【摘要】：当今时代,日益严峻的全球资源短缺危机,控制与节约能耗越来越受到关注。我国经济蓬勃发展与城市高速建设,增加了建筑能耗在各能源总消耗中的比重。当前建筑工作者对办公建筑低能耗设计的研究较为深入,着眼于新技术、新能源、新材料等方面,均获得较为显著的研究成果。但在目前研究中,针对严寒地区既有办公建筑的低能耗设计分析与研究较少。本文即是在这样的背景下,研究了严寒地区办公建筑形态参数与能耗间的定量关系。通过对既有办公建筑的抽样调查,建立严寒地区多层办公建筑典型形态数据参数组,并以此为依据作为模拟试验模型建立依据。通过对各形态要素的模拟实验,得出其与能耗的定量关系,并总结出最佳形态设计参数组及各参数与能耗的多元回归模型,以探究如何在建筑设计阶段更为有效地控制建筑能耗。文章首先分析低能耗办公建筑设计现状与严寒地区办公建筑形态设计特征,提取办公建筑能耗相关形态设计影响参数,确立研究方法与框架。选择严寒地区代表城市哈尔滨进行实地调研,采集形态参数并进行值域分析,得到形态设计参数典型数据库,建立典型模型形态数据组。之后本文采用建筑全能耗模拟软件energyplus,分别以建筑平面形状与朝向、建筑体型设计参数,包括建筑总开间及进深长度和建筑高度,以及建筑各朝向窗墙比为变量,以调研所得典型形态参数组为输入数据组,进行能耗模拟实验。运用统计分析方法,对所得相应数据进行相关度分析及回归拟合,得出各形态设计要素与能耗影响程度及能耗随各要素的变化趋势。并得到常用设计参数下形态参数与能耗的定量关系式及最佳建筑形态设计参数组,在低能耗办公建筑形态设计方案阶段有较为直接的指导意义。最后,对已有模拟数据组进行多元线性回归分析,得到总开间长度、总进深长度、建筑高度及各向窗墙比与建筑能耗的多元回归模型和单层建筑平面面积、建筑长宽比、建筑高度及各向窗墙比与建筑能耗的多元回归模型,并进行敏感度分析,定量各形态因素与能耗的作用关系,优化低能耗办公建筑设计流程。研究严寒地区办公建筑形态参数与能耗间的定量关系,能够在建筑设计阶段有效控制建筑能耗,有利于低能耗设计工作的进行。在设计中通过回归模型及最佳形态参数组的应用可快速高效的比对建筑能耗,快速判断寒地多层办公建筑节能效果,并及时修改形态设计数据,以得到最佳设计结果。
[Abstract]:Nowadays, more and more attention has been paid to controlling and saving energy consumption because of the increasingly severe crisis of global resource shortage. China's booming economy and high-speed urban construction have increased the proportion of building energy consumption in the total energy consumption. At present, the architects' research on low energy consumption design of office building is more in-depth, focusing on new technology, new energy, new materials and other aspects, has obtained more remarkable research results. However, in the present research, the low energy consumption design analysis and research of the existing office buildings in the severe cold area are few. In this paper, the quantitative relationship between the shape parameters of office buildings and energy consumption is studied. Based on the sampling investigation of existing office buildings, the data set of typical forms of multi-storey office buildings in severe cold area is set up, which is used as the basis for the establishment of simulation test model. Through the simulation experiment of each form element, the quantitative relation between each form factor and energy consumption is obtained, and the optimum shape design parameter group and the multiple regression model between each parameter and energy consumption are summarized. In order to explore how to control building energy consumption more effectively in the architectural design phase. Firstly, this paper analyzes the present situation of low energy consumption office building design and the characteristics of office building form design in severe cold area, extracts the influence parameters of office building energy consumption related form design, and establishes the research method and frame. The representative city of Harbin in severe cold area was selected for field investigation, morphological parameters were collected and range analysis was carried out, the typical database of morphological design parameters was obtained, and the morphological data set of typical models was set up. After that, the whole energy consumption simulation software energyplus, is used to take the shape and orientation of the building, the design parameters of the building shape, including the total length and depth of the building, the height of the building, and the ratio of each facing window to the wall of the building as variables. The energy consumption simulation experiment was carried out with the typical morphological parameter group as input data group. By using the statistical analysis method, the correlation analysis and regression fitting are carried out to get the influence degree of each shape design factor and energy consumption, and the trend of energy consumption change with each factor. The quantitative relationship between shape parameter and energy consumption under common design parameters and the optimum design parameters group of building form are obtained, which has direct guiding significance in the phase of form design scheme of low energy consumption office building. Finally, the multiple linear regression analysis of the existing simulated data sets is carried out, and the multiple regression models of the total open space length, the total depth length, the building height and the ratio of each window to wall and the building energy consumption are obtained, and the single floor area and the ratio of building length to width are obtained. The multiple regression model of building height, ratio of window to wall and building energy consumption is presented. Sensitivity analysis is carried out to quantify the relationship between energy consumption and shape factors, and the design process of low energy consumption office buildings is optimized. To study the quantitative relationship between the shape parameters and energy consumption of office buildings in severe cold areas can effectively control the energy consumption of buildings in the stage of building design, which is beneficial to the design of low energy consumption. The application of regression model and optimum shape parameter group in the design can quickly and efficiently compare the energy consumption of buildings, quickly judge the energy saving effect of multi-storey office buildings in cold areas, and modify the shape design data in time to obtain the best design results.
