BedZED (Figure 11.8) is a mixed development urban village constructed on a brownfield wasteland in the London Borough of Sutton, providing 82 dwellings in a mixture of apartments, maisonettes and town houses together with some work/office space and community facilities.22 The combination of super-insulation, a wind-driven ventilation system incorporating heat recovery, and passive solar gain stored within each unit in thermally massive floors and walls reduces the energy needs so that a 135 kW wood-fuelled combined heat and power (CHP) plant is sufficient to meet the village's energy requirements. A 109 kW peak photovoltaic installation provides enough solar electricity to power 40 electric cars, some pool, some taxi, some privately owned. The community has the capacity to lead a carbon-neutral lifestyle - with all energy for buildings and local transport being supplied from renewable sources.
