Commissioning Authority

A Commissioning Authority (CxA) is a professional responsible for ensuring that a building's systems—such as heating, cooling, lighting, and energy management—are designed, installed, tested, and operate as intended for optimal performance. They coordinate with designers, contractors, and operators throughout the project to verify that all components work together efficiently, meet project goals, and comply with standards. Essentially, the CxA helps ensure the building functions reliably, sustainably, and cost-effectively from the start, improving quality, occupant comfort, and long-term performance.
