An Automatic Optimization External Shading Component Based On Solar Radiation

With the development of society and the progress of human civilization, the world for resource conservation and green concept is becoming more and more active, coupled with China’s construction of the life more and more short, increasing building energy consumption accounted for the total social energy consumption, consumption of building materials in the production process of energy increases, architects began to focus on building energy-saving design itself, so the birth of green building.If green architecture is a new design goals, then generate the design is a new means to achieve the goal of. The so-called generation design, is a computer program by setting calculation rules and design target makes architectural design automatic design technique.Different from the traditional design technique is to generate the design emphasizes the design rules of logical reasoning, based on the mathematical system of powerful computer and data processing capabilities to generate conform to a series of design constraints, and then implanted the scheme evaluation system, so that the calculation more in line with the objectives of the possible scheme of automatic screening machine. Design is a new design technique, a certain extent make up for the lack of diversity in the process of architectural design, to avoid a lot of repeated work, thereby increasing the efficiency of the design work.As one of the green building design category, architectural shading design has the characteristics of simple and efficient, rational and correct shading can effectively control the solar radiation into the interior, reduce the energy loss caused by the cooling load of air conditioner in summer, and truly achieve the goal of energy saving building. Currently more and more architects devote their selves to shading design. At present, there are two shading design methods, it mainly include traditional shading design method and the computer aided design method, but Generative Architectural Design for shading research is the frontier field, so this paper attempts to use generative architectural design, in the same way, for the purpose of energy saving in green building, to research the design method of shading.This paper consists of four parts:the first chapter briefly introduces review of the literature, research direction, the content, aim, significance and the structure of the thesis. The second chapter introduces the research methods and approaches in this paper. In the experimental part of the third chapter to the fifth chapter for the paper, three kinds of typical shading components in eight orientations were optimized, as well as the methods on how to better achieve energy saving targets were analyzed and summarized. The sixth chapter is the experimental method of test and correction, mainly comprehensive shading device for two kinds of construction were designed. The seventh chapter, the main research results of this paper is summarized, this paper put forward the shortcomings and the subsequent research work is prospected.In this paper, the main research results are as follows:One is establishing a set of automatic optimization of outer shading component based on solar radiation methodAnother is putting forward a set of the basic theory and practical experience about how to better achieve in energy saving design.The whole thesis contains about 66000 words,200 pictures and charts.
