Brian Edwards explains the new responsibilities and opportunities for architects emanating from environment laws and directives. The practice of architecture is increasingly constrained by new legislation aimed at protecting the enviromnent and the consumer, mainly the result of directives from the European Commission. The broadening of environmental controls means that questions of environmental assessment, impact on ecosystems or heritage sites, energy use, safety requirements and environmental audits have become part of the daily life of architecture. The effect of the legislation is to create a new architectural order where low ecological impact and minimum energy use generate the form and style of building. In this essential reference book, Brian Edwards and a team of expert contributors set out the important principles which may help in the practice of architecture. As fresh controls are enacted, new skills and knowledge are needed which this book outlines through principles and case studies.
