What is Retro-Commissioning?

Retro-Commissioning is the application of the commissioning process to an existing facility, which in most cases has never been commissioned. The objective in retro-commissioning is to verify and document the performance of existing building systems in their present day operating conditions and compare that to the owner’s original intent or to a benchmark high performing building of similar type.

Retro-commissioning seeks to improve how building equipment and systems function together. Depending on the age of the building, it can often resolve problems that occurred during design or construction, or address problems that have cropped up throughout the building’s life. In all, retro-commissioning improves a building’s operations and maintenance (O&M) procedures to enhance overall building performance and extend its life and value.
