Which activity ensures that building systems operate as intended after turnover?

• A. Post-occupancy evaluation
• B. Commissioning
• C. Maintenance planning
• D. System commissioning coordination

Answer: (B)

Commissioning is the systematic process of verifying that building systems perform in accordance with the design intent and the owner's requirements, ensuring they operate as intended after turnover. It involves planning, executing functional and performance tests, calibrating equipment and controls, validating the sequence of operations, and training the facility staff. This proactive verification catches issues, confirms proper integration of systems, and provides documented evidence that everything works as designed when the building is handed over. Post-occupancy evaluation looks at occupant experience and actual performance after people use the space, which is valuable but does not focus on verifying the installation and functioning of systems. Maintenance planning covers ongoing upkeep rather than initial verification of performance. System commissioning coordination helps organize testing across subsystems, but the overarching activity that ensures operation is commissioning.
