Large chillers and central cooling plants are often among the most energy-intensive assets on site. Small, well-managed changes in temperatures and setpoints, sequencing and staging, pump and fan control, and reset and optimisation strategies can deliver significant savings and reliability improvements without compromising comfort or process conditions.
Chiller optimisation is the process of improving how chiller plants operate by:
Well-maintained and intelligently controlled chillers run more efficiently, last longer and cost significantly less to operate.
We optimise chiller plants using a data-led approach: understand current operation, design safe improvements to control strategy, then implement and verify results without compromising comfort or process conditions.
We start by reviewing available data such as kWh usage, run hours, BMS trends and alarms. We assess current setpoints, sequences and reset strategies, compare plant operation against actual cooling loads and weather conditions, and add temporary metering or data logging where needed to build a clear, accurate picture of how the system is performing.
Using these insights, we identify opportunities to reduce lift, eliminate unnecessary running and improve chiller sequencing. We recommend adjustments such as refined temperature setpoints, smarter staging and better coordination with pumps and air-side systems. Each change is assessed against safety limits, OEM guidance and plant constraints, then prioritised by benefit, risk and ease of implementation.
We work with your engineering teams and controls partners to implement the agreed changes, monitoring comfort levels, alarms and performance during a proving period. Settings are fine-tuned based on real-world results, and we provide clear before-and-after comparisons to demonstrate savings and efficiency improvements.
Optimised chiller operation reduces electricity consumption and delivers immediate savings.
Stable, efficient cooling reduces faults, prevents overheating and keeps your system running smoothly.
Less strain on compressors and components helps extend the life of your chiller plant.
Lower energy usage directly cuts emissions and supports your organisation’s sustainability goals.

A Building Management System is a central platform that monitors and controls core services, for example HVAC, lighting, metering, and alarms. It gathers live data, then optimises setpoints and schedules to reduce energy use and improve comfort. With one interface, your team can see performance, act quickly, and verify savings.
A BMS lowers energy costs by running plant only when needed and at the most efficient levels. It fine tunes temperatures, trims run times, and prevents equipment from fighting each other. In addition, analytics highlight waste, such as simultaneous heating and cooling or out-of-hours usage. As a result, most sites see quick, measurable savings.
Yes. We design BMS solutions that integrate with common open protocols, such as BACnet, Modbus, and KNX. This approach connects legacy plant, sub-meters, and new IoT sensors into one view. It also reduces vendor lock-in and makes future upgrades simpler and more cost-effective.
Absolutely. For retrofit projects, we survey your site, map points, and phase works to minimise disruption. For new builds, we collaborate with your design team to specify controls, sequences, and dashboards that meet building and compliance requirements. In each case, you receive a tailored strategy and full commissioning.
We apply secure network design, encrypted communications, and role-based access. In addition, we separate control networks from business networks where appropriate and follow best practice for firmware and patch management. Audit trails and user permissions help you meet internal policies and external standards.
You get remote monitoring, alarm triage, and planned maintenance with clear service levels. Our reports show consumption, comfort, and exceptions, so you can evidence performance for ESOS and SECR. Typical payback for targeted BMS upgrades is short, often one to three years, and further optimisation can improve returns over time.
