    Abstract. The main provisions of mathematical modeling of air regime of residential buildings are considered; the solution of this problem on the basis of the theory of hydraulic circuits is also offered. The dependences describing the relationship of pressure losses and airflow rate for individual elements of ventilation systems are given. The formulas making it possible to take into account with higher accuracy the characteristics of fans, supply and exhaust valves, window and door units included in the aerodynamic network of ventilation systems are proposed. The influence of the method of setting the dependence of airflow on the pressure drop on the results of mathematical modeling is evaluated. Examples of calculation schemes and graphs of some ventilation systems, calculation algorithm, and simulation results of air conditions of buildings with due regard for changes in the characteristics of ventilation elements at the operation stage are presented.
    Key words: ventilation, mathematical modeling, pressure loss, air flow rate, resistance characteristics.
