未来气候变化下不同屋顶类型的建筑能耗评估

Building Energy Consumption Assessment of Different Roof Types under Future Climate Change

随着未来全球气候变暖,基于典型气象年的气象数据,不能准确反映未来气象条件下的建筑能耗变化。选取北京市典型气象年为基准年数据和IPCC提供的月尺度预测数据,采用"变形"的降尺度方法,得到北京市2050年和2080年的逐时气象数据。使用能耗模拟软件EnergyPlus对北京市三种不同屋顶配置(普通屋顶、冷屋顶和绿化屋顶)的多层住宅和办公建筑、高层住宅和办公建筑进行能耗模拟,定量分析不同屋顶配置和不同建筑类型在未来气候变化下的建筑能耗状况,为设计师提供了新的设计思路在未来气候变化下。

The typical meteorological year of Beijing is selected as the base year data and the monthly scale prediction data provided by IPCC,and the hourly meteorological data of Beijing in 2050 and 2080 are obtained by using the"deformation"downscaling method.The energy consumption simulation software EnergyPlus is used to simulate and quantitatively analyze the energy consumption of multi-storey residential and office,and high-rise residential and office buildings with three different roof configurations(common roof,cold roof and green roof)in Beijing under the climate change.The energy consumption of buildings with different roof configurations,different types of buildings on different floors under the future climate change are obtained.Assessment provides designers with a new design idea under climate change.
