Netball Central, Sydney Olympic Park’s state of the art netball complex, is using a natural ventilation solution to deliver precise, energy efficient control over indoor air quality and temperature at the centre.
The environmental ventilation system constantly monitors a range of indoor air quality parameters, including carbon dioxide (CO2), temperature and humidity to maintain a comfortable environment for teams and spectators.
If the air quality exceeds any of the pre-defined environment set-point limits the ventilation system triggers the automatic opening of high and low level louvres to provide ventilation or cooling.
In normal operation, the principle of thermal stacking is used with warm stale air being vented through the high level vents, which has the effect of drawing cooler and fresher replacement air into the building via the low level louvres.
10 dedicated SE Controls PSUs were installed as part of the system, which ensure each louvre responds precisely to the signals received and provides the correct level of ventilation.
The system is also configured to provide night purge cooling at the end of each day, which not only helps reduce the internal temperature, but by fully opening the vents it also ensures that stratified air is removed along with any airborne pollutants that have built up during the day.
