VENTILATION AND INFILTRATION - AIVC

controlled natural ventilation. Infiltration is that flow of air through cracks, interstices, and unintentional openings due to the pressure of wind and the buoyancy effect caused by dif· ferences between the indoor and outdoor temperatures. Con­ trolled natural ventilation is that which is due to openable windows and doors.
