Smarter cooling. Zero capital.
Verified savings.
AI-driven chiller efficiency optimisation for large commercial facilities. Dotz connects sensors, meters and your existing chiller controls, then continuously optimises operation through the Dotz AI Control Centre — fully funded, with verified savings shared 50/50 from day one.
Target cooling savings
*Target savings vary by site, existing controls, climate and operating profile — confirmed against an agreed baseline.
Lower cooling cost, without capital expenditure.
Commercial buildings often over-cool to protect comfort, while fragmented controls and fixed schedules leave savings unrealised — cooling is one of the biggest controllable energy costs a building has.
Of electricity bills can be driven by air conditioning.
Typical chiller share of commercial A/C energy use.
High peak demand, rising bills, carbon-reporting pressure, comfort complaints and limited visibility into what the plant room is doing.
Target cooling kWh savings from adaptive optimisation.
Customer keeps half of every verified saving, from day one.
Fully funded and controlled by Dotz — sensors, integration, AI control, monitoring and reporting are managed through the Dotz AI Control Centre.
Chiller optimisation that turns building data into live actions.
Dotz connects sensors, meters, BMS/BAS and chiller controllers, then continuously optimises setpoints, staging and schedules through one AI control centre.

Predictive cooling, comfort-safe control.
Dotz ChillerAI learns each building's thermal behaviour and forecasts cooling needs in real time. The objective isn't to cool less — it's to deliver the required comfort using fewer kWh, fewer peak events and better equipment sequencing.
Learn
Temperature, humidity and equipment behaviour are learned by building zone.
Forecast
Cooling demand is forecast from weather, occupancy patterns and history.
Optimise
Chiller staging, setpoints, pumps and schedules are tuned within agreed comfort limits.
Prove
Savings, carbon and performance are reported through Dotz dashboards.
Verified savings, split 50/50 from day one
A performance-based model — Dotz only earns its share once savings are metered and verified against the agreed baseline.

Dotz ChillerAI
Sensors, metering & AI control — funded and operated by Dotz
The chiller plant your building already runs. Dotz ChillerAI adds sensors, metering and AI control around it — not a replacement.
Minimal disruption
Deployed around live site operations and existing cooling requirements.
Chiller retained
No mechanical replacement — your existing chiller plant stays in service.
Fully managed
Dotz installs, monitors and optimises the system for the life of the agreement.
Non-invasive integration
Standard communication protocols connect into your existing plant room and controls.
One control plane for heat, cooling, storage and recovery.
ChillerAI isn't a stand-alone black box — it feeds the same live operating layer that runs the rest of the Dotz Energy stack. Real-time monitoring, AI-driven optimisation, remote alerts and ESG/carbon reporting all run through one dashboard, whether the load is heating or cooling.

Common questions
What is Dotz ChillerAI?
Dotz ChillerAI is an AI-driven chiller efficiency optimisation feature of the Dotz Energy stack. It connects sensors, meters, BMS/BAS and chiller controllers, then continuously optimises setpoints, staging and schedules through the Dotz AI Control Centre — installed, monitored and optimised by Dotz.
Do we need to replace our existing chillers?
No. ChillerAI is a non-invasive overlay — sensors, metering and AI control are added to the chiller plant you already run using standard communication protocols. There is no mechanical replacement.
How much can we save on cooling energy?
Target savings are 17–35% of cooling kWh, depending on the site's existing controls, climate and operating profile. Savings are measured against an agreed baseline, not estimated.
How is the commercial model structured?
ChillerAI is delivered on a 50/50 shared-savings basis: verified cooling savings are split evenly between the customer and Dotz, from day one. Dotz funds the sensors, integration, AI control, monitoring and reporting.
Will comfort be affected?
No — the objective isn't to 'cool less'. ChillerAI optimises chiller staging, setpoints and schedules within customer-agreed comfort boundaries (temperature, humidity and operational limits), so it delivers the required comfort using fewer kWh.
How long does installation take?
Target installation is 4–6 weeks, subject to site access and BMS readiness, across five stages: site review, baseline, integrate, learn and control, and verify.
How are savings measured and reported?
Live metering feeds the Dotz AI Control Centre, which reports cooling kWh saved, cost and CO₂ reduction against the agreed baseline through monthly savings statements and optimisation reviews.
Does ChillerAI work alongside Heating as a Service?
Yes. ChillerAI feeds the same live operating layer as the rest of the Dotz Energy stack — heating, cooling, storage and recovery are managed through one AI control centre.
