Über dieses Buch
Throughout history, daylight has been a crucial factor in the design of buildings. Before the advent of artificial light (from oil lamps, gas lamps and later electricity), it was necessary to design buildings so that their occupants could make maximum use of available daylight. As a result building plans were narrow and window sizes large. Cheap electric light appeared to remove these constraints, allowing windows to be driven more by aesthetics than physical need, and plan depths to be increased to reduce overall building costs. We now know that this approach overlooked the vital importance of daylight's contribution to human comfort and satisfaction in indoor environments. Since the turn of the century, we have discovered evidence of the presence of a non-visual photoreceptor in the human eye, whose primary purpose is to regulate the body's internal clock and begun to model the behaviour of these receptors in human biology. In short, we are now beginning to understand the importance of exposure to adequate daylight levels for the health and wellbeing of humans, many of whom now spend most of their lives inside buildings.The purpose of this document is to guide the reader through the process of designing a building that is well daylit. Daylighting is a design process that needs to be rooted in both aesthetics and physics — art and science. As such, it is notoriously difficult to completely define a well-daylit building.
