【摘要】：长期以来,我国建筑节能工作均是通过相对参照建筑的节能率进行评价,而现实生活中并不存在参照建筑,且这种以节能率衡量建筑节能的方式无法实现对建筑节能的总量控制。为了对建筑能耗进行更准确的定量评估,本文以广州地区国家机关办公建筑为研究对象,从建筑全过程节能管理的角度出发,通过三类定额指标:负荷定额指标、系统装机容量定额指标以及累计耗电量定额指标对建筑节能进行总量控制。不同的定额指标对应建筑生命过程的不同阶段,并可通过调整各个阶段的设计因子对建筑节能实施优化设计。本文以能耗调研和能耗模拟两种方法确定了广州市国家机关办公建筑的能耗定额指标,虽然统计样本容量偏少,但结合模拟得出来的成果对工程实践仍具有一定指导意义。具体来说本文的主要研究工作可以分为以下几个部分:首先,本文描述了建筑全过程节能管理的基本概念,在此基础上提出了由负荷定额指标、系统装机容量定额指标以及累计耗电量定额指标组成的能耗定额指标体系,并对这三类指标分别进行了阐述。在明确各定额指标的功能作用后,论文对建立定额指标体系的必要性以及定额指标制定原则进行了详细分析,重点阐述了项目各个阶段各能耗定额指标的控制参数类型及各冲突优化策略;其次,为掌握建筑能耗水平,了解实际用能情况,本文以广州市13栋国家机关办公建筑为调研对象,统计了其在2013年~2015年的总耗电量。经过对原始数据进行稳定性和有效性检查,得到了良好的数据样本,并利用Origin软件对新样本进行了正态性检验。通过统计学分析方法对样本数据进行分析处理后,得出样本的平均值为54.87kWh/(m~2·a),标准差为36.87kWh/(m~2·a),为后文编制定额表提供实际参考依据;在《公共建筑节能设计标准》(GB-50189-2015)的基础上,结合调研结果及前人研究成果,对主要功能房间的空调、照明、设备作息模式进行了调整,并利用DeST软件模拟了四种常见建筑体型的机关办公建筑。通过模拟得出的全年逐时冷负荷,分别计算了不同体型建筑在风机盘管+新风系统和多联机系统两种不同空调系统形式下的各能耗指标值,利用平均值法最终确定广州市国家机关办公建筑的冷负荷定额指标QL为146W/m~2,累计耗冷量定额指标QC为120kWh/m~2,空调系统装机容量定额指标QA为50W/m~2;最后,本文在分析广州市目前的节能技术水平以及经济发展水平的前提条件下,确定了适用于制定广州地区国家机关办公建筑累计耗电量指标的研究方法——定额水平法,并合理设定了新建国家机关办公建筑和既有国家机关办公建筑的定额水平分别为0.3、0.2。结合调研能耗数据和模拟能耗数据,最终得出广州市新建国家机关办公建筑和既有国家机关办公建筑的累计耗电量定额指标分别为82kWh/(m~2·a)、90kWh/(m~2·a)。
[Abstract]:For a long time, the work of building energy saving in our country has been evaluated by relative reference building energy saving rate, but in real life there is no reference building. In order to evaluate the energy consumption of buildings more accurately and quantitatively, this paper takes the office buildings of state organs in Guangzhou as the research object. From the point of view of energy saving management in the whole construction process, through three kinds of quota index: load quota index, The system installed capacity quota index and the accumulative power consumption quota index carry on the total control to the building energy saving. The different quota index corresponds to the different stage of the building life process, The energy consumption quota index of office buildings in Guangzhou is determined by means of energy consumption investigation and energy consumption simulation, although the statistical sample capacity is small. The main research work of this paper can be divided into the following parts: firstly, this paper describes the basic concept of energy saving management in the whole construction process. On this basis, the energy consumption quota index system is put forward, which is composed of load quota index, system installed capacity quota index and accumulative power consumption quota index. After clarifying the function of each quota index, the necessity of establishing quota index system and the principle of establishing quota index are analyzed in detail. The control parameter types and conflict optimization strategies of each energy consumption quota index in each stage of the project are expounded emphatically. Secondly, in order to grasp the energy consumption level of building, to understand the actual energy use situation, The total power consumption of 13 state office buildings in Guangzhou from 2013 to 2015 is calculated. After checking the stability and validity of the original data, a good data sample is obtained. The results show that the average value of the sample is 54.87 kW / m ~ 2 路a / a, and the standard deviation is 36.87 kW / / / m ~ (2) 路a ~ (-1), which provides a practical reference basis for the later work out of the quota table by using the Origin software to test the normality of the new sample, and the statistical analysis method is used to analyze and process the sample data. On the basis of GB-50189-2015), combined with the research results and previous research results, the air conditioning, lighting and equipment working and rest modes of main functional rooms are adjusted. By using DeST software, four kinds of office buildings with common building shapes are simulated. The hourly cooling load is obtained by simulation. The energy consumption index values of different types of buildings under two different types of air conditioning systems, Fan-Coil Unit fresh Air system and Multi-on-line system, are calculated respectively. The average value method is used to determine the cooling load quota QL is 146W / mm2, the accumulative consumption quota QC is 120kWh/ mm2, and the air conditioning system installed capacity quota QA is 50W / mm2; finally, Based on the analysis of the technological level of energy saving and the prerequisite of economic development in Guangzhou, this paper determines the research method of quota level, which is suitable for formulating the accumulative power consumption index of office buildings in Guangzhou. And reasonably set the quota level of new state office building and existing state office building is 0.3 / 0.2.Combined with the energy consumption data and simulated energy consumption data, Finally, it is concluded that the accumulative power consumption quota index of the new and existing state office buildings in Guangzhou is 82 kWh-1 / 2 路a ~ (-1) and 90 kW / / m ~ 2 路a ~ (-1), respectively.
