Bed. ZED claims to be the UK’s largest sustainable community. Built in 2002, it has 100 homes designed to provide ordinary people with a high quality of life while living within their share of the earth’s resources.
Bed. ZED, in Beddington, south-west London, was built on a brownfield site on previously industrial land. Fifty per cent of houses are for private sale or rent, 25% for shared ownership and 25% social housing for rent Photo: Bio Regional
In a Bed. ZED home energy use for heating and hot water is reduced 81% by simpl things like south-facing windows and triple glazing. Electricity consumption is reduced 45% by low-energy lighting and appliances
Bed. ZED walls are thicker than average, with insulation between the bricks to prevent energy loss. The building materials have used less energy to make and, where possible, are locally produced
A combined heat and power plant was designed to burn Bed. ZED waste to produce hot water and electricity. But technical and commercial difficulties mean the system is not in operation and will be replaced. Effluent from the buildings is treated on site and the water is used for flushing toilets
A distinctive feature of the buildings is the wind cowls on the roofs. These cowls ventilate the houses and recover heat from the air coming out. The roofs are covered by solar panels (to generate electricity) and plants (for insulation and a habitat for wildlife)
People separate their waste in their kitchens to make recycling and composting easier. Sixty per cent of waste is recycled, three times the UK average. Residents encourage each other to recycle
Bed. ZED has a green transport plan to reduce car mileage. There is a carsharing club and electric car charging points. Good public transport links and cycle storage spaces are also provided
