The author coordinates the many diverse branches of knowledge which have dealt with the field of lighting--physiology, psychology, engineering, physics, and architectural design. Part I, "The Elements of Architectural Physics", discusses the physiological aspects of lighting, visual performance, lighting design, calculations and measurements of illumination levels, daylighting, glare and visual comfort, reflectance, and color. Part II consists of edited reprints of papers previously published by the author and his colleagues; these papers have been grouped to correspond with the chapters of Part I. Photographs, diagrams and charts appear throughout the work. (KK)
