The targeted use of natural and artificial light not only effectively highlights the architectural design of buildings and interiors but also influences the energy efficiency of buildings, particularly non-residential ones, which must be demonstrated. Optimal access to daylight and appropriate artificial lighting, for example, enhances comfort in living spaces and productivity in the workplace. The practical handbook on light and lighting presents suitable lighting concepts and solutions for various spatial and usage requirements. In addition to the fundamentals of lighting technology and perception psychology, normative guidelines, and technical possibilities, it focuses on concrete design, planning, and construction execution.
