1 A Story about the Experience & Features of one of the World s most Sustainable Cities Freiburg in Germany The Order of Engineers and Architects The Annual Mechanical Week 2016 Beirut, September 26, 2016 Presentation by Dr. Sebastian Gehart aiforia GmbH

2 founded in 1120 population: , 164 nations students: , University founded in 1457 jobs: 85,5% in service sector 1,4 million overnight guests per year max. alt.: 1,295 m Surface area: 155 km², of which 43% forest (FSC certified) sunny spot: sunshine hours p.a. Freiburg facts and figures

3 History of the Green City According to Energie-Cites (1999), The most committed leaders [of the anti-nuclear movement] joined the political arena, the administration, the utilities, found a job in educational or research activities or founded green-spirited companies. Freiburg s mayor and one-fourth of the city council are Green Party members.

4 Think global Act local 2013 Municipal Climate Protection (federal contest winner) 2012 Germany s Most Sustainable City 2012 Climate Neutral Community - State of Baden-Württemberg 2011 Most Bike Friendly City - State of Baden-Württemberg 2010 German Climate Protection Capital - Deutsche Umwelthilfe (DUH) The European City of the Year - The Academy of Urbanism, London Weltkindertag an der Ökostation Freiburg Picture from:

5 The Local Roadmap for Climate Protection Climate Protection Plan adopted in 1996 revised in 2007 & 2014 two-year municipal climate balances CO 2 2,1 m t/a - 20,7% (- 29% per capita) - 50% carbon neutral transport energy

6 Sustainability: Guiding Principle

7 Moving forward step-by-step 1. Land Conservation, Energy-Efficient Buildings & Eco-Districts The development of new low energy city districts designed with sustainability in mind, connected to integrated transport plans and with buildings designed to reduce energy demand. 2. Transport Extending and improving an integrated transport system, linking nonmotorised mobility (walking and cycling) to public transport options (bus, tram, train), with incentives and disincentives encouraging behaviour change. 3. Energy Switching to 50% co-generation for electricity and heating in the city and widespread installation of active solar energy systems on private and municipal buildings (incl. the local football stadium).

8 Freiburg s Solarstadion 2200 m² solar surface (PV) producing 275,000 kwh per year, thus avoiding the emission of approximately 136 tons of CO2 per year.

9 Nature Reserve & Sustainable Lifestyle Natural reserve Countryside reserve

10 1. Land conservation, Buildings & Eco-Districts

11 Eco Districts

12 Eco Districts: Vauban

13 Eco Districts: Vauban

14 The Roadmap to Zero- and Plus-Energy-Buildings 220 housing stock federal standard 1995 federal standard 2002 Freiburg standard 1992 Freiburg federal standard standard Freiburg passive house 2009 Freiburg passive house 2011 Average heating energy demand in kwh/m²/a (excludes water heating and electricity)

15 Municipal building stock 520 buildings (schools, administrative buildings, public amenities), total 630,000 m² All new constructions according to passive house standard Redevelopment according to Freiburg low energy standard before: 70 kwh/m²/a after: 15 kwh/m²/a

16 2. Transportation

17 Light Rail and Tram System Backbone of public transports in the city (70 % of passenger volume) Network: 30 km tram tracks Service: 7,5 min service, better service at rush-hours Separate tracks, priorization at all junctions

18 Tram network development since network /

19 Extension of the tram network priorities Extension NORTH- WEST Extension NORTH network 2008 Inner city BYPASS

20 More environmentally and city-friendly vehicles Electric car sharing Hydrogen-based vehicles Fuel cell vehicle (Mercedes prototypes) First fuel station (built in Feb 2012) Power from solar cells 3 electric smart cars used by municipal administration First charging stations in operation Power from renewable energy Electric bikes Pedelec Motorbikes

21 Changes in Mobility: Bicycle

22 Changes in Mobility

23 3. Energy Three basic pillars of Freiburg s energy policy 1. Energy saving 2. Efficient technologies 3. Renewable energy sources

24 Renewable Energy: Wind & Cogeneration 5 wind mills in the city area electric power: 9,000 kw in total current production: 14 million kwh p.a. heat and power for the entire city district Vauban total electricity from biomass in Freiburg 16.6 million kwh p.a.

25 Projects: cogeneration all over the City March landfill Gundelfingen Currently 180 CHPs Power station Rieselfeld Landwasser WKV co-generation power station Zähringen Herdern university clinic Co-generation District heating Weingarten Haslach Wiehre Ebnet St. Georgen Vauban Littenweiler Merzhausen Günterstal Kappel Au

26 Solar Power as part of the German Energiewende trade fair center landfill site electric power: 700 kw p soccer stadium electric power: 100 kw p largest PV facility in Freiburg surface: 17,900m 2 covers current demand of 1,000 households/year capacity: 2.5 MWp second largest PV facility in the state Baden-Württemberg

27 Heliotrop Concept building completed in m² of solar panels (PV) on the roof, made from 60 modules of monocrystalline silicon (Siemens M 110L). In addition, attached to the balcony railings are 34.5 m2 of vacuum tube collectors, which provide high energy gains for hot water and heating.

28 Solar Power in Freiburg Currently Freiburg s 150,000 m² of photovoltaic cells produce over 10 million kwh/year. The 60 plus-energy homes of the Solar Settlement create more energy than they consume, and earn 6,000 euros per year for the residents. Solar thermal (mostly hot water) panels cover 16,000 m², but their total contribution to Freiburg s energy supply has not been quantified.

29 Green Tec and Solar Economy Research & Application of Solar Energy Region of Freiburg employees, more than 3% of the working population 650 million added value, 4% of the region s gross domestic product (GDP) companies The Freiburg Mix environment & climate skills & creativity politics & civic involvement
