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. Use data of shading factors with horizontal shading devices and direct solar radiation in northern hemisphere to calculation the evaluation horizontal shading devices coefficient , 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 two main literatures the shading coefficient, the economy and the consumption of the building, and the structural purpose meteorological data. And understand the connections between the relevant researches to make sure the study area and restriction.
Chap 3 Main description for the definition of sheltered effects about the horizontal shading devices, direct solar radiation, shading devices module type and the above related setting of altered and fixed factors.
Chap 4 The goal is to provide designers of appropriate window orientation for building energy efficiency, analysis and draw chart the vertical receiving direct solar radiation energy value in different latitudes, different orientations and different season.
