Whether you are designing a new building or retrofitting an existing one, commissioning can ensure that your heating, cooling, and other building systems work efficiently together to save energy and reduce your operating costs.

• Building commissioning provides documented confirmation that building systems function according to criteria set forth in the project documents to satisfy the owner's operational needs. Commissioning provides a quality control check, from project inception through the installation and operation of energy-efficient equipment. Commissioning existing systems may require developing new functional criteria to address the owner's current requirements for system performance. 

• A "commissioning authority" or Cx authority is an objective advocate of the owner who leads, plans, and coordinates the commissioning team and commissioning process. The Cx authority can be an independent consultant or a qualified employee of the Owner.

• Frequently, even with good project teams, proper equipment may get installed and perform its intended function of heating or cooling, but it may not operate efficiently. The commissioning process corrects these shortcomings and insures that equipment, controls, and systems are running efficiently.

Commissioning for Existing Buildings

Commissioning for existing buildings (sometimes referred to as retro-commissioning) is a systematic process for investigating, analyzing, and optimizing the performance of building systems.  This includes improving system operation and maintenance to ensure they perform as intended over time. This process helps make the building systems perform interactively to meet the owner's current facility requirements.
