| Summary: | 碩士 === 國立臺北科技大學 === 冷凍空調工程系所 === 105 === With the increasing awareness of sustainable and green building, more and more people are concerned with the efficiency of energy use at home and at work. A solar tracking skylight system, which enables us to conserve energy by producing increased interior light levels for a longer duration than normally possible, can fit to the above need and have widen been used in the indoor illumination gradually. In this study, an experimentally investigation is conducted to explore the dynamic illuminative performance of solar tracking skylight illumination system and Compound Parabolic Lighting Duct System. In the first stage of this research, a tracking skylight system is tried to be developed by implement. In the second stage, the experimental test apparatus is set up and the basic lighting intensity distribution of skylight illumination system will be examined. In addition, the effects of various design parameters, the material of reflective panel and diffusive panel, the sensitivity of tracking skylight illumination system and skylight condition, are also analyzed. The results show that (1) illumination of indoor room can reach 200Lux, which fit the rule of Chinese National Standards (CNS), when the building is installed this systems under sunny day;(2) the accuracy of dual-axis solar tracking system developed by this study can up to 97%;(3) solar tracking skylight system get 29918 Lux illumination throughout the daytime, which equivalent to 0.59 kilowatt-hours per day. In other word, the energy saving of this system is about 10.92MW per year; (4) the compound parabolic lighting duct system gain 25712 lux illumination throughout the daytime, which equivalent to 0.5 kilowatt-hours per day, the energy saving of this system is about 9 MW per year; (5) the amount of energy saving of this sunlight catching system depends on reflectivity of the light guide plate, the size of opening area of solar tracking mechanism, the number of solar tracking system
