HANNOVER,KRONSBERG,GERMANY

The Kronsberg district (Hannover, Germany) presents a comprehensive example of visionary urban planning and construction

Kronsberg is a settlement with exceptionally high ecological standards, buildings offering above-average quality of accommodation and semi-natural open space design

The district represents one of the largest and most advanced settlement programmes of its kind in Europe.

COMPACT STRUCTURESDecreasing density and building height as one

approaches the countrysideThe appearance of the district is shaped by its wide-

meshed rectangular grid layout, which creates frames for very varied block structures. 

The built-up, urban quality of the townscape is the result of design parameters that set the number of storeys, building heights and building lines along the streets

Along with the demand for compact structures, an important condition was that all corner plots should be built on.

COMPACT STRUCTURESAt the centre of the district, right next to

Kronsberg tram stop, it is the district square, on which are grouped:

Krokus arts and community centreProtestant church centreA health centreA shopping centreOther shops, café and restaurants

TRANSPORT A new direct light rail transit service (Stadtbahn) links the settlement with

the city centre Three light rail stops are so located that nobody has to walk more than 600

metres to catch a tram The main motorised traffic flow is channelled along the edge of the

development beside the light rail line to minimise nuisance to residents Planning of the residential street layout permits no through traffic Narrow sections on the roads, 30 kph zones, and priority to the right at

junctions, are effective traffic calming measures Car parking spaces are mainly arranged in small areas, either set into the

hillside or at ground leveL To reduce the parking space needs in the inner courts, a parking space ratio

of 0.8 per apartment was set at Kronsberg  A cycle-friendly street layout with a designated cycle street running the

length of the district offers, together with a dense network of rural and urban footpaths, an attractive alternative to private motorised transport.

ENERGY

A ‘Low Energy House’ standard was set for the entire Kronsberg development, meaning that the residential area has successfully

managed to reduce carbon dioxide emissions by 60% compared to conventional new construction in Germany. (The theoretical heating demand of homes on Kronsberg is a maximum 45-

55kWh/m2 per year, the German average is 200kWh/m2 per year.)

The site features a ‘Passive House’ development of 32 terraced houses requiring almost 90% less heating energy than

conventional terraces (15kWh/m2per year), due to 400mm insulation, extremely airtight structures, air extraction plants with

heat recovery, triple glazing and solar thermal collectors.

The district is served by two decentralised natural gas CHP (combined heat and power) plants, enabling

further carbon reductions.

Two large new wind turbines at Kronsberg (1.5MW and 1.8MW), together with an existing 300kW roughly

meet the electricity needs of residents across the district.

104 social housing apartments are heated from around 1350m2of solar collectors, that also feed

into a sunken thermal storage tank, meaning that solar energy can be used from spring through to

December, covering around 40% of the total heating needs of the homes.

WASTE

Recycling stations for pre-separated waste such as paper, packaging and organics, are situated through the neighbourhood and underground glass recycling bins help minimise the visual impact of such facilities.

Consideration was given to waste minimisation during the construction of Kronsberg and excavated soil was re-used in local landscape features to avoid it’s transportation to land-fill sites i.e. in raising the noise buffer embankment along the nearby motorway.

RECYCLING BINS

WATER

Method of rainwater management

used to maintain the natural water resources of the district.

Rainwater is collected from the entire Kronsberg site and carefully sent above-ground through various systems designed to retain the water and allow it to drain into the ground.

Kronsberg ponds, basins, ditches and channels are at times designed, sculptural elements and at other more natural and organic in form.
