【摘要】：随着社会经济的快速发展,能源问题日益加重,建筑节能已经成为重中之重。考虑呼包鄂地区丰富的太阳能资源,以降低住宅建筑本体能耗为目的,将住宅建筑系统能耗作为研究对象。建立呼包鄂地区典型城市一栋6层住宅建筑模型,利用清华大学开发的De ST软件动态模拟窗户、外墙、窗墙比、屋顶对建筑围护结构的负荷变化,模拟出16个正交试验结果。通过对建筑能耗的模拟分析,研究围护结构形式对建筑能耗的影响变化,分析得出每个因素影响建筑能耗的显著性程度,找出围护结构最佳水平的优化方案。最后建议呼包鄂地区住宅建筑节能要加强保温厚度、控制窗墙比大小、选用传热系数较低的节能窗户从而降低能耗,节约能源。
[Abstract]:With the rapid development of social economy, the energy problem is becoming more and more serious, and building energy saving has become the most important. Considering the abundant solar energy resources in Hubao Hubei area, in order to reduce the energy consumption of residential building body, the energy consumption of residential building system is taken as the research object. A six-story residential building model in Hubao Hubei area is established. The De ST software developed by Tsinghua University is used to dynamically simulate the load changes of windows, exterior walls, window-wall ratios and roofs on the building enclosure structure, and 16 orthogonal test results are simulated. Through the simulation analysis of building energy consumption, the influence of enclosure structure form on building energy consumption is studied, the significance degree of each factor affecting building energy consumption is obtained, and the optimization scheme of the best level of envelope structure is found out. Finally, it is suggested that the energy saving of residential buildings in Hubao Hubei should be strengthened, the ratio of window to wall should be controlled, and the energy saving windows with low heat transfer coefficient should be selected to reduce energy consumption and save energy.
