A common barrier when adopting natural ventilation in buildings located in urban environments
is the potential exposure to external pollutants. Whilst mechanical ventilation systems can
draw air through cleaning filters the driving pressures associated with naturally ventilated
buildings are too low.
|
A strategy suitable for naturally ventilated buildings includes, identifying sources of
pollution surrounding buildings and positioning air inlet devices in a sensible way.
|
The interactive design tool identifies all urban sources of pollution and indicates how different
ventilation approaches will determine the type of pollution control features required within air
inlets. Since size of air inlets in relation to ventilation performance is also an important
issue, design tools are attached that calculate appropriate opening areas.
