...By Location of the Passive Ventilation The passive ventilation system is a type of ventilation that is composed of openings that are mostly located in wet rooms. They are usually connected via vertical ducts to the roof terminals. Warm and moist air is drawn up these duct by the combination of the wind and stack effect. Dry air is then drawn into the system via background ventilators that are located in habitable rooms. A gap should be given at the bottom of the internal doors to allow free passage of air through the system. Therefore, it is important to maximize the air flow by designing the house with openings at different levels. This cans also be done by...
