摘　　要：利用三维微气候软件ENVI-met对城市微气候进行模拟,然后提取建筑周围的空气温度、空气湿度、建筑表面风速和风压分布输入到建筑能耗模拟工具EnergyPlus中作为外部气象边界条件,从而实现定量预测和评价城市微气候对建筑能耗的影响。案例研究结果显示,所提出的协同模拟方法能够定量评价不同微气候要素对建筑显热冷负荷、潜热冷负荷以及不同途径建筑得热量的影响,模拟结果可为街(住)区规划和建筑设计提供科学依据。Using the urban microclimate model ENVI-met to simulate urban microclimate, taking microclimate context around a building, such air temperature, air humidity, wind speed and pressure on the surface of building as the outside boundary condition of the EnergyPlus model for simulating building energy consumption, the quantitative forecast was implemented and the effect of urban microclimate on building energy consumption was evaluated. The results of a case study show that the proposed co-simulation method can quantitatively evaluate the effects of different microclimatic factors on building cooling loads （e.g. sensible cooling load, latent cooling load, and the heat gains of buildings）, and can be useful for the optimal designs of urban blocks and buildings.
