Reporting upon a study of environment which was based on the design of office buildings and office space, the study forms part of a continuing program of environmental research sponsored by Pilkington Brothers Limited of St. Helens, England. In this report the word 'environment' is used in the sense of the sum of the physical and emotional sensations experienced by people within buildings. The long-term aim of this research is the academic development of an understanding of this "total environment". This multi-disciplinary publication is accomplished by individual reports from the four research staff members--(1) a general survey by the architect of literature relating to office design and environment, (2) an account by the geographer of the general characteristics, population and location of post-war office buildings in England and Wales, (3) a report by the physicist of the results of surveys in offices of noise, lighting, and thermal conditions in winter and summer, and (4) a report by the psychologist of the response of the CIS (Co-operative Insurance Society, Ltd., Manchester, England) staff to their working environment and its implications for office design. Illustrations, photographs, charts, diagrams, appendices, and an index are provided. (KK)
