Recently the Green Building Rating System has become commonplace around developed countries. Since 2002, Korea also operates a certification system and deployed increasingly. Within the Green Building Rating System of inner environmental part is the most important part among other countries certification as well as energy part. In fact, the general office tasks to use necessary artificial lighting to ensure proper illumination of the building, energy consumption is approximately 30% of the total electrical energy consumption. From the outside, using natural light aggressively can lower its dependence on large amounts of electrical energy. So in this study, design appropriate lighting due to the window area and several forms of rooms. From the room set the domain of secondary and artificial lighting (PSALI, Permanent Supplementary Artificial Lighting in Interior) when introduce natural light from outside the room. derive methods of using minimum artificial lighting under condition of proper illumination of indoor, by this method present best solution in case of lowering dependence by using natural lighting to save electricity energy, so that it can present basic data in the future of energy saving lighting design.
