EBCx stands for?

• A. Existing Building Commissioning
• B. Existing Building Certification
• C. Extended Building Commissioning
• D. Energy Building Commissioning

Answer: (A)

Existing Building Commissioning is the process of applying a formal commissioning approach to a building already in operation to improve its energy performance and the reliability of its systems. It focuses on optimizing how the building’s existing equipment and controls run, verifying that systems operate as intended, and identifying practical opportunities for energy savings. This is distinct from commissioning for new buildings, which targets ensuring design intent during construction. The other options describe certification, an extended term, or an energy-only phrasing, none of which match the established meaning of EBCx.
