Brenda Vale is a professorial research fellow at the School of Architecture, Victoria University of Wellington, New Zealand. Their 1975 book The Autonomous House is widely recognized as a basic text in the field of green building. Through the 1980s the Vales designed a number of very low energy commercial buildings and social housing schemes in England. In the 1990s they wrote Green Architecture, completed the first autonomous house in the UK and received the UN’s Global 500 award. They also designed the award winning zero-emission Hockerton Housing Project. They later developed the National Australian Built Environment Rating System (NABERS) which has since been commercialised. The Vale’s latest book: Time to eat the dog? Deals with the realities of sustainable living, and has been published by Thames and Hudson in June 2009.
