Provision of optimal microclimate and determination of the residential building energy saving class dictates the necessity of correctly evaluating the amount of the incoming ambient air in condition of natural ventilation, which should be done at the stage of planning. At estimating the amount of air, the required volumes of air must be taken into account to provide the normative ventilation rate in residential premises and the infiltration factor which depends on the pressure distribution. The authors demonstrate the results of the calculation of outdoor air amount entering the building in accordance with the regulatory documents SP50.13330-12, SP 54. 13330-16, SP 23-1001-2004. Results of the natural measuring of air permeability of the enclosing structures are submitted according to the state standard GOST 31167-2009. The influence of the air permeability value of enclosing structures on the increase of specific energy consumption on heating and ventilation of the building is demonstrated.
