Retro-Commissioning is typically applied to existing buildings with a goal to identify how to improve the efficiency and operation of energy consuming systems and equipment such as the heating, ventilating, and air conditioning (HVAC), interior and exterior lighting, service water usage and heating.

Retro-Commissioning is typically a four-step process that begins with an analysis of an existing building through study of energy and water efficiency and operation and benchmarking with peer buildings. It prioritizes a list of potential capital improvements from lowest to highest. The process develops a plan to implement energy efficiency and operational improvements.

At the conclusion of retro-commissioning, documentation including findings and improvements is provided and is carried into long term operator processes in the building.
