Building Commissioning

Building Commissioning is a systematic and documented process of ensuring that the owner's operational needs are met, building systems perform efficiently, and building operators are properly trained.

Goals

Commissioning new buildings: To deliver a building that operates as it was designed, complete with fully trained building operators.

Commissioning is the process of ensuring that systems are designed, installed, and functionally tested and are capable of being operated and maintained to perform according to the design intent.  Commissioning begins with planning and includes design, construction, startup, acceptance and operational training.

Retro-commissioning existing buildings: Retro-commissioning is a systematic process for improving and optimizing a building’s operations and maintenance.  Its focus is usually 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 for the owner, and identifying and fixing existing problems.
