Trade-Off Simulation: A Priced Frontier for Each Trade-Off

Run hours against energy, chilled water temperature against flow rate. The same calibrated twin that optimizes your controls puts the efficient operating points for each trade-off on a frontier, priced, before anyone commits to one. Comfort and room temperatures stay the same.

What it answers

Controls optimization 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 chilled water temperature against flow rate to find the efficiency sweet spot, with comfort and room temperatures unchanged. Each trade-off gets its own frontier of efficient operating points, 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 the efficient trade-offs between balanced runtime and plant efficiency sit on one frontier.

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

How it’s delivered

Trade-Off Simulation is scoped from the same calibrated model as controls optimization and quoted per study. All modeling, tuning and verification is done remotely, with read-only data access and no write access 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 optimization?

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.
