초록
Despite the excellency of unsteady flow simulation around urban building forest, Large Eddy Simulation(LES) is still a heavy tool due to computation time bottleneck. This paper introduces a simple wind resourceassessment method by reducing number of LES simulation cases using geometrical symmetry of a buildingcomplex. As a demonstration case, wind resource assessment of Daejeon Government Complex (DGC)consisting of four symmetrical blocks was carried out. It was possible to reduce wind directional simulationsfrom 16 to 3 cases by mirroring transformation using four symmetric axes of the building Also, it wasconfirmed that identification of prevailing wind direction and ventilation pathway within a building complex iscrucial for Building-Integrated Wind Turbine (BIWT) siting.
