Ensuring that buildings are healthy and comfortable for their occupants is a primary concern of all architects and building engineers. This highly practical handbook will help make that process more efficient and effective. It begins with a guide to how the body (and mind) react to different indoor environmental conditions, explaining the problems that can result from poor design, and indicating optimum (benchmark) responses. It then moves on to give a background to the development of the study and control of the indoor environment, examining the main design considerations (including temperature, light, ventilation and noise) and discussing the drivers for change in the field. The final section presents a newly developed 'top-down' or systemic approach, where meeting the wishes and demands of the occupants with a holistic strategy becomes the overriding priority. The book is filled with useful facts, figures and analysis, and practical methods which designers who are keen to assess and improve the user experience of their buildings will find invaluable and can begin using straight away.
