The Study Of Ordinary Classroom Daylighting Based On The Form Of Side Windows In Chongqing

With the development of construction, the building energy consumption presentsgrowing faster year by year. Developing low-energy building has become the currenttrend. As we know, lighting energy consumption is a part of building energyconsumption. So making full use of daylighting can effectively reduce lighting energyconsumption. For the users of classrooms, daylighting occupies an important position.Comparing with lighting, daylighting can improve the comfort level, at the same time, itis helpful for improving the efficiency of teachers and students.This thesis regards the ordinary classroom in Chongqing as the main researchobject. After discussing the essentiality of daylighting in classrooms, the author studydaylight climate of Chongqing through the analysis of standard meteorological data inChongqing, Based on this, combining with Standard for Daylighting Design ofBuildings (GB50033-2013), the thesis indicates the problems of daylighting inclassroom through field research, data testing and analysis in Chongqing. To solve theseproblems, the author use daylight climate date and Desktop Radiance to analyze maincharacteristic parameters, such as the Ac/Ad, the transmittance of glass, the height, theform, the arrangement and the daylighting components of side window, which caninfluence daylighting, then concludes the relationship between these parameters and thequality of daylighting. The thesis research the optimization of daylighting though thedeeper quantitative analysis of parameters. Finally the author will put forward a set ofside window daylighting strategies suitable teaching building in Chongqing.The following are the main research works and achievements of this thesis:â‘ Theproblems of daylighting in classrooms are summarized through field research and alarge number questionnaires;â‘¡Based on standard meteorological data, getting daylightclimate date though radiation light equivalent model. After comparing daylight climatedate with design illuminance of exterior daylight in Chongqing, we can obtain that theactual illuminance of exterior daylight below design illuminance of exterior daylight(V)in certain month, and it should be amended;â‘¢The relationship between daylightingparameters and daylighting quality is studied through the Desktop Radiance simulation,proposed that adding daylighting components can effectively improve daylightingquality;â‘£Do further research about daylighting components and put forwardimplemented daylighting strategies.
