BedZED: the first eco-village is born
In England, developers committed to sustainable development have for the first time created an ecological village driver without use of fossil fuels and without rejection CO2. A fascinating experience, from Switzerland to South Africa, already exports. In France, under the leadership of WWF, of public housing programs should follow this model.
At the time, France is increasingly alert communities about climate change, a pilot experiment conducted in Britain proves that practice sustainable development on the scale of a city can . In 2000, an ecological village, including 82 2 300 m2 housing and offices and shops, was born in the southern suburbs of London, Sutton.
Nicknamed Bedzed (Beddington Zero Energy Development), this eco-village, unique, wants to show that "housing can be designed and built without degrading the environment. "To achieve this goal, Bedzed designers seems to have realized a gigantic life-cycle assessment (LCA), which assesses the environmental impact of the life of a product, from its implementation until its disposal ... or recycling. But if usually we assess the tire or a TV, in the case of BedZED, the entire life of a village (housing construction, energy resource needs, travel, professional, life social, waste management ...) whose environmental, economic and social impact has been designed and evaluated. To achieve the eco-design of this living a new kind.
The first principle applied to sustainable BedZED is that of the local loop: use up to local resources, reuse and recycling (limited transportation, local economic development and strengthened cultural identity prévservée). Here 90% of materials come under 50 km radius (certified wood) and are often recycled (old rails railway ...). The housing design is thought in terms of energy efficiency and quality of life: reinforced insulation, sunshine, terraces and garden, ventilation system with heat recovery ... The use of renewable energy and the optimization of natural resources is BedZED project a great example of actual size that can be a reasonable use for resources: recovery of rainwater for toilets, electrical and thermal energy from biomass (waste wood), and the recovered heat photovoltaic panels on the facades. The electricity produced can even recharge 100% electric vehicles available to share with people.
The movements are reduced, since workspaces are available, that local shops have been created, and a fresh delivery system from the region exists.
Finally, this streamlining allows BedZED 50% to reduce its ecological footprint. To give an order of magnitude compared to conventional homes, the heating is reduced 90% of the total energy consumption 70%, and the volume of waste 75%.
Sustainable Habitat "easy, affordable and attractive"
BedZED was designed by the Peabody Foundation, the largest charitable organization in London devoted to housing, in collaboration with the BioRegional Development Group, environmental group active and architect Bill Dunster, known for his interest in solar homes . A trio the designs are both simple and ambitious, as explained Jean-Paul Jeanrenaud, WWF International, Association who supported the project from the start, and Pooran Desai, director of BioRegional: "(...) To make the concept of sustainability something easy, and attractive and cheaper. The overall objective was to enable people to live sustainably in a footprint of two hectares, the average environmental space per person in the world. And this, without sacrificing the comfort and advantages of a modern, mobile lifestyle. "
A sure bet seems as BedZED is not reserved for the elite "bobo" or militant extremists. More than half of the units have been reserved by the Peabody Foundation for low-income families, and homes were sold at a price matching those of the traditional market, the additional cost of some facilities being filled by revenues provided by the activities of retail and office developed BedZED. Modern comfort is not sacrificed, bathtub and shower not in the bathrooms, oven and electric cookers, washing machine individual ... The village is also equipped community living areas: health center, sports club, field games, nursery, cafes, restaurants ...
New villages WWF
BedZED was awarded in July 2000 by the Royal Institute of Builders and Architects (IRCA) and will serve as inspiration to housing program provided by the British government (1 million homes on 10 years!). South Africa, China or Portugal forge partnerships for building programs. "All the English regions has engaged in a calculation of their ecological footprint and macro scenario building, and a global network is being set up to establish living pioneer sites according to sustainability principles demonstrated at BedZED "welcomes Thanh Nguiem, volunteer member of the Directorate General of WWF, originally a Franco-British approach to import structure BedZED in France. In France, WWF, very enthusiastic, is looking forward to rehabilitation programs and public housing construction according to sustainable criteria BedZED in partnership with enterprises (Savings, Nature & Discoveries ...) and large cities interested (Nantes, Lyon, Lille ...).
