Your chiller plant at its lowest-energy point, every minute.
Our AI predicts the cooling load and sets chillers, pumps, cooling towers and air handlers to the most efficient combination that still holds comfort. It works with the chillers and BMS you already have.
We start with your plant data and a site walkthrough.
- Cooling load
- 1,150 RT
- Plant power
- 712 kW
- Chilled water supply
- 6.8 °C
GreenBOS Twin, live chiller plant view. Switch the AI off to see the same plant on its fixed schedule. kW/RT is the electricity the plant uses per ton of cooling; lower is better.
Example data, not a client site.
Cooling is close to half of a building's energy. Most plants still run on staging rules and setpoints fixed at commissioning.
- 01
Chillers staged by fixed rules
Chillers come on and off by time or by a single temperature, not by the load the building actually needs.
- 02
Pumps and fans at full speed
Pumps and cooling tower fans run harder than the load needs, hour after hour.
- 03
Setpoints nobody revisits
Chilled water and condenser setpoints stay where they were set on day one, whatever the weather.
Four steps from your first reading to savings you can audit.
- 01
Connect
Sensors and a gateway go in next to your BMS. Nothing in the plant is replaced.
- 02
Baseline
We measure the plant as it runs today, in kW/RT and kWh, so every saving has a reference.
- 03
Optimise
The AI stages chillers and sets water temperatures, pump speeds and tower fans every few minutes.
- 04
Verify
Savings are measured against the baseline and reported every month.
Fail-safe by design. If our connection drops, the plant falls back to its existing sequencer. Cooling never depends on us.

Your request is tagged Chiller Plant Optimisation, so it goes straight to the chiller team.
How you pay
No upfront cost with Savings-as-a-Service.
You pay from the energy the plant saves, and the system is yours after five years.
What is Chiller Plant Optimisation?
Chiller Plant Optimisation improves the efficiency of your existing cooling system by monitoring performance, identifying inefficiencies, and optimising operations to reduce energy consumption without compromising cooling comfort.
How much energy can we save?
Energy savings depend on your plant's current condition, operating patterns, and efficiency. We assess your existing system to identify potential improvements and estimate achievable savings.
Do we need to replace our existing chillers?
Not necessarily. Our optimisation solutions are designed to improve the performance of existing chiller plants. Equipment upgrades may be recommended depending on the condition and requirements of your system.
What happens if the actual savings are lower than expected?
We review the system's performance data to identify potential causes and recommend adjustments. Any financial arrangements related to underperformance depend on the agreed contract terms.
