4 Treasury Place, Melbourne

When Airmaster Automation was engaged directly by Ventia to address an existing zencontrol installation at 4 Treasury Place, they found a system in significant disarray. The building is no ordinary office block. Built in 1911, it is a heritage-listed government landmark in East Melbourne that houses the Melbourne Commonwealth Parliament Offices. The building had approximately nine separate, isolated lighting control networks with over 500 active faults.

Airmaster's scope went well beyond fault rectification. The team unified all island networks into a single seamless lighting control network, replaced wireless routers operating across lighting control segments with hardwired connections to the building's core network, and reconfigured both the BMS and lighting control system to allow full communication between platforms.

The most significant outcome was the integration of the building's lighting and HVAC systems. Motion sensor occupancy data from the zencontrol lighting network now flows directly to the BMS, triggering setback and occupied modes on hundreds of FCU zones. Rather than running on fixed schedules, the HVAC system responds in real time to where people actually are in the building.

The results were substantial. The facilities manager contacted Airmaster directly to report significant energy savings and improved user comfort across the building. The project was completed in September 2024.

4 Treasury Place is a great example of what's possible when an integrator brings both the technical depth and the initiative to think beyond the original brief. Airmaster turned a fragmented, fault-ridden system into a genuinely smart building.
