As the UK’s cities expand rapidly, problems are being caused for councils who have to meet the demand for housing. In addition to this, energy prices and pollution levels continue to increase. A solution has been developed by the Peabody Trust who have worked with environmental experts to build the Beddington Zero Energy housing development (BedZED) in Sutton, England. This unique development is an environmentally-friendly community of a hundred homes including gardens, offices, and childcare facilities with plenty of surrounding green areas. BedZED’s designers have created an attractive, affordable, urban village whose unique features benefit instead of harm the local community and environment. BedZED is a ‘zero energy’ development – no fossil fuels (coal and gas) are used and homes do not waste energy. Building materials are mostly natural, renewable or recycled. Houses face the south so that they get plenty of sunlight and their roofs are also fitted with solar panels, which change the sun’s energy into electricity. The windows consist of three layers of glass to stop heat from escaping. The homes are also fitted with the most modern energy-saving appliances. It is estimated that families’ electricity bills could be reduced by up to 60% whilst heating bills could be reduced by as much as 90%. Developers hope to achieve a 50% reduction in fossil fuel use by residents’ cars over the next decade by reducing the need to travel. Some residents will have the opportunity to work within walking distance of their homes. The Peabody Trust also aim to set up Internet shopping so that food can be delivered by local supermarkets. As the need for environmentally friendly, low-energy housing increases, BedZED may change from being a unique model, to a model for all future houses. 34.Cities in the UK ______.
