The main subject of this study investigates the influences and effects that the shading devices shelter the direct sunlight at the building openings in the northern hemisphere. The issue in the study we continue to analyze the study of the sheltered effects about the Horizontal Shading Devices. In connection with the characteristic of Vertical Shading Devices, we use computer simulation programs imitate the screening method to analyze the building shading effects in different aspect ratios of openings and the depth ratio of shading devices. Moreover, we execute the simulated data of the cross-comparison and analysis with regard to different variable factors, and provide the suggestions and advices of the shading devices of the best structure which are located in different latitude area in the northern hemisphere. This study includes the following content: Chap 1 Main description of this study as motivation, range, method, restriction, process, and the expected outcomes of the research. Chap 2 Arrange and generalize the three main literatures the shading coefficient, the comprehensive assessment of the window Area and the economy and the consumption of the building, and the computer simulation. And understand the connections between the relevant researches to make sure the study area and restriction. Chap 3 Main description for the definition of shading ratio, depth ratio and shading devices module type. This study uses the operation and setting of mounted computer simulation program, the operating method of Sun-shade system simulation program and the above related setting of altered and fixed factors. Chap 4 Arrange and draw chart the shading ratio calculation which was simulated by computers, and to divide summer and winter in the northern hemisphere into three terms as year term, warm term and cold term by months. In accordance with these three terms, analyze the trend of depth ratio of Vertical Shading Devices, and the shading ratio of windows aspect ratio. Chap 5 According to the year term, warm term and cold term, Vertical Shading Devices would analyze the influences of shading ratio by changing the depth ratio and windows aspect ratio with various positions. Chap 6 According to the results of this study of shading effectiveness, we will bring up a conclusion in the light of position, latitude, windows aspect ratio and depth ratio of shading devices. Furthermore, we will provide the advices and suggestions about setting the building opening shading facility in the northern hemisphere.
