Trade-Off Simulation: Every Efficient Operating Point, Priced

Run hours against energy, comfort against cost. The same calibrated twin that optimises your controls puts every efficient operating point on one curve, priced, before anyone commits to one.

What it answers

Controls optimisation is where most engagements start and where the savings come from. The same calibrated models then answer the questions a plant has never been run to answer, starting with what a runtime target costs in energy.

Trade-Off Simulation sets run hours against energy and comfort against cost. Every efficient operating point sits on one curve, priced, before anyone commits to one.

What’s included

Run hours against annual energy

For a single plant, or for several plants joined by an interconnector.

Runtime balance against efficiency

Presented as a Pareto frontier of simulated staging strategies, so every efficient trade-off between balanced runtime and plant efficiency sits on one curve.

Maintenance deferral, priced in kWh

The energy cost of a maintenance decision, known before a runtime target is set.

Mechanical performance, baselined alongside energy

Every engagement builds chiller, pump and cooling tower performance models and mechanical baselines. Trade-Off Simulation prices changes against them.

Starts and stops per machine
Short cycles and short-cycling ratio
Runtime per cycle and cycles per day
Runtime balance between low-load and high-load chillers
Peak demand

How it’s delivered

Trade-Off Simulation is scoped from the same calibrated model as controls optimisation and quoted per study. All modelling, tuning and verification is done remotely and air-gapped: nothing connects to plant control.

The model is trained on historical data shared through API integration or as a flat-file export from the BMS: six months minimum, twelve ideal, at 15-minute intervals or better.

Frequently asked questions

Can you model several plants joined by an interconnector?

Yes. Run hours against annual energy can be simulated for a single plant or for several plants joined by an interconnector.

Is this a separate model from controls optimisation?

No. Trade-Off Simulation is scoped from the same calibrated model and quoted per study.

How is it priced?

Per study. Contact us to scope one, or email contact@exergenics.com.
