What is Building Commissioning?



Definition

Building commissioning (Cx) is the process of verifying building subsystems such as mechanical (HVAC), plumbing, electrical, lighting, wastewater, controls, etc to ensure systems are operating as intended.



Why it's important

Building commissioning takes place during the construction phase of a building. However, even after all systems are verified, there tends to be a downward drift in performance over time. In response, many owners and operators will have retrocommissioning performed to methodically test and adjust each critical building system.

Thanks to advances in technology, there is now building commissioning software that enables owners and operators to continuously commissioning each system in a building during normal operations. With this strategy, any drift in performance can be addressed in the fly, and time can be saved on the front end because it is no longer necessary to test and adjust each system individually.
