The relevance of the study is determined by the current use of natural ventilation systems for organizing the air regime in modern residential buildings, which, for certain reasons, are not able to provide it uninterruptedly in the annual cycle of operation. The purpose of the study was to consider the factors affecting the efficiency of natural ventilation systems with individual exhaust ducts serving the premises of multi-apartment residential buildings. An analysis of the influence of climatic (mobility and temperature of the outside air) and structural (conditions of actual operation) factors on maintaining the calculated air exchange by these systems is given. The results obtained during the study are presented in analytical and graphical form and allow us to evaluate the efficiency of ventilation systems with natural induction of air movement for some typical combinations of environmental parameters, as well as the use of supply devices and interior doors that were not taken into account at the design stage. As a result, a general conclusion was drawn about the impossibility of ensuring the calculated values of air exchange in residential premises of existing, reconstructed and newly built apartment buildings by means of exclusively natural ventilation and the need to replace it with mechanical and hybrid (natural-mechanical) systems that provide forced air movement and are less dependent on changes in parameters of outdoor environment.
