1 Energy Efficient Cities Initiative Practitioners Roundtable Discussion Stockholm City Malin Olsson, Stockholm City Planning Administration

3 The City of Stockholm inhabitants (Stockholm Region 1.95 millions) 14 city districts dwellings (ca 10 % in one-family houses) 1.86 person / dwelling 30 km x 20 km 188 km persons / km 2 40% green areas

4 Vision 2030 MULTIFACETED & FILLED WITH EXPERIENCES INNOVATIVE & GROWING THE STOCKHOLM OF CITIZENS inhabitants year 2030

5 City Strategy - build the city inwards reuse of already developed land preserve and develop the character develop semi-central areas develop suburbs good access - public transportation existing structures - local demands

7 Hammarby Sjöstad largest urban development project in Stockholm 160 hectare new apartments and m 2 new office space, retail, services etc. infrastructure projects construction period billions SEK ($ 2,8 billions) the city invests 20 % today, about 2/3s completed

10 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

11 The Hammarby Model Energy Waste Water and sewage

12 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.

13 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 treated locally/settled and then drained into Hammarby Sjö - not to the wastewater treatment plant.

14 Waste An underground automated waste disposal system reduces the transports 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.

15 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.)

16 Environmental Index Transports of Indiviuals in Hammarby Sjöstad The extraction of non renewable energy sources has decreased with approx. 51 %* The emissions to air, land and water for the transports of individuals, have decreased with approx. 67 %, a result of improved public transports with the light rail * 1,2 1,0 0,8 0,6 0,4 Mode of Conveyance Reference No ferry and "Tvärbana" Today Hammarby Sjöstad light rail Car 35% 21% "Tvärbanan" Light rail 0% 34% Bus 50% 18% Bicycle 7% 9% Walk 8% 18% Extraction of non renewable energy sources 1,2 1,0 0,8 0,6 0,4 Emissions to air, land and water * Includes transports by car 0,2 0,0 Reference Hammarby Sjöstad 0,2 0,0 Referens Hammarby Sjöstad (Source: Grontmij)

17 Conclusions integrated planning municipal involvement clear vision and strategy organisation/ co-operation

18 Next step? 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
