The purpose of this research project is to present the methods for and important points relating to artificial lighting plans that are based on seated office workers' assessment of brightness in an office where daylight is utilized. In the brightness assessment experiment carried out by the authors, daylight was used as the ambient lighting and perceived brightness was assessed in offices with differing layouts, in which many chairs were used as objects. The results show that perceived deficiency of brightness was related not only to low luminance in the location in question, but also to position in the visual field, and to the types of surfaces. It was also discovered that the distance between an office worker and an object, as well as qualitative factors such as the importance of the object to that office worker, also affected the level of brightness perceived as necessary. These results demonstrate that the task and ambient lighting that would most effectively provide the needed brightness depends on the types of surfaces in the seated office workers' visual field, and how those surfaces comprise that visual field.
