Wind Driven Ventilation
Wind
Driven Ventilation or Roof Mounted Ventilation design in buildings provides
ventilation to occupants using the least amount of resources. Mechanical
ventilation drawbacks include the use of equipment that is high in embodied
energy and the consumption of energy during operation. By utilising the
design of the building, Wind Driven Ventilation takes advantage of the natural
passage of air without the need for high energy consuming equipment. Windcatchers
are able to aid Wind Driven Ventilation by directing air in and out of buildings.
Control Dampers
The control dampers in the base of the system would be linked to a BMS system, or can be by manual control or be controlled by carbon dioxide humidity or temperature sensors. These would be linked to the motorised damper to control the rate of ventilation depending upon the time of year and weather conditions. Diffusers are used at ceiling level.
