As height of new development rises, there is an increase in pressure from the windward side and in eddy flows from the leeward side of a high-rise building. This pressure affects not only neighboring high-rises, but also it has an impact on low-rise existing ones. The purpose of the study is to model wind flows to determine maximum aerodynamic wind effects on multi-storey buildings and their surroundings. It also aims at improving the expression for defining maximum wind load depending on the building height and the distance to it. In this study numerical experiments on modeling the distribution of wind flows in a virtual wind tunnel for an existing low-rise building have been carried out. Based on their results, an increasing coefficient in the expression for determining the wind load depending on the height of a multi-storey building and the distance to it is proposed. The results obtained can be used in determining wind loads during the reconstruction of low-rise buildings and their verification calculations when placing multi-storey and high-rise buildings in existing buildings.
