supply, - water and sewage management - waste management building materials public transportation, parking etc user participation

20 The Hammarby Model Energy Waste Water and sewage

21 Energy Combustible waste is converted into district heating and electricity. The heat from the treated wastewater is converted into district heating and cooling. Solar energy is converted into electrical energy or used to heat water.

22 Water & Sewage A pilot sewage treatment plant facility has been built to evaluate new sewage treatment techniques. Biogas is extracted from the digestion of sewage sludge. Rainwater from streets is filtered locally, settled and then drained into lake Hammarby - not into the wastewater treatment plant.

23 Waste An underground automated waste disposal system reduces the transport in the area and makes it easy to sort the waste. As does a block based system of recycling rooms and area-based environmental stations. All recyclable material Is recycled: newspapers, glass, cardboard, metals, etc.

24 Environmental Load Profile (ELP) The major reduction of environmental load stems from the buildings, real estate and the city district Referens District Operation District Production Real Estate Operation Real Estate Production Building Dismantling Building Operation Building Construction Photochemical Ozone Creation (g C 2 H 4 eq.)

25 Twice as good - reduce environmental impact by half compared to the contemporary level for newly constructed housing Result: 30 40%

26 Conclusions integrated planning land management clear vision and strategy organisation/ co-operation

27 Next phase Evaluation of the environmental programme of Hammarby Sjöstad Implementation in Stockholm s next large urban development New and improved environmental programme Improvement of the Environmental Load Profile Focusing on energy efficiency and reduction of greenhouse gas emissions
