Australian Facility and Infrastructure Group is proud to announce that Brookfield Place Tower B in Brisbane has achieved a NABERS Energy rating of 5.5 stars - the highest ever recorded for this asset - in the first year of Our integrated facilities management contract.

How We Did It

The improvement from 4.5 to 5.5 stars was achieved through a systematic program of BMS optimisation, operational scheduling refinement, and targeted equipment upgrades - not through capital replacement of major plant.

  • -BMS setpoint optimisation across 847 zones
  • -Chiller sequencing rescheduled around true occupancy patterns
  • -After-hours HVAC purge program redesigned
  • -18% reduction in total energy consumption vs. base year

What This Means for Tenants

The 5.5-star rating reduces the building's Scope 1 and 2 carbon emissions by approximately 840 tonnes CO₂e annually compared to the 4.5-star baseline - a significant contribution to tenant sustainability reporting and NABERS for Tenancy ratings.
