Analysis Of The Double Skin To The West Wall Combined Shading Classroom In Primary And Middle Schools In Chongqing

Primary and secondary schools are indispensable educational place in the city. For a long time, The teaching building mainly uses the air conditioning equipment to adjust the indoor thermal environment, ignoring the effect of shading technology, which makes the teaching building has become one of the energy consumption of the building. However, suitable shading design can not only reduce energy consumption, but also can improve the indoor light environment. It is the only way to the sustainable development of teaching building.Chongqing area belongs to the hot summer and cold winter climate zone, and due to the special topography, resulting in many construction inevitably toward or bias from east to west, or toward the southeast, southwest. In order to ensure the comfort of the indoor thermal environment, the teaching building in the area mainly adopts the form of internal and external shading, which causes the indoor temperature is too high and the air conditioning system is used to cool down. The architectural design stage is rarely considered suitable sun shading design to increase the energy saving potential of thermal comfort, this is the topic of this paper is the origin of. Because of the special use of the teaching building, students need better indoor thermal environment, Therefore, this paper aims to study the impact of the west to the external walls of the primary and secondary schools in Chongqing, and put forward reasonable measures for the design of double skin facade, and through the simulation of indoor energy consumption and indoor light environment to optimize the design, so as to integrate with the architectural design of the strategy.This paper is divided into 6 parts: the first chapter is the introduction, put forward the research background, object and scope, introduces the background and significance, content and framework. In the second chapter, through the analysis of meteorological data of Chongqing, from primary and secondary school classroom thermal comfort and energy saving requirements of exploring double skin shade on the improvement of indoor thermal comfort, west of argumentation to the feasibility of double skin; primary and secondary schools the energy consumption characteristics of classroom analysis. In the third chapter, by the double skin form elements and interface elements of using induction and statistics and other research methods, from the point of view of the design analysis of its relationship with shade; and to explore the openings way, position openings and double skin between spacing and shading related basic data, the formulation plan for the next step of simulation. Through the second and the third chapter full of problem understanding based on, the fourth chapter according to the relevant norms, survey data and data statistics to develop universal and representative simulation prototype; and the Chongqing region meteorological parameters, simulation software of building lighting and energy consumption were calculated using the radiance lighting design software and Energy Plus energy consumption, it is concluded that the optimal openings way, between the opening position and double skin spacing with architectural design is closely related to the design strategy. The fifth chapter is the combination of building shading technology and architectural aesthetics, the building skin design trend of development of the status of the double skin facade combination are summarized. The case to illustrate the development trend of double skin composite exterior wall. In the sixth chapter, a summary of the thinking at the same time, the lack of research and prospects of the.In the actual design, due to the construction and regional micro climate complexity, resulting in simulation and the reality of a certain gap, only through the relative case comparison to illustrate the validity and feasibility of the design strategy; however the significance of writing this thesis in addition to the sunshade design strategies, more important is reflected in the provision of research methods and ideas of reference.
