Retro-Commissioning: the process of increasing cost savings and improving energy savings for a building that may have not been properly commissioned from the start

• Ideal for: Buildings that have been in existence the longest and are facing commissioning issues and buildings that were never properly commissioned at the start
• Often times this can be hospitals or schools and similar commercial and industrial buildings that have longer lifespans.

Recommissioning: the process of commissioning that takes place after a building has become operational, but has a need for further or additional system solutions.

• Ideal for: Underperforming facilities including operational buildings that need smaller repairs, replacements, and resets
• The building owner may not realize what their facility needs until after the building has been operational for some time. Recommissioning is ideal for buildings that have begun to ‘wear’ or for owners who are looking for ‘green’ energy solutions for their pre-existing mechanical systems
