Oxford Ecohouse
# Oxford Ecohouse

Oxford Ecohouse is a house in Oxford designed to maximise energy efficiency. It is equipped with the first photovoltaic cell roof installed in Britain (in 1995). Situated in a suburban street in North Oxford, it was designed by Susan Roaf, a professor at Heriot-Watt University. A six bedroom family home, it produces only 130 kg $CO_2/annum$ per metre square, in contrast to comparable UK houses that produce 5000 kg $CO_2/annum$ m². It has 4 kW peak of photovoltaic output, 5m² of solar hot water panels and additional heating from a passive solar sun space. It was designed using low energy construction techniques, high thermal mass and a wood-burning stove to reduce carbon dioxide emissions by over 95%. The house has featured in a number of architecture books and is used as a research source in sustainable design.
