AbstractDaylighting use for buildings becomes the innovative strategy for passive building design. There are many systems to harvest daylight for buildings and horizontal light pipe system is the most effective solution to transport daylight further to deep space. Horizontal light pipe can bring daylight to deeper area where daylight through window or other systems cannot reach that area. The purpose of this study is to investigate the theoretical potential of horizontal light pipe system for office building, and to demonstrate the light pipe and evaluate the performance. The horizontal light pipe system can be applied for any floor of the building at where other daylighting systems cannot provide enough daylight to the deep areas. Moreover, the light pipe can be installed within the ceiling plenum and comparatively cheaper than other daylighting systems. The light pipe is installed at facing East so that it can receive direct sunlight more in the morning that gives higher illuminance level while the illuminance level drops in the afternoon. According to the calculation of illuminance for the whole year and experiment for selected days, daylighting through light pipe can provide the required illuminance level of 300 lux for office building from 8:00 to 10:00 in the morning. On the basis of the results of this research, it can be concluded that utilizing light pipe can reduce electrical energy consumption by two fluorescent lamps that give the same amount of lighting level for two hours in a day.
