From the viewpoint of architectural energy saving, this study discussed the impact of egg-crated shading device on lighting under natural lighting conditions, proposed a more proper module of sunshade with better lighting efficiency under the condition of different variables after making a comparison between the theory and the experiment, and established the basic profile regarding egg-crated shading device’s lighting efficiency. The study objects were established based on the experimental data of egg-crated shading device’s lighting efficiency. The theoretical basis of this research is the concept of lighting’s “daylight factor”. The method was to test the interior “daylight factor” of different sunshade models in an architectural scale model and compared the data with the experimental data established under diffuse light to discuss egg-crated shading device’s lighting efficiency under natural lighting conditions. This study includes the following content: Chapter　1 To point out the research motive，subjects，method and procedure. Chapter　2 Research trend and results of related studies in Taiwan regarding architectural energy saving and environmental control were summarized from relevant literatures in order to clarify the correlation of each research theme so as to understand and pinpoint the direction and scope of this thesis. Chapter　3 This study explained the development background of sunshade scale model, the method of setting up the environment for model testing, each part of the experimental model and the procedures. Chapter　4 “Daylight factor” and “Average Uniformity” were applied to analyze the lighting efficiency of each experimental module of egg-crated shading device design in order to obtain the more proper module of egg-crated shading device under the condition of different variables. Chapter　5 The experimental data of this study were arranged, compared and explained with that of the results under the environment of diffuse light. Chapter　6 The research results and conclusions were provided, and practical suggestions were proposed to future studies.
