Quantitative assessment of the conservative addition transfer by filtration flow through the wall

Effect of air filtration on the temperature and humidity conditions of building structures is significant. This explains the great attention which is paid to the question of air filtering through the building envelope. In the air permeable building envelopes heat flow is carried out including by air filtration. Filtering transfer of conservative addition is comparable with heat transfer by thermal conduction. A method for calculating the heat flow by filtering heat transfer was proposed. Calculation examples for lightweight building envelope were given.
