The essential guide to understanding the future of sustainable technology. In this fully updated new edition, Professor Smith describes how buildings can be made to reduce their reliance on fossil-based energy with solar and geothermal resources. He also describes a range of renewable energy generating technologies. With the advance of climate change, government legislation and international treaties, this is valuable knowledge for every architect, engineer and designer. Packed with useful diagrams, charts and colour photographs to illustrate a variety of recent case studies, including the education building, the Core, at the Eden Project in Cornwall. As well as exploring cutting edge developments in photovoltaics (PV) this revised edition also includes the latest data from the 2006 Carbon Trust report on wave and tide, and new material on the latest advances in bioenergy and marine technologies.
