Potential of Shading Device in Enhancing Thermal Performance and Daylighting in Office Space of Industrial Building

Due to the global warming effect, the application of shading device in current building design is increased to enhance thermal comfort and daylight in the building. This research focuses on office space for industrial building, which is the most significant space due to it’s high usage. Therefore, this research is conducted to investigate the indoor thermal and daylight conditions, and to determine the potential shading device to enhance thermal comfort and daylight in the office space of the selected industrial building. The methods employed by the research are field measurement and computer simulation using Sefaira software. This study identified that after the shading device are added, the average indoor operative temperature of studied space decreased by 6.3% to 8.72% and achieved the required temperature for thermal comfort, which is 30.17°C to 30.34°C. The suggested optimum size of shading device is M4, which is the combination of both horizontal shading device and vertical shading device, and sized between 0.5m width and 2.0m height for each panel. This study suggests that the width of shading device should be 0.5m minimum and 1.0m maximum because this study identified the size that beyond this range can affect the quality of daylight inside the studied space. This research suggestions might help the building industries to provide the optimum size of shading device for reducing the average indoor operative temperature of the office space, in turn, the indoor thermal comfort can be enhanced and the optimum daylight factor can be achieved.
