Existing building commissioning process is best described as?

• A. A quality-focused process for attaining the CFR of an existing facility and its systems and assemblies, focusing on planning, investigating, implementing, verifying, and documenting that the facility and its systems are operated and maintained to meet CFR, with a program to maintain enhancements for the remaining life.
• B. A process for new building design only.
• C. An energy audit with no verification.
• D. A process to replace all equipment.

Answer: (A)

Existing building commissioning is a structured, quality-focused process applied to an operating building to ensure its systems perform to defined performance criteria and can be operated and maintained effectively for the remainder of the building’s life. It guides activities in planning, investigating, implementing, verifying, and documenting, with the aim of confirming that the facility and its systems meet the required performance and that improvements are sustained through proper operations and ongoing enhancements.

This isn’t about design for a new building, nor is it just an energy audit without verification, and it isn’t simply a program to replace equipment. It centers on validating and optimizing how the building performs in its current state and ensuring the investments in improvements deliver lasting benefits.
