Commissioning & Retro-Commissioning


P1 Group’s Commissioning Services provide an important quality assurance benefit to customers as well as a comprehensive way to protect their investment in their buildings.

Commissioning is an efficient process of ensuring systems are designed, installed, inspected and functionally tested. It also shows whether they are capable of being operated and maintained to perform according to the design intent. The process includes planning, design, construction, startup, acceptance and operational training.

Retro-commissioning is a systematic process for improving and optimizing a building’s operations and maintenance. Its focus is on energy-using equipment such as mechanical equipment, lighting and related controls. The retro-commissioning process most often focuses on the dynamic energy-using systems with the goal of reducing energy waste, obtaining energy cost savings and identifying and fixing existing problems.
