Previously, wooden houses did not need additional accessible ventilation in the basement. The material for such construction missed the required amount of air. The presence of cracks on the doors and window frames was filled with fresh air at home, and the chimney folded on clay with sand performed the functions of the hood. Natural ventilation of any building is real in the presence of a difference in pressure and temperature from the outside and inside the building. Therefore, the efficiency of ventilation at lower temperatures is greater.
