【摘要】：气候变暖已对建筑全生命周期的运行状况产生了不可忽略的影响,准确评估气候变化下的建筑能耗对建筑方案设计和既有建筑的节能改造具有重要意义。进行气候变化下建筑能耗的精确预测,必须拥有未来的逐时气象数据。以寒冷地区北京和夏热冬暖地区广州为研究对象,将挑选的两个城市典型气象年为基线气候,结合全球模式下的预测气象数据,应用变形法修正TMY的气象参数,得到直至本世纪末的10个节点年逐时气象文件,并进行了全年能耗模拟,预估了两个城市的办公建筑在气候变化下建筑能耗的变化趋势。结果表明:在两种预测排放情景下,干球温度、含湿量和太阳辐射均呈增加趋势;北京采暖能耗显著降低、制冷能耗增加,总能耗减少,广州采暖能耗降低、制冷能耗显著增加,总能耗增加。
[Abstract]:Climate warming has had a significant impact on the whole life cycle of buildings, and it is of great significance to accurately evaluate the energy consumption of buildings under climate change for the design of building schemes and the energy-saving transformation of existing buildings.Accurate prediction of building energy consumption under climate change requires future hourly meteorological data.Taking Beijing in cold region and Guangzhou in hot summer and warm winter as the research object, the typical meteorological year of two cities was selected as the baseline climate, and the meteorological parameters of TMY were modified by the deformation method combined with the forecast meteorological data under the global model.The annual hourly meteorological documents of 10 nodes up to the end of this century are obtained, and the energy consumption simulation for the whole year is carried out, and the change trend of building energy consumption of office buildings in two cities under the climate change is estimated.The results show that the dry ball temperature, moisture content and solar radiation are all increasing in the two predicted emission scenarios, and the heating energy consumption in Beijing decreases significantly, the refrigeration energy consumption increases, the total energy consumption decreases, and the heating energy consumption in Guangzhou decreases.Refrigeration energy consumption increased significantly, the total energy consumption increased.
