Model for an optimized energy efficient lighting application for offices and open-plans offices The knowledge about the role of ipRGC and melanopsin in the humans life lead to a new view of what an energy efficient lighting application is. Lighting applications in offices is a common type of application in the indoor environment and need to be designed to support the human diurnal rhythm and sensitivity to view lit surfaces. The project has the ambition to use the varied levels of daylight from the window and into the deeper parts of the room to meet the user’s preferences of light. During a year will the level of daylight be measured and a complementary artificial light be designed. The project have the ambition to show how many days the daylight worked well as ambient light during the year and for how long time the user could be compensated by the use of the task lighting and a limited number of luminaries in the inner part of the room instead of using all the complementary artificial ambient light installed in the roof. Based on data from the study is a model designed that have a great potential in energy efficiency and is designed close to the individual users needs for light.
