Ventilation On Demand

EastLink's innovative ventilation on demand system has reduced tunnel power usage by nearly 70%, saving approximately 6.2 GWh and 9,000 tonnes of GHG emissions annually. Audible noise from the ventilation stacks has halved.

The new system won EastLink the ITS Australia National Industry Award 2018, and was a factor in GRESB awarding EastLink the top 5-star sustainability rating in 2019.

The power usage chart for the EastLink tunnels shows the nearly 70% reduction in power usage that was achieved when the ventilation on demand system was fully activated in mid March 2018:
