What is Functional Performance Testing (FPT) and why is it critical in BCxP?

• A. Tests that only verify installation.
• B. Tests that verify system performance.
• C. Tests that confirm systems perform to design intent under actual operating conditions; demonstrates compliance with OPR/BOD.
• D. A type of acceptance criteria for equipment.

Answer: (C)

Functional Performance Testing focuses on verifying that building systems operate as intended when they run together under real operating conditions, not just as individual components. It links how the equipment, controls, sequences, and sensors behave to the project requirements and the basis of design, across the actual loads and conditions the building will face. This is why it’s critical in BCxP: it confirms that the design intent is realized in practice, demonstrates compliance with the owner’s project requirements and basis of design, and validates that the integrated system delivers the expected energy performance, comfort, and safety. It goes beyond simply checking installation or confirming that equipment functions on its own; it tests the system in operation and under realistic conditions, catching issues that only emerge when everything works together.
