tElectricity is an important element used to run plant, lighting and other equipment in buildings. Anappropriate well-designed lighting system is required for energy saving since the lighting consumptionis dependent on the activities of the occupants of the buildings. Lighting consumption in a building canbe affected by the building’s purpose, the use of daylight, illumination levels and hours of usage by theoccupants. The present study aims at accentuating the use of computational modeling techniques towardssignificantly improving the effectiveness of daylighting control on energy and cost savings for historicoffice buildings. For this purpose, lighting performance of the Klang District Historic Office building inMalaysia was investigated through a simple daylighting control. The present study was carried out toinvestigate the lighting performance in a historic office building which is known as the Klang DistrictHistoric Office. Lighting performance is assessed using a simulation modeling that includes artificiallighting, daylighting, sun position, weather statistics, sky type, shading and a 3D Model. The study foundthat almost all cellular offices are adequately served by daylighting but that open plan offices needs someartificial lighting to supplement inadequate daylighting. The results are presented and the approachesfor energy saving discussed.
