Kronsberg city is an ecologically-focused suburban development built on 1,200 hectares in Hannover, Germany for the 2000 World Exposition. The development aims to house 15,000 residents in 6,000 dwelling units while reducing CO2 emissions by 60% and waste by 50% through sustainable construction practices. These include constructing low-energy homes, implementing district heating, maximizing open spaces, and managing rainwater drainage naturally. Transportation primarily relies on an efficient tram system and extensive pedestrian and cycling paths to limit car usage.

Introduction
Kronsberg city is suburb of Hannover .It will showcase of creativities
on urban development ecological and social planning a new city district
created for the future to make manifest the world exposition themes,
'Humankind, Nature, Technology' in everyday community life.
Kronsberg was built for 2000 World Exposition on a 1,200
hectares site located in the southeast of Hannover, Germany. The
project aimed to build an ecologically-sound suburban community.
Once finished, Kronsberg is expected to have a total population of
15,000 residents and approximately 6,000 dwelling units.

3. Objectives
 Reduce CO2 emissions by 60% compared to current standards for
conventional residential buildings, primarily Kronsberg through Low
Energy House (LEH) construction methods.
 Reduce household waste by 50% and construction waste

5. Kronsberg
Approx. 80% of building land
owned by the City
 Approx. 50% subsidized housing
Overall concept enforced through
clauses in land sale contracts and
planning permission contract
 300 units – 2 story private terraced houses
 2,700 units in 3–5-storey apartment houses

6. Transportation of Kronsberg
Environmental compatibility and the
compact community were the paramount
aims of transport planning for the
Kronsberg district. A new direct tram
service links the settlement with the city
center. There are three tram stops located
along city so that nobody has to walk
more then 600 meters to reach a tram.
Journey time to the city center will be
just 15 minutes.

7. Traffic Calming
Traffic calmed street

8. Footpaths and Cycle ways
To complement the street layout a finelybranched network of paths is laid through the
quiet inner courtyards of the district which,
with their more private character, offer safe
play spaces for children
All streets and paths in the district give access
to the attractive footpath and cycle way
network in the surrounding countryside.

9. Parking Space
Car parking spaces are provided partly in
underground garages in smaller facilities.
Exploiting the local topography.
To reduce the number of parking spaces in
the
inner
courtyards
for
the
general
enhancement of public spaces, the City of
Kronsberg passed a by law permitting just
0.8 of a parking space per dwelling (instead
of the standard one space per dwelling.

10. Open Space Quality
The Kronsberg district has a great deal of open
space and intensively designed green space.
Each building plan was complemented with a
qualified open space plan by a landscape
architect who had to meet the high design and
ecological standards set by the municipality.
Border avenue between the new development
and the countryside
• Park corridors
• Neighbourhood parks
• Green inner courts

11. Environment
Ecological Standards Energy
 Energy Efficiency Optimization at Kronsberg

12. Co2 Reduction
60% less CO emissions through:
 Low Energy House (LEH) construction methods with quality assurance
monitoring
 district heating network, supplied from CHP plants
 electricity saving programme

13.  District heating
 Decentral cogeneration heating plant
 Compulsory connection to the network
 Only 5% more expensive than new-build developments with district heating
connections elsewhere in the city

14.  Low Energy Houses
All buildings in the Kronsberg district have been erected as Low Energy Houses
(LEH). Every building must use less than 55 kWh per m2 and year for space heating, verified
through a quality assurance programme.
 Electricity Saving Measures
A wide –ranging electricity saving programme is implemented at Kronsberg,
aiming to reduce the usual domestic electricity consumption by 30% from an average
consumption of 2,500 kWh to 1750 kWh per household and year , the national average lies
between 2,800 and 3,000 kWh

15. Solar City
 Solar district heating system
 Passive solar houses
 Photovoltaic cell technology

16. Passive House
In 1998 pilot project of 32 passive
Houses at Kronsberg
Energy consumption just 15
kWh/m2 p.a.
Passive house

17.  Wind Energy
 The most important renewable
energy source on Kronsberg is wind
power.
 Tow large and one smaller wind
turbines to provide enough energy
for 3,000 houses

18. WATER MANAGEMENT
The Kronsberg water concept, based on this ideal, takes three courses:
1. a rainwater management system following natural principles as part of the
registered EXPO project
2. drinking water economies across the entire district

19. Rainwater Concept at Kronsberg
Conventional construction
fewer sealed surfaces
paved and built-up surfaces
permeable surfaces on e.g. car parks
Rainwater runs off into the sewers.
groundwater infiltration
alternative flood protection measures
