What does the term 'retro-commissioning' refer to?

The term 'retro-commissioning' specifically refers to the process of improving the performance of existing building systems. This process involves a systematic investigation and analysis of existing building operations, typically for buildings that were not commissioned when they were constructed or for those that have gone through changes over time. The goal is to identify and implement operational improvements, which can lead to enhanced energy efficiency, improved occupant comfort, and overall better system performance.

Essentially, retro-commissioning allows building owners to realize the original design intent of their systems or adapt to changes in usage patterns or technology that have occurred since the building was first built. This improvement process can significantly reduce energy consumption and operational costs, making it a valuable practice in facility management and sustainability efforts.
