Commissioning

Building commissioning is a systematic approach of verifying and documenting that building systems are designed, constructed, and operating as intended. Systems we typically commission include HVAC, plumbing, electrical, life safety, lighting, power management, and renewable energy systems.

There are four phases in the commissioning process, pre-design, design, construction, and operation. The pre-design phase is typically when the Commissioning Authority is selected, and the Owner's Project Requirements document is developed. 

The design phase is when the Commissioning Authority develops the commissioning specifications for the project and conducts design reviews of the project's drawings and specifications. The goal of design phase commissioning is to document the design team's reasonings and decisions relating to the Owner's Project Requirements and to bring up any concerns to the appropriate parties.

During the construction phase, the Commissioning Authority reviews and comments on product submittals, develops the commissioning checklists, maintains the deficiency issues log, and coordinates and witnesses functional performance testing.

The operation or final phase of the commissioning process is when the Commissioning Authority reviews any building automation system (BAS) trend logs, coordinates the resolution of the remaining deficiencies discovered during the construction phase, and witnesses any seasonal or differed testing. When done properly, commissioning tends to fill the gaps in the project's communication process and provides Owners with buildings and systems that work properly and comply with the Owner's Project Requirements.
