【摘要】：随着经济的发展，公共建筑能耗所占比例与日俱增，降低公共建筑能耗迫在眉睫。如何有效降低公共建筑能耗，提高能源使用效率是我国目前建筑节能工作的重点。我国于2005年已颁布实施《公共建筑节能设计标准》，，在建筑设计初期严格把关建筑的节能设计，包括围护结构、空调系统等，从源头上控制了新建公共建筑的能耗。而由于没有《公共建筑节能设计标准》的要求，对2005年之前的既有公共建筑能耗较高由此造成的能源浪费不容忽视，对既有公共建筑的节能改造势在必行。目前我国仍没有一部针对既有公共建筑节能的标准或法规，因此，研究既有公共建筑的节能改造具有重要意义。与新建建筑不同，既有公共建筑节能改造涉及因素较多，为避免节能改造的盲目性，应在实施节能改造前充分了解建筑的能耗状况，明确能耗的构成及影响因素。基于这一认识，本文以公共建筑为研究对象，首先采用模拟计算方法，分析建筑能耗构成，进而结合建筑实际情况，针对建筑能耗影响较大的因素提出节能措施。再利用模拟计算方法，预先分析实施改造后的节能潜力，力求在实施节能改造前便能够对改造方案、改造效益等进行预判，做到“有的放矢”，保证节能改造方案的合理性和预期的效应。依据上述的研究思路，本文选择广州某图书馆为实例，运用模拟软件IES（VE）建立了该图书馆能耗模拟模型，然后通过现场测试检验能耗模型的合理性，以此作为深入分析建筑能耗的基础。在此基础上，研究影响该建筑能耗构成的主要因素，结合建筑实际情况和实施改造的可能性，提出了基于网络运行控制与运行管理的改造方案，以有效降低中央空调系统能耗，针对改造方案再次利用模拟软件进行了节能潜力分析。模拟分析结果表明采用该方案可以获得较好的节能改造效益，以分析为依据，实施了节能改造方案，经过改造后的测试，实际节能率达14%，与软件模拟计算结果较为吻合。研究表明，在实施建筑节能改造前，通过软件模拟方法认真分析和评估建筑能耗并提出有针对性的改造方案是一种科学客观的方法。
[Abstract]:With the development of economy, the proportion of energy consumption in public buildings is increasing day by day, so it is urgent to reduce the energy consumption of public buildings. Improving energy use efficiency is the focus of building energy conservation in our country. In 2005, our country issued and implemented "Standard for Energy Saving Design of Public buildings". In the early stage of building design, we strictly controlled the energy saving design of buildings, including enclosure structure, air conditioning system, etc. The energy consumption of newly built public buildings has been controlled from the source. However, since there is no requirement of energy conservation design standard for public buildings, the energy waste caused by the high energy consumption of existing public buildings before 2005 cannot be ignored. It is imperative to retrofit the existing public buildings. At present, there is still no standard or regulation for the energy conservation of existing public buildings in our country. Therefore, it is of great significance to study the energy-saving transformation of existing public buildings. Different from the newly built buildings, there are many factors involved in the energy-saving transformation of existing public buildings. In order to avoid the blindness of energy-saving renovation, the energy consumption of the buildings should be fully understood before the implementation of the energy-saving reconstruction. Based on this understanding, this paper takes the public buildings as the research object. Firstly, by using the simulation calculation method, the composition of the building energy consumption is analyzed, and then the actual situation of the building is combined. The energy-saving measures are put forward in view of the factors which have a great influence on building energy consumption. The energy-saving potential after implementation of the retrofit is analyzed in advance by using the simulation calculation method, and the retrofit scheme and benefit can be forecasted before the energy-saving retrofit is carried out. To achieve a "targeted", to ensure the rationality of energy saving transformation and expected effects. According to the above research ideas, this paper chooses a library in Guangzhou as an example, establishes the energy consumption simulation model of the library by using the simulation software IESVEV, and then tests the rationality of the energy consumption model through field tests. Based on the analysis of building energy consumption, the main factors influencing the building energy consumption are studied, and the possibility of building reconstruction is combined with the actual situation of the building. The transformation scheme based on network operation control and operation management is put forward in order to effectively reduce the energy consumption of central air conditioning system. The energy saving potential is analyzed by using simulation software again. The result of simulation analysis shows that the scheme can obtain better benefit of energy saving transformation. Based on the analysis, the energy saving reform scheme is implemented and tested after the transformation. The actual energy saving rate is up to 14%, which is in good agreement with the result of software simulation. The research shows that it is a scientific and objective method to analyze and evaluate the building energy consumption carefully and put forward a targeted reconstruction plan by software simulation before the implementation of building energy saving transformation.
