Machine learning optimization of a 5,600 TR chiller plant serving a 24/7 hotel and entertainment complex — delivering 12.3% efficiency gains and over $105,000 in verified annual savings.
The Challenge
Crown Casino Melbourne operates one of Australia's largest integrated entertainment complexes — a 658-room hotel with continuous 24/7 cooling demand that places extreme and variable load on the central HVAC plant. The facility's 5,600 TR chiller plant was controlled by a Honeywell BMS using fixed sequence-of-operations logic.
Unlike a standard commercial office, the casino's load profile is driven by occupancy patterns, event scheduling, and ambient conditions that shift dramatically across hours of the day. Fixed set-point controls could not adapt to these dynamics, resulting in inefficient chiller staging, excess energy consumption, and avoidable carbon emissions.
The challenge was to optimize a complex, always-on facility where operational disruption of any kind was unacceptable — and where energy efficiency gains had to be proven through independent measurement and verification.

The Exergenics Approach
Exergenics deployed its AI platform to learn the facility's complex load patterns and deliver continuous, adaptive optimization signals — integrated directly into the existing Honeywell BMS with zero operational disruption to the 24/7 entertainment operations.
Exergenics ingested historical BMS, energy meter, and occupancy data to train machine learning models on the facility's unique demand patterns — capturing event-driven load spikes, overnight base load, and ambient temperature correlations.
The platform continuously computes optimal chiller staging, condenser water set-points, and cooling tower fan speeds to minimize kWh consumed per ton of cooling delivered — responding dynamically to actual load rather than fixed schedules.
Control signals were integrated directly into the Honeywell BMS in June 2022 with zero operational downtime — a critical requirement for a 24/7 facility. Savings were subsequently verified through a full IPMVP Option B measurement and verification process.
Verified Results
All savings were independently verified using IPMVP Option B methodology — the most rigorous measurement and verification standard, requiring metered data from the optimized systems over a full 12-month performance period.
