Recently, various building integrated wind power (BIWP) systems have been developed to produce energy by wind power generators installed in buildings. A BIWP does not require a support to position the wind turbine at the required installation height, and it has the advantage of high energy efficiency because the energy produced by the turbine can be used directly within the building, rather than being sent a far distance. In this study, a computational fluid dynamics (CFD) analysis was conducted to examine the wind speed variations occurring due to changes in the building corner morphology, with the goal of using these changes to increase the wind speed and improve the power generation efficiency of a wind turbine installed between two buildings. Round building corners increased the wind velocity by 2–4%, whereas corner cuts increased it by up to 1.5%, when compared to the basic rectangular corner. These shape changes were more advantageous with shorter distances between the buildings.
