Abstract: This thesis report presents results of physical experiment and simulation studies on the application of shading devices for daylighting on the east facade. Vertical shading was used to intercept the excessive solar radiation. BESim was applied as the computer simulation program to calculate illuminance on the workplane and cooling energy consumption. To validate this computer simulation program, a series of physical experiments were conducted. The scheme in this research is the use of daylight with supplemented lamp. The lamp was used to improve the daylight performance in the interior. The light on the room should be uniform with general lighting 300 lux. The more daylight penetration, the more lighting energy consumption can be reduced. The energy consumption on the simulation consisted of artificial lighting and air conditioner. Thus, daylight should be maintained in order to avoid excessive heat from the sun. Several scenarios were investigated, such as variation of shading device, glazing, wall insulation, and reflector. There were two variations of shading devices: with or without reflector. Meanwhile, there were green tinted, low-e, IGU (Insulated Glazed Unit), and heat reflective glass for the glazing types. With the economic analysis, the benefits from those configurations were accounted for. As the result, the cheapest glazing type, green tinted glass, was the most beneficial if integrated with insulation and vertical shading since having more daylight penetration depth. However, the use of reflector was much more costly so that it was not better than that of without reflector.
