Study On Optimization Design Of South Window Shading For Office Buildings In Xuzhou

With the rapid development of society and economy,the energy problem is becoming more and more serious.Climate suitability design is an important way to realize the building energy conservation and sustainable development.Shading optimization design combined with the construction window can achieve the goal of building energy efficiency,which can not only improve the indoor light environment and thermal environment,but also reduce the energy consumption of air conditioning and heating by effectively distributing the natural light and solar radiation.Based on the special climatic conditions in Xuzhou,Shading facilities must be able to fully block the sun’s radiation in the summer,but also to allow solar radiation into the room as far as possible in the winter,while ensuring the indoor light environment to meet the requirements of comfort standards.In order to solve this problem,the author takes climate suitability design as the basic premise,and studies from the following aspects:First of all,the author investigates and analyzes the present situation of existing office buildings in Xuzhou.The author points out the main points to design sun shading based on the analysis of the climate characteristics of Xuzhou.In addition,By investigation and analysis of the application status of sunshade in office buildings in this area,the author summarizes the existing problems and the reasons behind the present design for performance level,structural level and appearance level.Secondly,with the help of the method of numerical simulation,the author studies the optimization design of three basic external window sunshade to office building in Xuzhou based on the performance level.Based on the analysis of the influence of the south window shading on the solar radiation and natural lighting,the optimal design of the window shading is obtained.Finally,the optimization results window shade design based on the combination of practical engineering application,the Xuzhou construction office window shade comprehensive performance level,the construction level and appearance level requirements,and put forward appropriate design strategy.Based on the optimization results of three basic window-shading and combined with practical engineering application,the author puts forward the appropriate design strategy to optimize the integration of window shading and facade,under the requirements of performance level,structural level and appearance level.On optimization design of south window shading to office building in Xuzhou,the research is extended to the field of quantitative analysis combined with the requirements of indoor physical environment,which breaking through the independent product form as the key limitations.At the same time,it provides an important guidance and reference for architects in the architectural design stage,combining with the design methods and application of shading performance level,structural level and appearance level.
