OptimusAI · by RoyceAI

Energy optimisationoperators actually trust.

OptimusAI finds the lowest-energy setpoints for your chiller plant every few minutes. Before anything is recommended, an AIXpert checks it against live conditions, maintenance and equipment history — and explains the change in plain language.

2AIXpert reviews

Physically achievable27.5 °C is 1.6 °C above wet-bulb — the towers can hold it.
Comfort protectedChilled water held at 7.5 °C — AHU-L5-02 valve already at 94%.
Maintenance respectedCH-4 on PM (WO-2340), kept out of staging.
Equipment historyCT-3 fan capped at 42 Hz after two VSD trips (WO-2281).
Trade-off notedTower fans +31 kW, outweighed by chiller and pump savings.
Safe to apply. Net saving 64 kW — about S$460 a day at this load.
Why two brains

Maths finds the saving. AI checks it's safe.

Optimisers are good at numbers but blind to context. When a recommendation ignores a chiller on maintenance or a starving AHU, operators override it — and the savings disappear.

Optimiser alone

A number, with no reason.

  • Doesn't know CH-4 is down for maintenance
  • Can't see the AHU already at 95% valve
  • Repeats setpoints that tripped a VSD last month
  • Operators override it, so savings don't stick
OptimusAI

A checked recommendation, explained.

  • Reads CMMS, alarms and trends before recommending
  • Holds comfort-critical setpoints automatically
  • Learns from equipment history and past trips
  • Operators understand it, so savings stick

How it works

Four steps, every few minutes.

The optimiser does the maths. The AIXpert does the judgement. You stay in control of what reaches the plant.

01 · Model

Plant twin

A kW model of your chillers, towers and pumps, built from your own trend data.

02 · Optimise

Search setpoints

Finds the lowest-power combination for today's wet-bulb and cooling demand.

03 · Review

AIXpert checks it

Tests the proposal against live conditions, maintenance, limits and history — then explains it.

The review

What the AI checks before you see a number.

Physical limits

Condenser water above wet-bulb plus approach. Chiller lift, minimum flow and surge margins.

Comfort

AHU valve positions and zone temperatures — chilled water held when any area is short.

Maintenance & faults

Equipment on PM or with open faults is kept out of staging.

Equipment history

Past trips and call-backs set caps — no repeating a setpoint that failed before.

Weather & demand

Forecast wet-bulb and load, so a saving now doesn't cause a scramble later.

Tariff & peaks

Peak-demand windows and tariff bands weighed into every recommendation.


Control modes

Start advisory. Earn your way to autonomous.

Every change is logged with the checks behind it, so you can prove savings and roll back anything.

Live

Advisory

Recommendations and explanations only. Your operators make every change.

Live

Approve to apply

One click writes the checked setpoints to your BMS. Trial for two hours first if you like.

Pilot

Autonomous within limits

Applies inside a safe envelope you define, and reverts automatically on any alarm.

Proof

Savings you can show the finance team.

OptimusAI compares as-operated against optimised using a baseline model of your plant, so the saving is measured — not estimated.

Baseline model

Trained on your plant's history to show what it would have used without OptimusAI.

As-operated vs optimised

Switch views live on the plant schematic to see where every kW went.

Monthly savings report

kWh, kW/RT and dollars saved — ready for Green Mark and the finance team.
