In order to accurately analyze building energy performance, it is important to take into account the outdoor microclimate. However, this can be challenging when different microclimates affect the same building using existing simulation tools. This study proposes a method to combine a Computational Fluid Dynamics (CFD) tool for microclimate simulation and a Building Energy Simulation (BES) tool for energy performance analysis within the Grasshopper interface. The method was tested in a case study involving a courtyard, which is a well-known example of microclimate affecting buildings. Results showed that considering the microclimate can significantly alter simulation results, reaching differences of 11% in energy transmitted through exterior wall, and 18% through the windows, the most affected elements, in some rooms. The total energy load of the room generally increased in the upper level of the house and was reduced in the lower level. This study is particularly relevant for practitioners in Spain, where the BES software used is required by the government for energy certification of buildings. |
