Which activity verifies and documents the performance of building systems to ensure they operate as intended before occupancy?

• A. Commissioning
• B. System integration testing
• C. Cold shut testing
• D. Acceptance testing

Answer: (A)

Commissioning is the systematic process of verifying and documenting that building systems operate in accordance with the design intent and project requirements, and it is conducted before occupancy. It involves planning, design review, installation verification, functional performance testing, adjustments, and turnover documentation to prove that systems such as HVAC, electrical, plumbing, controls, and life-safety operate as intended and that the owner has clear operation and maintenance information. While system integration testing focuses on how subsystems work together and acceptance testing often centers on contractual compliance, commissioning provides the comprehensive verification and documentation needed to ensure overall building performance before people move in.
