Capstone: Commissioning Diagnostics

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.
