Monodraught ‘Windcatcher’
Passive stack ventilation system
Windcatcher technology provides natural ventilation without any moving parts. Using compartmentalised vertical vents, fresh air is brought into the room and stale warm air expelled using the natural effects of the wind.
The system works through normal atmospheric properties where warm air rises and decreases the air pressure within a room so that cooler air falls into the room. This is a subtle change in air pressure and it produces only enough airflow to make the room comfortably fresh.
Stale and stagnant air is extracted by the wind blowing onto the wind-ward side of the windcatcher, with the stuffy air going out through the leeward side of the ventilation stack.'
