Reyner Banham was a pioneer in arguing that technology, human needs, and environmental concerns must be considered an integral part of architecture. No historian before him had so systematically explored the impact of environmental engineering on the design of buildings and on the minds of architects. In this revision of his classic work, Banham has added considerable new material on the use of energy, particularly solar energy, in human environments. Included in the new material are discussions of Indian pueblos and solar architecture, the Centre Pompidou and other high-tech buildings, and the environmental wisdom of many current architectural vernaculars.
