Future horizons in building environmental engineering: A comprehensive and thought provoking presentation of how technology has been viewed at various stages of civilization with particular reference to environmental systems, both active and passive. A number of case studies are included

The paper brings together many current themes of interest and stimulates the reader to be aware that in creative work there has to be something beyond technical competence; there has to be a committed energy, desire and love in the work being created. The author confirms that buildings modify climate; they influence behaviour and culture; they affect the distribution of resources and the ecological pattern of our planet, whilst human aspirations can only be met when climate, buildings and people are in balance.
