Description
- The site covers 38 hectares and houses more than 5,000 inhabitants and provides 600 jobs.
- Attractive district especially for young families. In 2002 more than 20% of Vauban inhabitants were under 10 years old. The demand for land was stronger than availability.
- The "Learning while Planning" principle
- The site was divided into small plots and allocated to private builders and Baugruppen (co-housing groups).
- About 40 co-housing groups were established alongside building cooperatives and the self-organized S.U.S.I.-settlement initiative. These initiatives enabled holistic public participation.
- Participatory planning during the building stage was a great success. Legal, political, social, and economic participants were integrated from a small grassroots level up to the city administration.
- Concrete objectives were achieved or exceeded.
- While the development plan included some design and layout regulations, builders were given the freedom to design homes to meet their own aspirations
- All houses were built with improved low energy standard, 65 kWh/m2a similar to the Swiss SIA380/1 standard.
- Around 150 houses "passive house" (15 kWh/m2a) or "plus energy house" standard, producing more energy than they use.
- A highly efficient co-generation plant (CHP) operating with wood-chips is connected to the district's heating grid.
- Good insulation and efficient heat supply creates CO²-savings of 60%.
- A large number of solar collectors and photovoltaic modules were installed.
- Around 65% of the electricity needed in Vauban is produced on-site through CHP and photovoltaic.
- Rainwater is collected separately for in-house use or filtrated into the ground.
- A new sanitary concept using vacuum toilets and biogas plants was introduced by one co-building group.
- Reduced number of private cars, good public transportation, and a car-sharing system.
- Streets and other public spaces became playgrounds for children or other public uses.
