气候变化对我国不同气候区建筑供热制冷能耗的影响
文章摘要:本文选取五个建筑气候区代表城市,分析探讨了气候变化对办公建筑供热制冷能耗、建筑节能设计气象参数的影响,预估了未来中等排放情景下50~100年的供热制冷能耗。结果表明:各气候区建筑供热能耗均受温度影响,制冷能耗在哈尔滨受温度影响,在天津、上海和广州受温度和湿度的共同影响,夏季空调系统应充分考虑除湿功能;在气候变暖的背景下,建筑节能气象参数发生了明显变化,不同气候区的变化幅度明显不同,且冬季影响大于夏季,考虑气候变暖北方地区供热有3%~5%的节能... 展开
Abstract:This study investigated the impacts of climate change on heating and cooling energy consumption,and outdoor meteorological parameters for building energy-saving design in different cities representing major climatic zones in China. In addition,the building energy demand for heating and cooling in the future 50-100 years for the medium-emission scenario were predicted. The results showed that heating energy consumption is dominantly ... 展开
