For operators and power engineers

The boiler room gets a say.

If you know the boiler room, your objections belong in the work early. PENGA is only useful if the model respects what the plant actually does.

Operator notes

What the model needs to respect

Outdoor resetCurrent curve, seasonal adjustments, manual overrides.

Winter callsCold complaints, hot floors, nuisance alarms, known bad zones.

Plant limitsLead/lag behaviour, lockouts, service history, access constraints.

Ground rules

The people responsible for heat stay in the loop.

PENGA helps an owner understand the opportunity without bypassing the people responsible for practical plant behaviour.

PENGA does not command boilers, pumps, valves, reset curves, or occupied-space conditions during the first assessment.

The best feedback names what would be unsafe, unclear, inconvenient, hard to measure, or too expensive to justify.

Any active project would need field data, owner acceptance, operator confidence, qualified review, and clear fail-safe behaviour.

Questions for review

The best feedback makes the work safer and more useful by naming what the building actually does in winter.

What plant data would make the savings and comfort analysis credible?
Which operating modes or lockouts does the model need to understand before drawing conclusions?
Where could instrumentation, access, cybersecurity, or maintenance become a nuisance?
How do overheating, cold calls, and comfort uncertainty get reported without false precision?
What would make a future control project unacceptable?
