【摘要】：在我国,建筑总能耗在社会能耗中所占的比例已达到近三分之一,建筑业造成的大量能源消耗和二氧化碳排放已成为无法忽视的问题,实现建筑行业的节能减排已经势在必行。其中住宅建筑用能巨大,减少居住建筑能耗对我国的建筑节能工作的意义重大。本文选取地处寒冷地区的山东省济宁市某高层住宅建筑为研究对象,尝试通过对建筑进行节能改造的方式改善建筑的热工性能,进而实现减少建筑能耗的效果。通过实地调研获取建筑的实际结构参数和部分能耗数据,运用DesignBuilder能耗模拟软件建立建筑基础模型,模拟计算并分析其运行能耗,深入分析该建筑实际存在的能耗问题。分别选取我国现行的建筑节能设计标准和德国被动式房屋节能设计规划标准,结合研究建筑的实际情况,设计合适的节能改造措施及方案,并模拟计算经过节能改造后的建筑能耗,分析改造方案的节能效果。最后从节能性和经济性两个方面综合分析评估以被动式房屋为标准的节能改造方案现实可行性和长远经济效益。模拟结果表明,运用基于我国现行65%节能标准的节能改造方案对建筑进行改造后,建筑总运行能耗降低了 52.7%,其中采暖能耗降低了 66.8%,空调制冷能耗降低了 1.7%,全年运行能耗共减少了 767846 kWh。以被动式房屋为标准对建筑进行改造后,建筑总运行能耗降低了 78.9%,其中采暖能耗降低了 96%,制冷能耗降低了 8.7%,全年运行能耗共减少1147957 kWh,该节能改造方案静态投资回收期为19年,该建筑剩余的24年使用寿命周期为收益期,在节能效果和经济性两个方面都具有现实可行性。本课题首次基于被动式房屋节能标准,以我国寒冷地区既有高层住宅建筑为研究对象运用DesignBuilder建筑能耗模拟软件进行节能改造研究,为此类住宅建筑的节能改造提供了可以参考的案例。
[Abstract]:In China, the proportion of total building energy consumption in the social energy consumption has reached nearly 1/3. The energy consumption and carbon dioxide emissions caused by the construction industry have become a problem that can not be ignored. It is imperative to realize energy saving and emission reduction in the construction industry. The energy consumption of residential buildings is huge, and it is of great significance to reduce the energy consumption of residential buildings in our country. In this paper, a high-rise residential building in Jining City, Shandong Province, is chosen as the research object, and the thermal performance of the building is improved by the way of energy saving transformation, and the effect of reducing building energy consumption is realized. The actual structure parameters and partial energy consumption data of the building were obtained by field investigation. The building foundation model was established by using DesignBuilder energy consumption simulation software, and its running energy consumption was simulated and analyzed, and the actual energy consumption problem of the building was deeply analyzed. Select the current building energy saving design standard of our country and passive house energy saving design planning standard of Germany separately, combine the actual situation of the research building, design the suitable energy saving reform measure and plan, The energy consumption of the building after energy-saving reconstruction is simulated and calculated, and the energy-saving effect of the retrofit scheme is analyzed. Finally, the feasibility and long-term economic benefit of the energy-saving reconstruction scheme based on passive housing are analyzed and evaluated comprehensively from the aspects of energy saving and economy. The simulation results show that the energy saving reconstruction scheme based on the present 65% energy saving standard of our country is used to reconstruct the building. The total operating energy consumption of the building has been reduced by 52.7 percent, in which heating energy consumption has been reduced by 66.8 percent, air conditioning and refrigeration energy consumption has been reduced by 1.7kWhs, and the annual operation energy consumption has been reduced by 767846 kWhs. After the building has been renovated according to the standard of passive housing, The total operating energy consumption of the building has been reduced by 78.9 percent, of which heating energy consumption has been reduced by 96, refrigeration energy consumption has been reduced by 8.7 percent, and the annual operating energy consumption has been reduced by a total of 1147957 kWhs.The static investment payback period of the energy-saving renovation scheme is 19 years. The remaining 24-year life cycle of the building is a profit period, which is feasible in both energy saving and economy aspects. For the first time, based on the passive building energy saving standard, this paper takes the existing high-rise residential buildings in cold regions of our country as the research object and uses the DesignBuilder building energy consumption simulation software to carry on the energy saving transformation research. It provides a reference case for the energy saving reconstruction of this kind of residential building.
