BedZED, designed by British architect Bill Dunster, is an entire community of eighty-two homes in Hackbridge, near London, built according to eco-architecture principles. Houses face south to take advantage of sunlight and have triple-glazed windows for insulation, a significant portion of the energy comes from solar panels, rainwater is collected and reused, and automobiles are discouraged. BedZED successfully reduced electricity usage by 45 percent and hot water usage by 81 percent of the borough average in 2010, though a successful system for producing heat by burning wood chips proved elusive and difficult.
