1. European Urban Design for
Sustainability
Freiburg,
Germany

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

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. 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. 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. 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. 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. 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. 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. TRANSPORTATION
TOLLING POLICY
Single-fare system
(Öko-Ticket):
All transit within the
city,
Valid in RVF transport
(60 km2)
Transferable to family
menbers

10. ENERGY&CLIAMAT CHANGE
STRATEGY
Energy conservation
Renewable energy research
Sustainable technology &
transportation

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. ENERGY & COMMUNITY
 Community Projects around
cogeneration plant and transit-oriented
 Passive home (15 kW/h/m2)
 Retrofit old housing

13. CASE STUDY: Vauban
The setting:

14. District map

15. Development:1993-2008

16. Main Objectives:

17.  Advantage:
 Cost saving(up to 30%)
 Influnce
 Social contacts
CO-HOUSING GROUPS
Over 50 co-housing
projects have been
realized.

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:

20. 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)

21. Results of a survey
 And Vanban has the highest density of
car sharing vehicles
 Lowest
ratio of cars
to
household
in Freiburg

22. Achieve healthy and high quality of life for all
people in this and subsequent generations.
