description: The aim of the study is to identify the influence of the wind backup zone and the resulting overpressure on the roof of a low-rise building on the relative position of buildings and the ratio of their heights and their impact on the functioning of natural ventilation in low-rise buildings. Tasks solved in the course of the study: 1. Collection and analysis of data from regulatory and technical documents, as well as scientific works related to wind impact on buildings; 2. Determination of the influence of the location of a high-rise and low-rise building on the functioning of natural ventilation in the latter based on CFD analysis; 3. Formulation of general recommendations for improving the analysis of the operation of natural ventilation systems. As a result of CFD modeling of wind interaction on buildings, it was concluded that the relative position and geometric characteristics of buildings affect the functioning of the natural ventilation system. With comparable heights of buildings, their relative position relative to each other does not matter, because with wind action, a rarefaction zone is always formed in the area of the roof of a low-rise building, which leads to an improvement in the operation of natural ventilation. With a greater height difference, the relative position of buildings begins to have an impact on the amount of overpressure.
