Prestigious London Financial Centre uncovers 15% energy savings and cuts 30 metric tons of CO₂

Prestigious financial centre

Financial centre enhances operational efficiency with AI‑enabled remote chiller diagnostics

A prestigious financial centre in London sought to improve energy efficiency and reduce operating costs across its busy, mission‑critical site. By deploying OpenBlue Services with continuous remote monitoring and AI‑powered diagnostics, the organisation gained deeper visibility into chiller performance and uncovered opportunities for measurable efficiency improvements

Impact Highlights

OpenBlue Services identified a 15% energy-saving opportunity

12–15% more efficient chiller operations

More than 30 metric tons of CO₂ emissions reduced annually

Ensuring seven business‑critical chillers operate at peak efficiency

To drive cost savings and ensure reliable cooling performance, the financial centre needed its seven business‑critical chillers to operate at optimal efficiency at all times. Traditional on‑site inspections could not consistently detect deviations or subtle efficiency losses, creating a need for continuous monitoring and deeper operational insight.

AI‑powered remote monitoring to optimise chiller operations

Using OpenBlue Services, Johnson Controls remotely monitored all seven chillers and applied AI‑powered diagnostics to identify inefficiencies and performance anomalies. The system detected a chiller running 5ºC higher than necessary in condenser water temperature, an issue that standard on‑site checks would likely have missed. A simple control setpoint adjustment was carried out to correct the deviation and restore optimal operation.

Significant energy savings, improved reliability, and lower emissions

By combining continuous remote monitoring with expert diagnostics, the financial centre made targeted operational adjustments that improved energy performance and equipment reliability. These enhancements supported sustainability goals and extended component longevity.
Key outcomes included:

OpenBlue Services identified a 15% energy‑saving opportunity
