【摘要】：随着社会生活和住宅建筑的快速发展,人们对于室内舒适度的要求也越来越高,在建筑中充分利用天然光、创造适宜的天然光环境具有相当重要的现实意义。目前在我国的建筑初步设计过程中,对于建筑外窗尺寸的确定并没有确定的方法和公式。由于我国新实施的《建筑采光设计标准》GB50033-2013中对于侧面采光评价标准的修订使得建筑设计中外窗尺寸下限与原有标准的规定有所差别,建筑外窗尺寸的改变必然引起建筑能耗的变化,因此仅以设计经验来确定建筑外窗尺寸具有一定的片面性。现有的建筑光环境以及建筑节能方面的研究大多只是以单一的建筑采光评价指标为基础,并未分析由于采光评价指标的改变会对建筑外窗尺寸以及建筑能耗产生怎样的影响,因此,并不能对建筑性能进行准确评价。基于以上问题,本文的研究主要从以下三个方面展开:首先,利用分别建立沈阳、北京、长沙、广州、昆明这五个城市住宅和办公建筑各个房间的基本模型,得到基础建筑各个房间满足不同侧面采光评价指标的窗宽尺寸下限,并在此基础上分析其变化规律。其次,建立沈阳、北京、长沙、广州、昆明的办公和住宅建筑分别满足不同采光评价指标外窗尺寸下限的基础模型,并模拟其能耗,在此基础上分析不同外窗尺寸和不同采暖空调运行方式对建筑能耗的影响。最后,利用正交试验设计法得到训练数据,建立了住宅建筑外窗尺寸的BP神经网络估算模型,该模型可根据建筑围护结构的尺寸初步估算不同住宅房间满足采光标准的外窗尺寸下限,对设计人员在建筑设计初步阶段确定住宅外窗尺寸可提供一定的参考。
[Abstract]:With the rapid development of social life and residential buildings, people have higher and higher requirements for indoor comfort. It is of great practical significance to make full use of natural light and create suitable natural light environment in architecture. At present, there is no definite method and formula for the determination of the outer window size in the preliminary design of buildings in our country. Due to the revision of the side lighting evaluation standard in the newly implemented GB50033-2013, the lower limit of the dimension of the window in the architectural design is different from that of the original standard. The change of building window size will inevitably lead to the change of building energy consumption, so it is one-sidedness to determine the outer window size only based on the design experience. Most of the existing researches on building light environment and building energy conservation are based on a single building lighting evaluation index, and do not analyze how the change of lighting evaluation index will affect the building outer window size and building energy consumption. Therefore, the performance of the building can not be accurately evaluated. Based on the above problems, the research of this paper is mainly carried out in the following three aspects: firstly, the basic models of each room of residential and office buildings in Shenyang, Beijing, Changsha, Guangzhou and Kunming are established respectively. The lower limit of window width is obtained for each room of the foundation building to meet the evaluation index of different side lighting, and on this basis, the variation law of window width is analyzed. Secondly, the basic models of office and residential buildings in Shenyang, Beijing, Changsha, Guangzhou and Kunming to meet the lower limit of outer window size of different lighting evaluation indexes are established, and their energy consumption is simulated. On this basis, the influence of different outer window size and different heating and air conditioning operation mode on building energy consumption is analyzed. Finally, a BP neural network model for estimating the outer window size of residential buildings is established by using the orthogonal experimental design method to obtain the training data. The model can preliminarily estimate the lower limit of the outer window size of different residential rooms according to the dimensions of the building envelope structure, which can provide a certain reference for the designers to determine the outer window size of the residence in the initial stage of the architectural design.
