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 (for Beddington Zero Energy Development), this eco-village, unique in its kind, wants to demonstrate that "habitat can be thought of and built without degrading the environment. To achieve this goal, the designers of Bedzed seem to have achieved a gigantic life cycle analysis (LCA), which consists of evaluating the environmental impact of a product's life, from its realization to its scrapping. ... or recycling. But if usually, we establish the balance sheet of a tire or a television, in the case of BedZED, it is the whole life of a village (construction of housing, needs in energy resources, displacements, professional activities, life social, waste management ...) whose environmental, economic and social impact has been conceived and evaluated. To achieve the eco-design of this place of life of 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, London's leading charity dedicated to housing, in collaboration with the highly active environmental group BioRegional and architect Bill Dunster, renowned for their interest in solar homes. . A trio with both simple and ambitious designs, as explained by Jean-Paul Jeanrenaud, WWF International, association that supported the project from the beginning, and Pooran Desai, Director of BioRegional: "(...) Make the concept of sustainability something easy, attractive and cheaper. The overall goal was to enable people to live sustainably in a two-hectare ecological footprint, the average available environmental space per person in the world. And without sacrificing the comfort and benefits of a modern, mobile lifestyle. "
A bet won does it seem, because BedZED is not reserved for an elite "bobo" or extremist militants. More than half of the housing units were reserved by the Peabody Foundation for low-income families, and homes were sold at a price equal to those of the traditional market, with the additional cost of some facilities being met by income from businesses and offices developed in BedZED. Modern comfort is not sacrificed, bath and no shower in bathrooms, oven and electric cookers, washing machine individual ... The village also has community living areas: health center, sports club, golf course. 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 an inspiration to the housing program planned by the English government (1 million housing on 10 years!). South Africa, China and Portugal are forming partnerships for construction programs. All the English regions are engaged in a calculation of their ecological footprint and the construction of a macro scenario, and a global network is being set up to set up pioneering sites living according to the principles of sustainability demonstrated in BedZED, "says Thanh Nguiem, a volunteer member of the WWF Directorate-General, who started a Franco-British structure to import BedZED's approach to France. In France, the WWF, very enthusiastic, is already looking forward to programs of rehabilitation and construction of HLM according to the sustainable criteria of BedZED, in partnership with companies (Savings Bank, Nature & Discoveries ...) and big cities interested (Nantes, Lyon, Lille ....)
