The Parliament building in Cardiff is adorned with the world’s largest rotating wind cowl. Contained within its aluminium shell is a modulating volume control damper to allow the debating chamber below to breath. Natural daylight is introduced through a suspended inverted mirror cone.
The World Wildlife Foundation is an eco-designed building using the latest natural ventilation strategies. The roof is fitted with four rotating wind cowls that track away from the wind to allow the building to breath. Fresh air is introduced with bespoke inlet louvre turrets at low level.
The roof of the three storey housing and office development is fitted with 79 omni-directional rotating wind cowls that provide both intake and extract air through the same roof terminal via passive heat recovery cassettes mounted in the base of each wind cowl.
Thirty nine rotational ventilators are installed onto the roof of the centre, positioned over each of the three malls. These cowls are designed to rotate into the prevailing wind under speeds as low as 2m/s.
When the hall was full extreme temperature build up occurred with no means of ventilating the heat. Vision installed two windcatchers that alleviate the temperature build up providing a comfortable environment at peak occupancy.
