Wind Catcher
Device to enhance natural ventilation by harnessing wind and passive stack effect.
Stack with weatherproof louvres and an internal divider allowing fresh air intake from any direction and exhaust of stale air in the opposite half of the wind catcher by natural means.
Fins at the vertical edges to catch more wind.
Regulation of fresh air intake by motorized dampers and sensors for internal temperature, CO2, wind movement and humidity under the Building Management System or manual control.
Noise control with acoustic lining insider the stack.
Benefits
Low carbon means to enhance ventilation.
Estimated to increase local air speed by 25% and improve natural ventilation potential for areas furthest away from windows.
Incoming air by natural means relatively free from contamination or traffic pollution carried down from roof to the internal spaces.
Noise reduction of 15dB or more, compared to using an open window for natural ventilation.
