The course is divided into two parts. It starts with a theoretical instruction and includes topics of light and lighting in relation to standards and recommendations, calculation methods for use in design of daylight and electrical lighting systems, colour and colour rendering of light sources, and photometry. Furthermore, connections are made with visual perception and physiology of the eye. The most important qualities of a lighting system, such as luminance ratios, avoiding discomfort and disability glare related to a task are discussed. The knowledge will be tested in an written exam. The second part of the lectures discusses the use of computer software for supporting lighting design calculations. A report including an analysis of a lighting situation both measured in the daylight simulator room and calculated using two software tools, is part of the final course mark.
