碩士 === 淡江大學 === 建築(工程)學系 === 83 === There are three basic types of outdoor fixed sun-shading de- vices used in architecture design.Basically,they are horizontal, vertical,and egg-crated shading. This research chooses horizontal sun-shading and sun-reflecting devices as subjects , and day- lighting model and computer simulation were used as research me- thodologies. It is concerned that the expectation of contribution for the basic research of daylighting in architecture design. The interrelationship between light and heat is the cause of efficiency of indoor spacing influenced by daylighting and sun- reflecting devices, therefore,besides to fulfill the need of day- light, high efficient design of sun-shading is the best way to utilize daylight. The focus of this research is model test and computer simulation for simulating the efficiency of day-lighting and sun-shading. Model test is to test the outdoor/indoor illu- mination ratio of five categories for designed horizontal sun- shading and sun-reflecting shelf and translate the result to day- light factor in order to analize the efficiency of indoor day- lighting. As far as the computer simulation, base on taipei''s logitude/latitude, the calculation of corelation coefficiency of sun-shading from different altitude and azimuth of sun, according to different orientation in different time under the condition of different sun-shading devices. A graphical annual line chart will also be conducted according to collected data for analization. Finally, this paper will summarize the general efficiency of daylighting and shading, and compare the characteristic of the five different types of the day-lighting efficiency.
