Australian hyperscale data center quadruples energy savings targets

Reducing environmental impact and advancing carbon-neutrality goals were only part of the challenge. The team also needed to improve operational efficiency and energy performance across hyperscale data centers in the Asia-Pacific region, where sustained cooling demand and varied operating conditions make optimization more complex. Plant data was split across Johnson Controls and third-party systems, limiting visibility into chiller efficiency, real operating patterns and emerging issues within mission-critical HVAC infrastructure. A more integrated digital approach was required to consolidate data, identify inefficiencies faster and maintain stable, high-density operations.

To address this, the provider consolidated equipment data into an integrated digital platform.

OpenBlue Central Utility Plant Optimization supported this approach by enabling the team to:

• Compare chiller efficiency under real load conditions
• Monitor COP trends across two data halls
• Detect deviations requiring immediate attention
• Prioritize maintenance based on plant performance and trend analysis

Targeted dashboards helped operators quickly identify high priority events.

The first phase of work delivered clear improvements that gave the team clearer insight into plant performance:

• Achieved 4x the internal energy-savings target
• More than 1 million kWh of annualized energy savings
• Over $70k in cost savings in eight months
• Improved COP visibility across the mechanical plant
• Earlier detection of efficiency drift in chillers and auxiliary systems

These outcomes help the provider improve efficiency while maintaining resilient, mission-critical operations.
