A new methodology is proposed to couple a meteorological model with a building energy use model. The aim of such a coupling is to improve the boundary conditions of both models with no significant increase in computational time. In the present case, the Canopy Interface Model (CIM) is coupled with CitySim. CitySim provides the geometrical characteristics to CIM, which then calculates a high resolution profile of the meteorological variables. These are in turn used by CitySim to calculate the energy flows in an urban district. We have conducted a series of experiments on the EPFL campus in Lausanne, Switzerland, to show the effectiveness of the coupling strategy. First, measured data from the campus for the year 2015 are used to force CIM and to evaluate its aptitude to reproduce high resolution vertical profiles. Second, we compare the use of local climatic data and data from a meteorological station located outside the urban area, in an evaluation of energy use. In both experiments, we demonstrate the importance of using in building energy software, meteorological variables that account for the urban microclimate. Furthermore, we also show that some building and urban forms are more sensitive to the local environment.
提出了一种将气象模型与建筑能耗模型耦合的新方法。这种耦合的目的是在不显著增加计算时间的情况下改善两个模型的边界条件。在当前案例中，冠层界面模型（CIM）与CitySim耦合。CitySim为CIM提供几何特征，然后CIM计算气象变量的高分辨率剖面。这些剖面进而被CitySim用于计算城市区域的能量流。我们在瑞士洛桑的洛桑联邦理工学院校园进行了一系列实验，以展示耦合策略的有效性。首先，使用2015年校园的实测数据驱动CIM，并评估其再现高分辨率垂直剖面的能力。其次，在能源使用评估中，我们比较了使用当地气候数据和来自市区外气象站的数据。在这两个实验中，我们证明了在建筑能源软件中使用考虑城市微气候的气象变量的重要性。此外，我们还表明，一些建筑和城市形态对当地环境更敏感。
