摘要: 通过对西安建筑科技大学雁塔校区自测气象数据与气象局所建台站的实测气象数据进行对比分析,确定实测地与台站之间的城市热岛(UHI)强度;以台站长期观测记录数据为基准,利用"Morphing"变形方法,对建筑所在地的干球温度、相对湿度和太阳辐射等气象参数进行修订,生成UHI效应下的典型气象年(TMY);应用Energy Plus对办公建筑进行模拟,研究UHI对建筑能耗的影响。结果表明,在考虑UHI效应下,修订后的建筑负荷比修订前更接近实测地的建筑负荷。Abstract: This paper compares and analyses the self-measured meteorological data of Yanta campus of Xi’an University of Architecture and Technology and the measured meteorological data of the station established by the Meteorological Bureau,and determines the urban heat island(UHI)intensity between the measured site and the station. Taking the long-term observation data of stations as the benchmark,the“M”deformation method is used to revise the meteorological parameters such as dry bulb temperature,relative humidity and solar radiation at the building site,and generate a Typical Meteorological Year(TMY)under the UHI effect.EnergyPlus is applied to simulate modeled offices to study the influence of UHI on building energy consumption. The results show that the revised TMY building load is closer to the measured building load than the TMY building load when considering the UHI effect.
