Book excerpt: Visual Delight in Architecture examines the many ways that our lives are enriched by the presence of natural daylight and window views within our buildings. It makes a compelling case that daily exposure to the rhythms of daylight is essential to our health and well-being, tied to the very genetic foundations of our physiology and cognitive function. It describes all the subtlety, beauty, and pleasures of well-daylit spaces and attractive window views, and explains how these are woven into the fabric of both our everyday sensory experience and enduring cultural perspectives. All types of environmental designers, along with anyone interested in human health and well- being, will fi nd new insights offered by Visual Delight in Architecture. The book is both accessible and provocative, full of personal stories and persuasive research, helping designers to gain a deeper understanding of the scientific basis of their designs, scientists to better grasp the real-world implications of their work, and everyone to more fully appreciate the role of windows in their lives.
