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.
These unique ventilation towers are designed to allow passive air extract over a 360 degree range and will ventilate regardless of weather conditions through the innovative circular chimney constructed from stretched polycarbonate panels.
The building is naturally ventilated by seven roof towers providing passive ventilation. Air passed through the building into open atriums in the centre of the building.
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 library and civic offices are fitted with five bespoke fixed ventilation turrets fitted with internal rotating drums, one for extra and one for inlet that track the wind direction and automatically move to into the wind to provide optimum natural ventilation.
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.
A bespoke design to provide an architectural statement for the surrounding areas and to provide maximum daylight through the double glazed units on the conical top.
