5 A growing Economy g Number of Jobs in Tübingen +12% g Number of Inhabitants + 8%

6 The Limits to Growth in Tübingen n Medieval Center n Located between hills n Bordering the State s first Natural Reserve Park n Protected Nature all around the City n Nearly no green field development since 1995

7 Goals of the Tübingen development concept n Renewal and improvement of the underdeveloped parts of the city n Brown field development instead of Green field development n Urban neighbourhoods instead of monofunctional residential areas n Protecting the Borders Zero Sprawl

8 Military Area 1991 beginning of Conversion

9 Französisches Viertel 2008

10 Military Area 1921

11 Loretto-Areal 2008 after Conversion

12 Industrial Area 1921

13 Mühlenviertel 2011 after Conversion

14 Under Construction Two industrial Sites Closed Freight Rail Station Alte Weberei Güterbahnhof Sidler

15 The Tübingen Development Concept: Renewing the essential Elements of the European City

16 1. Small-scale mixed use development

17 2. High urban density + integration of old buildings

18 3. Public space creating the living-room of the neighbourhoods

19 4. Division of plots + Variety of actors

20 5. Advanced Energy Supply: Example Alte Weberei n District Heating System (compulsory) n New Process in Purification Plant n Use of Biogas in Combined Cycle Power Plant n 95% Carbon neutral District heating system

21 Respecting the Limits to Growth Tübingen s Public Campaign to reduce CO2 Emissions Tübingen goes blue Target: -40% within 15 Years (Base 2006)

22 1. Buildings. From Old School to New School: -60% CO2- Emissions

23 The medieval Town Hall: Retrofitting and Preserving -55% CO2-Emissions

24 Consumption reduction at heating centers Systematical approach to reduce cost and energy consumption using new technology such as High efficiency pumps Connection to the district heating system Waste water heat recycling minichp (small size cogeneration) Heat exchanger for the sewer

25 Heat consumption measurable success (adjusted) heat consumption of municipal buildings [MWh/a] Reduction of heat consumption (seasonal adjusted) of municipal buildings up to almost 25 %, despite increasing quantity and usage of buildings. e.g. by: municipal energy-management, energy saving programme, redevelopments.

26 Raising public Awareness The alternative Ice Bucket Challenge

27 2. Electricity: Renewables taking over 50% green electricity target Target - Wind power realized Solar power realized Hydro power realized

28 New school: PV-plant built an owned by parents

29 Solar power: photovoltaic systems

30 PV installation measurable success Photovoltaik-Power [kwpeak] in January of the year The installed PV-power has increased tenfold since january Solar systems are installed by the public utility itself. Households get a financial support from the public utility for installing solar systems.

31 Hydroelectric power station

32 How to involve citizens Bring your old get one free

33 Smart technology: Heat circulation pumps A high efficient heat pump saves 2000 Euro n Exchange of over 300 pumps in kommunal buildings n Public utilities exchanged about 250 pumps in private houses, financed by a innovative minicontractingprogram

34 Power consumption a measurable success Power consumption [kwh per capita] Reduction of power consumption per capita up to 10%

35 Energiewende in Tübingen 5 MW electric boiler delivers flexibility

36 Cogeneration: combined heat and electricity

37 district heating networks in Tübingen

38 3. Going Green: Public Transportation and Bikes

39 Public transportation a measurable success n 35 bus lines serve 376 bus stations n A total route system of 343 kilometer n Dense time device n Close coordination between city planning and local city transport 20,5 20,0 19,5 19,0 18,5 18,0 17,5 17,0 16,5 16,0 Number of passengers (Mio.)

40 Car sharing instead of car owning One shared car substitutes 4 to 8 private cars. Shared cars are more up-to-date and more eco-friendly than private cars. n The city council has replaced company cars for car sharing membership. n exclusive urban spaces for shared cars n Car sharing tasting offers and campaigns

41 CarSharing a measurable success Number of carsharing members in January of the year The number of members using carsharing has increased by almost 180%. Tübingen ranks second among German cities in carsharing usage per capita.

42 Make Cycling popular Expansion and improvement of bike path connections (bicycle lane; modification; new construction) Development of parking facilities for bicycles 7,00 6,00 Arrangements to improve the bicycle -atmosphere (to go to work by bicycle; bicycle competitions for schools and companies; Stadtradeln ; consulting) Tenfold increase of the budget for bicycle traffic per year and inhabitant 5,00 4,00 3,00 2,00 1,00 0, EW EW EW EW EW EW EW EW EW EW

43 Bicycle Lane - example Mühlstraße After: Upgrading Freedom of choice Speed reduction Before

44 Safer Cycling Promotion

45 Electrically assisted bicycles n Municipality uses bicycles and electric bicycles n Big events with the possibility to test run electric bicycles, organised with local bicycle dealers n 100 Euro grant for the purchase of any electric bicycle if combined with a one-year commitment to green electricity.

46 Internal mobility management n The employment of a consultant for mobility management occured n An interplant forum for Internal mobility management is established n Agreed activities: n collective commuting n internal promotion of bicycle traffic n employee information

47 Environmentally friendly mobility 100 pedestrians 75 bicycles 50 busses, trains 25 cars 0 local traffic source and target traffic total traffic

48 CO 2 - a measurable success: -18% per capita energy- induced CO2 emissions [t/per capita] * Be Be Be Be Be Be Be EW EW EW EW EW EW EW Whg Whg Whg Whg Whg Whg Whg. power (without KWK) heat (with KWK) traffic

49 Tübingen s Smart and Green Growth n Zero Use of unspoilt Land n Employment +12% n Population +10% n Local Tax Revenues +200% n CO2-Emissions -18% n Green Electricity 50%
