【摘要】：根据目前严峻的能源形势,我国要实现可持续发展,必须实施节能减排。现阶段,在我国社会总能耗中,建筑能耗占比较高,约为26.7%,同时,随着“十三五”规划的战略实施,城乡一体化逐渐形成,商业经济不断发展,我国商务办公建筑面积及能耗均呈快速增长趋势,商务办公建筑能耗所占的份额也逐渐增大。在实现我国节能减排目标的过程中,要把降低商务办公建筑能耗作为重点,而完善的商务办公建筑能耗限额标准是实现建筑节能减排的有效途径。自2015年7月开始,我们在山东省17个设市区开展了商务办公建筑能耗调研和统计工作,采用抽样调查的方法,共调研商务办公建筑212栋。调研的内容主要包括建筑物的基本信息、建筑使用功能和运行方式、建筑能耗和相关费用支出等,同时,为了保证数据的全面准确性,进行调研复核。以山东省城市C为例,将调研结果进行详细介绍。本文对建筑能耗模拟软件EnergyPlus、DeST、TRNSYS、DOE-2进行详细对比和研究,最终采用以动态能耗分析法为核心的DeST-c软件对商务办公建筑能耗进行模拟,建立标准建筑模型,输入气象参数、围护结构、空调系统及其他能耗系统等基本条件,进行模拟运算,导出并分析模拟结果。建筑总能耗为80.97万kWh/a,电耗占总能耗的92.50%,空调能耗、照明能耗分别占建筑总电耗的34.20%、33.71%。在统计定额的编制方法中,定额水平法与平均值法、二次平均法、回归分析法相比,能够更加真实地反映实际用能水平,因此,采用定额水平法来确定统计定额,城市C空调供暖商务办公建筑能耗约束性指标值102.98 kWh/(m2·a),建筑能耗先进性指标值为60.70 kWh/(m2·a);城市C市政热力或锅炉供暖商务办公建筑能耗约束性指标值为85.07 kWh/(m2·a),建筑能耗先进性指标值为55.86kWh/(m2·a),供暖能耗约束性指标值10.20kgce/(m2·a),供暖能耗先进性指标值为6.30 kgce/(m2·a)。依据国家相关法律法规、国家标准、行业标准、地方标准,并符合公平性、合理性、时效性、科学性等原则,将技术定额与统计定额进行相互参照,即对运用DeST-c模拟的结果与调研结果进行分析比较,确定山东省各地市商务办公建筑能耗限额标准的取值。再根据建筑的实际使用情况,进一步修正建筑能耗限额指标。本文将建筑物的碳排放划分为物化阶段、运营维护阶段以及拆除回收阶段三个阶段的碳排放,运营维护阶段的碳排放占的份额较大,大约为60%~80%。在研究碳排放计算方法方面,碳排放系数具有很强的权威性以及可操作性。采用碳排放系数法得到山东省某商务办公建筑运营维护阶段的碳排放量为4.14?410 tCO2,估算出该商务办公建筑在整个生命周期内总的碳排放量为5.175?410 tCO2。
[Abstract]:According to the current severe energy situation, in order to achieve sustainable development, we must implement energy saving and emission reduction. At this stage, building energy consumption is relatively high, about 26.7, and at the same time. With the strategic implementation of the 13th Five-Year Plan, the integration of urban and rural areas is gradually formed, the commercial economy continues to develop, and the space and energy consumption of commercial office buildings in China are increasing rapidly. The share of energy consumption of commercial office buildings is also gradually increasing. In the process of achieving the goal of energy saving and emission reduction in our country, we should focus on reducing the energy consumption of commercial office buildings. And the consummate commercial office building energy consumption quota standard is the effective way to realize the building energy saving and emission reduction. Since July 2015. We have carried out investigation and statistics of energy consumption of commercial office buildings in 17 urban areas of Shandong Province, and adopted the method of sampling survey. A total of 212 commercial office buildings are investigated. The contents of the investigation mainly include the basic information of the building, building use function and operation mode, building energy consumption and related expenses, and so on. In order to ensure the accuracy of the data, the investigation and review. Taking City C of Shandong Province as an example, the results of the survey are introduced in detail. In this paper, the energy consumption simulation software EnergyPlusDeST is introduced in detail. TRNSYSX DOE-2 is compared and studied in detail. Finally, the DeST-c software, which is based on dynamic energy consumption analysis method, is used to simulate the energy consumption of commercial office buildings and establish the standard building model. The basic conditions such as meteorological parameters, enclosure structure, air conditioning system and other energy consumption systems are input, and the simulation results are derived and analyzed. The total building energy consumption is 809,700 kWh/a. Electricity consumption accounts for 92.50% of total energy consumption, air conditioning energy consumption and lighting energy consumption account for 34.20% of the total building energy consumption respectively. Compared with the quadratic average method and the regression analysis method, it can reflect the actual energy level more truthfully. Therefore, the statistical quota is determined by the quota level method. The binding index value of energy consumption of commercial office buildings with C air conditioning is 102.98 kWh/(m2 路a, and the advanced value of building energy consumption is 60.70 kWh/(m2 路a ~ (-1); The binding index value of energy consumption of city C municipal heating or boiler heating commercial office building is 85.07 kWh/(m2 路a). The advanced index value of building energy consumption is 55.86 KW / / m ~ 2 路a ~ (2), and the binding index value of heating energy consumption is 10.20 kg / m ~ 2 路a). The advanced index value of heating energy consumption is 6.30 kgce/(m2 路a. According to the relevant national laws and regulations, national standards, industry standards, local standards, and in line with fairness, rationality, timeliness. Scientific and other principles, the technical quota and statistical quota cross-reference, that is, the use of DeST-c simulation results and research results are analyzed and compared. Determine the value of the energy consumption quota standard of commercial office buildings in Shandong Province. Then according to the actual use of the building, further modify the building energy consumption quota index. This paper divides the carbon emissions of buildings into physical and chemical stage. The carbon emissions of the three stages of operation and maintenance and demolition and recovery are larger than those of the operation and maintenance, about 60,80. in the research of carbon emission calculation method. Carbon emission coefficient has strong authority and maneuverability. By using carbon emission coefficient method, the carbon emission of a commercial office building in Shandong Province is 4.14? Estimated total carbon emissions over the entire life cycle of the commercial office building at 5.175? 410 tCO2.
