"As the need to slow climate change becomes increasingly urgent, growing numbers of people are looking to dramatically reduce the carbon footprint of their own buildings by using more ecologically sound techniques. Ecohouse provides design information about the latest low-impact materials and technologies, showcasing the newest and best 'green' solutions with international case studies demonstrating sustainable design in action around the world." "This edition has been expanded to include advice on powering ecohouses using renewable energy - including wind, micro hydro and heat pumps - and an introduction to low-impact building materials such as lime, earth and hemp. New case studies from across the globe have been added to inspire readers with real-life examples of how to make an ecohouse work."--Jacket.
