Why simulate a retrofit inside your own plant

Every machine has its own efficiency profile, and each depends on what the others are doing. The machine learning layer fits the operational efficiency profile of every chiller, pump and cooling tower to the site’s own trend data, across the full part-load and lift envelope: thousands of measured operating points per machine, not four rating points.

Candidate equipment is then run through that same calibrated plant model, on the site’s own load and weather, so each option is judged by how it would perform inside the plant it will actually run in.

What’s included

Chiller remediation and replacement

Candidate machines run across the whole part-load envelope on the site’s own load and weather.

Cooling tower remediation and replacement

Tower options simulated inside the same plant model as the chillers they serve.

Pump remediation and replacement

Pump options simulated as part of the whole plant, not in isolation.

Installation of variable speed drives

The effect of adding drives simulated across every load, weather and stage the plant will see.

Twenty-year lifecycle cost, with a confidence band

Each option is costed over twenty years, with Monte Carlo uncertainty on energy price, grid intensity and load. The result is a lifecycle cost with a confidence band rather than a single number.

Pair it with Lifetime Emissions to see whole-of-life tCO₂e and the marginal abatement cost of each option, including refrigerant emissions and low-GWP trade-offs.

What-if analysis inside Full Optimization

Full Optimization includes the what-if analyzer: the simulation engine for equipment replacement and fault fallback, built on the same calibrated twin that drives your control strategy.

Frequently asked questions

How do you compare candidate chillers?

Candidate machines are simulated across the whole part-load envelope, inside your plant, on your load and your weather, rather than compared on rating points.

What does the lifecycle cost include?

A twenty-year lifecycle cost per option, with Monte Carlo uncertainty on energy price, grid intensity and load.

How is it priced?

Per study, scoped from the same calibrated model. Contact us to scope one.
