New lighting best practices, from a design-research collaboration
Evidence-Based Lighting Design explores how light affects human health and well-being, and provides real-world examples and guidelines for designers. Written by internationally recognized and award-winning lighting experts, the book combines design theory and scientific research to establish best practices for lighting design. Contributions by prominent medical and scientific researchers provide real evidence validating the long-held assumption that design impacts the users of the space, and the book expands upon the research to provide an accessible, easy-to-read guide to the theory, concepts, and practice of evidence-based lighting design.
Evidence-based design is a research-based approach designers use to understand how the built environment influences behavior. When applied to lighting, the evidence was made clear when the American Medical Association announced that lighting does indeed affect human well-being. The recent integration of scientific evidence into lighting design has become a top priority for lighting designers, and Evidence-Based Lighting Design is the first comprehensive reference in the field. The book discusses the results of research, and offers advice on incorporating these new guidelines into the design process. Topics include:
The book includes case studies that illustrate the real-life impact of lighting, exploring aspects like artificial environments, clinical environments, and the effects of light on plants and animals. The guidelines that result represent the collaboration of designers and researchers, making Evidence-Based Lighting Design the most complete field resource on the market.
Philip K. Dick is the author of science-fiction classics that have inspired movies like Bladerunner, Total Recall and Minority Report. Sadly, Dick did not live enough to see how his suspicion of reality and his search for the human essence in an artificial world became mainstream concerns and pop culture icons. Based on a careful review of biographical materials and his personal acquaintance with some of Dick's closest friends and relatives, Salvador Bayarri has written Dick's life story in a screenplay format, preserving the richness of the writer's character as his charming humor and foretelling genius mixes with a personal struggle to make sense of his own visions, the human nature and the meaning of the universe. "The Owl in Daylight" was the working title for Dick's last book project, in which he planned to create a character much like himself: a visionary artist who discovers that his work improves as an alien intelligence takes control of it. Blinded by his unique perception -like a night owl in daylight- the artist has to make the Faustian choice between reaching for the ultimate secrets of the universe and die in glorious flames, or trying to save the remains of a normal life. The screenplay follows the key episodes that propelled Dick to his prophetic visions, from the death of his twin sister shortly after birth, through the paranoia of the 50s and the psychedelic culture of the 60s, towards his final and most dramatic visions of love, good and evil.
It is remarkable how much we take for granted the tremendous energy and vitality that the sun provides earth's inhabitants. As we enter the new millennium, it is worthwhile to review how our ancestors perceived the biologic effects of sunlight, and how science and medicine have advanced our knowledge about the biologic effects of light. At the turn of the century, a multitude of investigators explored the use of sunlight and artificial radiation for treating a multitude of diseases. These explorations gave rise to photodynamic therapy, phototherapy, and chemophototherapy. However, enthusiasm for using sunlight and artificial radiation to treat disease was dampened with the birth of pharmacology. It was the goal of the Fifth International Arnold Rikli Symposium on the Biologic Effects of Light, held in Basel, Switzerland, on November 1-3, 1998, to review the history of phototherapy and have some of the world's leading experts on the biologic effects of light provide new perspectives on the positive and negative effects of light. The general topics included a broad range of biologic effects of sunlight, artificial ultraviolet radiation and electromagnetic radiation. Special sessions on radiation and vitamin D and bone health, photoimmunology, biopositive effects of UV radiation, effects of electromagnetic currents and fields, and ocular and non-ocular regulation of circadian rhythms and melatonin, should be of particular interest to readers of Biologic Effects of Light.
1.1 Overview We are living in a decade recently declared as the "Decade of the Brain". Neuroscientists may soon manage to work out a functional map of the brain, thanks to technologies that open windows on the mind. With the average human brain consisting of 15 billion neurons, roughly equal to the number of stars in our milky way, each receiving signals through as many as 10,000 synapses, it is quite a view. "The brain is the last and greatest biological frontier", says James Weston codiscoverer of DNA, considered to be the most complex piece of biological machinery on earth. After many years of research by neuroanatomists and neurophysÂ iologists, the overall organization of the brain is well understood, but many of its detailed neural mechanisms remain to be decoded. In order to understand the functioning of the brain, neurobiologists have taken a bottom-up approach of studying the stimulus-response characteristics of single neurons and networks of neurons, while psyÂ chologists have taken a top-down approach of studying brain funcÂ tions from the cognitive and behavioral level. While these two apÂ proaches are gradually converging, it is generally accepted that it may take another fifty years before we achieve a solid microscopic, intermediate, and macroscopic understanding of brain.
