INTODUCTIONIn Germany today more, than 1,000 cities have startedactivities and programmes responding to the newvision of sustainable development, communicating it totheir citizens or devising development programmes. Inthis presentation we will chose Hannover’s Kronsberghousing area.
The main obstacles to implementation and reasons forthis low take-up are: the complexity of the new vision, especially inits global dimension. lack of information and communication atthe political and professional (academic andpractitioner) level. the not-yet-concluded process ofinterpretation - of how to apply the vision topractical planning processes a certain reluctance on the part of urbanplanners to accept the new paradigms
Kronsbergis a new eco-district in Hannover built on 1200hectares of mainly agricultural land. The district islocated in the South- East of the city.Kronsberg is close to the countryside, yet enjoying allthe advantages offered by an urban neighbourhood:excellent transportconnections, jobs, cultural, commercial , leisurecentres and facilities.When complete, it will comprise 6000 dwellings andwill be home to around 15000 people. Almost 3000new jobs have been created and are located in theimmediate vicinity.
ObjectivesThe main objective is to build a districtwith a good mix of functions(residences, leisure and culturalfacilities, commerce and agriculture) bytaking into account environmentprotection.Applying planning for sustainability inKronsberg placed considerableobligations on all stakeholders and localactors to ensure the highest possiblequality of life and to use naturalresources sparingly.
Financing structureKronsberg projects are fundedby a wide range ofpublic and private institutions,Energy Efficiency Optimizationat Kronsberg, asone of the most advancedsuch projects inGermany.The investments sum up toapproximately € 2.2 billion.
AchievementsWe can classification the achievement by five fields : Transport water Energy Waste Social
TransportEnvironmental compatibility and thecompact community were theparamount aims oftransport planning for the Kronsbergdistrict. A new direct light rail transitservice links the settlement with the citycentre (17 minutes). Three rail stops arelocated so that nobody has to walkmore than 600 meters to catch a tram.In the residential area the car access isforbidden, except for Kronsbergresidents, cycle paths ensure access toall facilities in the neighbourhood.
Energy(wind energy, solar); 2 cogenerationplants used for heating needs of thedistrict; energy efficiency measures wereforeseen concerning construction of newbuildings, training courses on low energybuildings were organized forconstructors; 77 washingmachines, 106 dishwashers, 122refrigerators were financed fromsubsidies.2 water saving devices and 5low energy light bulbs / household; intotal 5615low energy light bulbs weresubsidized, the equivalent of353MWh/year.
waterall precipitation on built-up and paved areas isabsorbed, collected and gradually released; equipment ofall apartments with water saving devices.
Wasteinnovative collection systems have been set; recycling rates ofapproximately 80% were achieved; during the constructionphase building waste was sorted on site; the excavated soil wasreused in the district for landscaping and environmentalenhancement.
Socialdifferent housing options (private apartments, social housing, 300 privatehomes); housing for disabled persons; housing for different ethnicrepresentatives; old people centre; private childminding; second-hand shops;tenants’ association; district council office; citizens’ environmental campaign.
Due to changes in growth patterns and adramatically lower demand for new housing unitsthan predicted in 1990, the Kronsbergdevelopment has been built at a much slowerpace than originally anticipated. Instead of theproject being completed by the year 2000, it isexpected that the development could stretch outover 10-15 years.
Positive experience from the Kronsberg project motivatedthe city of Hannover to set and extend ecological standardsto the entire city of Hannover taking into account severalaspects: energy, soil, nature conservation, waste, water andbuilding materials.As new building development in Hannover is very low, it isalso necessary and effective to apply ecological measures tothe existing building stock.
