  1. 1. European Urban Design for Sustainability Freiburg, Germany
  2. 2. BACKGROUND Population 220,000 Area (km2) 15,306 Percent green space/parks/nature 47.1 Hectares per capita green space/nature 0.031 Percent forest cover/forest canopy 42.4 Percent trips made on public transit 18 Percent trips made walking 23 Percent trips made bicycling 27 Greenhouse gas emissions per capita 0.468 Average size of houses/flats (in m2) 74.46 Meters of bikeways per person 0.78 Meters of public transit lines per capita 0.15
  3. 3. PLANNING CONTEXT Postwar Rebuilt: Old plot & heritage protection Population Accommodation: Within the existing built area Re-densification: Integrated function, fresh cell infill to promotes old and new designs
  4. 4. LANDSCAPE PLANNING Strongly influnced by regional planning: Each state identify, classify, and plan protected areas via state-level landscape plans Hierarchy open space down to local level Building permits only after the assessment
  5. 5. AIRFLOW ENHANCE STRATEGY  Restriction on building height and placement  The applications of green rooftops  Arrangement of streets and open spaces to facilitate the air from the hills through the city.
  6. 6. WATER MANAGEMENT  On-site management of stormwater: green roof, bioswales  Billing system: based on the volume of stormwater removed from individual properties (metric by impermeable property&estimated rainfalls)
  7. 7. TRANSPORTATION BIKING &PEDESTRIAN  30-kmh speed limit and banned in center city for cars  Over 152 miles of bituminized and 103 miles of gravel bike path  Enough parking spaces for bikes
  8. 8. TRANSPORTATION PUBLIC TRANPRTATION:  Over 17 miles of light rail and 168 miles of bus network have been developed since 1960  over 72% of all commuters use the tram system  residential planning coordinated with tramlines ( 90% within a half km to a station )
  9. 9. TRANSPORTATION TOLLING POLICY Single-fare system (Öko-Ticket): All transit within the city, Valid in RVF transport (60 km2) Transferable to family menbers
  10. 10. ENERGY&CLIAMAT CHANGE STRATEGY Energy conservation Renewable energy research Sustainable technology & transportation
  11. 11. ENERGY INDUSTRY  Renewable energy and solar research institutions  Rent-free houses for new energy companies  Solar Region Freiburg: compensates for installing solar panels
  12. 12. ENERGY & COMMUNITY  Community Projects around cogeneration plant and transit-oriented  Passive home (15 kW/h/m2)  Retrofit old housing
  13. 13. CASE STUDY: Vauban The setting:
  14. 14. District map
  15. 15. Development:1993-2008
  16. 16. Main Objectives:
  17. 17.  Advantage:  Cost saving(up to 30%)  Influnce  Social contacts CO-HOUSING GROUPS Over 50 co-housing projects have been realized.
  18. 18.  The compact urban setting(mix-function)  Reduction of energy needed for heating(mutiple-floor &passive house)  Alternative forms of energy supply (solar energy, combined heat&power plant CHP) ENERGY CONCEPT:
  19. 19. MOBILITY CONCEPT:  No parking at the doorstep (community car park, speed limit, main road parking space)  Flexible car-free life( association for car-free living)
  20. 20. Results of a survey  And Vanban has the highest density of car sharing vehicles  Lowest ratio of cars to household in Freiburg
  21. 21. Achieve healthy and high quality of life for all people in this and subsequent generations. OVERRALL PRINCEPLE (The Freiburg Charter for Sustainable Urbanism) Spatial I. Diversity, Safety & Tolerance II. City of Neighborhoods III. City of Short Distances IV. Public Transport & Density Content V. Education, Science & Culture VI. Industry & Jobs VII. Nature & Environment VIII. Design Quality Process IX. Long-Term Vision X. Communication & Participation XI. Reliability, Obligation & Fairness XII. Co-operation & Partnership
