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.

Hannover, Kronsberg, Germany

Introduction

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

Kronsberg

Approx. 80% of building land

owned by the City

Overall concept enforced through

clauses in land sale contracts and

planning permission contract

Approx. 50% subsidized housing

2,700 units in 3–5-storey apartment houses

300 units – 2 story private terraced houses

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.

Traffic Calming

Traffic calmed street

Footpaths and Cycle ways

To complement the street layout a finely-

branched 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.

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.

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

Environment

Ecological Standards Energy

Energy Efficiency Optimization at Kronsberg

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

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

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

Solar City

Solar district heating system

Passive solar houses

Photovoltaic cell technology

Passive House

In 1998 pilot project of 32 passive

Houses at Kronsberg

Energy consumption just 15

kWh/m2 p.a.

Passive house

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

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

Conventional construction

paved and built-up surfaces

Rainwater runs off into the sewers.

fewer sealed surfaces

permeable surfaces on e.g. car parks

groundwater infiltration

alternative flood protection measures
