Capstone: Commissioning Diagnostics
Hands-on: diagnose eight commissioning call-outs — flow balancing, performance shortfalls, sequence defects, sensors, setpoints, duct pressure, drift and handover — then calculate, verify and decide whether to sign off.

You've learned what commissioning is, how to test performance, balance flows, verify sensors and sequences, document the handover, and re-commission to fight drift. This capstone puts you on site as the commissioning agent — running the acceptance tests, finding the gaps between design and reality, and deciding what to fix before you sign anything off. The thread through every case: commissioning is the bridge between design intent and actual performance. Fifteen to thirty per cent of new buildings have a significant performance gap, and the cardinal sin is accepting a handover that doesn't meet design — because fixing a defect after handover costs ten times what it costs now.
