What is Commissioning?

A building can be designed well, specified well and built to drawing, and still waste a fifth of its energy from the day it opens, because nobody checked that the systems actually do what the design intended. Commissioning is that check: the structured process of verifying that plant is installed correctly, configured properly, and delivering its intended performance in the real building. It is the bridge between design intent and reality, and skipping it is one of the most expensive false economies in the whole industry. This lesson establishes what commissioning is, why the performance gap it closes is so large, and what it costs against what it saves.
