Research On A Systematic Evaluation For The Natural Lighting And Heating Via Building Elevation

As the globe is getting warmer today,sun radiation is affecting people's lives more sevier.Architectural adumbral system,as one of the main method for people to avoid the sin radiation,and the design of it had been the important part to the western architects.Architectural adumbral system is becoming one medium to express the zone and culture characteristic of the architecture besides saving architecture energy,improving illumination and coziness indoor in summer.This thesis focus on the method of the adumbral system,selecting and designing of the adumbral system is an important aspect in architectural design. As a result this thesis coordinates,classify,analyse and summarize the methods of a the architectural adumbral system.Firstly,aiming at the thin basis inside and the laging concept of the architectural adumbral system design,this thesis clarify the background and the meaning of the architectural adumbral system,and pack up the interrelated theory of modern society in and out of country;Secondly,this thesis briefly review the process of the architectural adumbral system and resumptively introduce the architectural adumbral system after explainating the correlative conception and operated principium of.Then classify and analyze the characteristic and the applicable range from different point of view after knowing about the complex kinds and disadvantages;Thirdly,there is no doubt that function is the basis,and good technic and configuration are essential part of the architectural adumbral system.Therefore,comprehensively analyze the characteristic on the function, technic and form of the architectural adumbral system.All above three are either restricting or considering.Sun-shading of building will keep off the radiant heat of the sun,but how much will be kept off and how to evalue the efficiency of Energy Saving,have not be defined.In our country SD is the only parameter to evaluate the efficiency.But,tu calculate SD is not easy for the process of the radiant heat into the house is complex.The hight and the azimuth of the sun is changing everytime,too.So there are much method to calculate SD can not flect both two aspect.Considering the fact upwards,this thesis bring forward a evaluation of sun-shading system which is able to comprehensively evaluate the efficiency of enerage saving.the output data will help designers to choose the right sun-shading for the building.
