摘　　要：城市街区、建筑单体等不同尺度空间存在跨尺度的性能耦合情况,大尺度空间微气候的异质性将影响建筑性能。研究依托参数化平台的城市天气生成器(UWG)程序,构建面向性能精细表征的微气候分析及能耗计算方法,该方法以短时气象数据为依据,对UWG模型进行精确的优化校准;基于校准后的UWG模型生成局地典型气象年数据(TMY),探讨城市热岛效应对局地室外热舒适度和建筑能耗的影响。研究为城市微气候条件下的性能设计提供科学依据,强调设计师在方案阶段应充分考虑城市热岛效应的重要性,从而精细化地推动城市可持续发展和节能降碳目标的实现。There exist multi-scale performance couplings among different spatial scales such as urban blocks and individual buildings.The heterogeneity of macro-scale microclimates will affect building performance.This study relies on the Urban Weather Generator(UWG)software to construct a calculation method for urban microclimate and energy consumption oriented to best performance characterization.The method uses short-term meteorological data as the basis to accurately optimize and calibrate the UWG model.Based on the calibrated UWG model,local typical meteorological year data(TMY)are generated,which finely characterizes the impact of the urban heat island effect on the outdoor thermal comfort and building energy consumption.It also provides scientific evidence for performance design under urban microclimate conditions,emphasizing the importance of considering UHI during the design phase.This approach could promote more sophisticated sustainable urban development,achieving energy conservation and carbon reduction targets.
