基于性能模拟和数据分析的窗装饰改造模式研究--以重庆地区住宅为例

Reserch on the Window Decoration Reform Mode bsaed on Performance Simulation and Data Analysis——Take the Residential Area in Chongqing as an Example

当前,重庆地区的建筑改造正在如火如荼地进行,改造方式多集中在窗装饰(遮阳雨棚等)方面,其设置方式主要有水平式装饰、垂直式装饰、综合式装饰和挡板式装饰四种。其中问题有二:一是因为安装目的以防雨为主,因此就遮阳而言效率较低。二是因为构件出挑的尺寸和相邻外墙窗户的关系都没有确定。针对上述两点,以能耗性能为导向,对现状建筑遮阳的设计模式进行量化探讨,找出符合该地区气候特征的窗装饰改造模式。总结模式的步骤如下:首先,对重庆地区现有居住建筑形式进行文献查阅,总结出适用于该地区的理想居住建筑模型;其次,基于理想建筑模型进行窗装饰构件形体样本的生成,采集生成大量随机样本,然后对生成的多样随机样本进行模拟分析,得到能耗基础数据;第三,通过人工神经网络对数据进行分析,找到参变量、因变量之间的复杂关系;最后,结合构件尺寸与能耗值二者的影响,在数据分析的基础上找到最优决策,得到适合该地区居住建筑不同方位上的窗装饰构件改造模式。

Recently,the architectural reconstruction in Chongqing is in full swing.The remold methods mainly have been focused on window decorations(awnings,etc.).The setting methods mainly include horizontal decoration,vertical decoration,integrated decoration and baffle decoration.Two problems exist:the first one is the installation’s inferior efficiency as a sunshade because the original purpose of them is the rain proof.The second one is the ratio of size of the components and the dimension of adjacent windows is not determined.Aiming at the above two points,this paper quantitatively discusses the shading design mode of current buildings based on energy consumption performance in order to find out the window decoration modes that conform with the climate of this region.The steps of this paper are as follows:Firstly,the paper reviews the existing residential building forms in Chongqing and summarizes the ideal residential building model suitable for this region.Secondly,based on the ideal building model,the form samples of window decoration components can be generated and a large number of random samples are collected.Then,this article simulates and analyses the various random samples to obtain the basic data of energy consumption.Third,through the artificial neural network,the paper finds the complex relationship between the parameters and dependent variables;Finally,combining the influence of component size and energy consumption value,the optimal decision on the basis of data analysis can be obtained and the remould mode of window decoration components suitable for different orientations of residential buildings in this area is gained.
