Commissioning is a process that occurs as a new building/system is nearing completion. A systematic set of actions are taken to prepare for pre-start testing and startup. Data is collected on the performance of the equipment with specific application to the characteristics of each piece of machinery, it’s operational conditions, and interrelationship with other connected systems and controls.

O.C. McDonald has adapted the startup and guidelines established by the Sheet Metal and Air Conditioning Contractors of North America (SMACNA), which is widely accepted for startup and commissioning in North America. We have successfully utilized the SMACNA startup and commissioning process for many of our high profile projects.

Retro-Commissioning is currently being employed on existing buildings that are operating inefficiently and at high energy consumption levels. Retro-Commissioning often pays for itself in a relatively short period of time when opportunities to utilize energy efficient strategies are put into place.
