DAYLIGHT FACTOR DISTRIBUTION IN INTERIOR BASED UPON THE MEAN SKY

Daylight illuminance is one of the most important element which comprises the luminous environment by daylight both in interior and at outdoor of building. Daylight is taken into interior mainly through the window. Therefore, the plan of daylighting is closely connected with the design of openings such as window. Examples of application for daylight factor distribution in interior were calculated in several rooms with facing several orientations by using a simulation technique. The outstanding characteristics of the daylighting prediction relying upon the Mean Sky are that the effects of the orientation of windows can be revealed.
