Interactive tools
The calculators and simulators from our courses, gathered in one place. The free tools below work without an account; the course diagnostics open inside their capstone lessons with a free account.
Free tools
Simple payback from capital cost and annual saving, with the sensitivity that estimate deserves.
Drag the flow and watch the cube law: why a VFD at 80% speed uses half the power a damper would.
Step through the refrigeration and heat pump cycle: where the heat goes and why COP beats 1.
Course diagnostic simulators
Each course ends with a hands-on capstone: a misbehaving system, its data, and the job of finding the money. Free account required.
Run a full simulated site audit: bills, walkround findings and the ranked opportunity table.
Tune a live boiler: excess air, blowdown and flue temperature against fuel cost.
Eight steam call-outs: failed traps, flash losses, condensate return and insulation.
Leaks, pressure, control mode and heat recovery on a misbehaving air system.
AHUs, setpoints, free cooling and simultaneous heating and cooling.
Superheat, subcooling, fouled condensers and COP recovery.
Oversized motors, belt losses, VFD opportunities and power factor.
Over-lighting, LED retrofits, controls and commissioning failures.
U-values, bridging, airtightness and retrofit sequencing.
Bare pipes, economic thickness, cold-line vapour barriers and safe-touch.
Sensor drift, dead bands, schedules and setpoint reset.
Find what commissioning would have caught: drift, overrides and failed sequences.
Fouling, worn plant and the energy cost of deferred maintenance.
Match sources to sinks and size the recovery that actually pays.
Sizing to heat, spark spread and integration failures.
Sensible vs latent sizing, stratification and the flat-tariff trap.
PV sizing, self-consumption, batteries and grid limits.
Payback traps, NPV calls and portfolio sequencing.
Baselines, adjustments and proving savings that survive scrutiny.
Composite curves, minimum utilities and cross-pinch violations.
Eight audit call-outs from scoping to reporting.
A full audit of a working brewery: brewhouse, cellar, packaging and utilities.
