The article is devoted to the problem of determining the air flow through cracks in the enclosing structures using numerical methods. Based on the study of the data obtained during the visual inspection, it was found that most of the apartment buildings have significant physical wear, which is mainly characterized by the presence of cracks. Particular attention is paid to the assumptions made for the design scheme. On the basis of the equations of dynamics and continuity, a mathematical model is obtained that allows one to predict the airflow through the crack
