Which post-acceptance activity focuses on monitoring after occupancy?

• A. Post-occupancy monitoring
• B. Off-season testing
• C. Correct unresolved issues or conduct re-tests
• D. Review usage changes

Answer: (A)

Post-occupancy monitoring is the activity that tracks how the building performs once occupants are using it. It collects real-world data on comfort, energy use, indoor environmental quality, and equipment operation to verify that design and commissioning assumptions hold true in practice and to spot issues that didn’t appear during testing. This ongoing monitoring helps confirm that the building delivers expected performance and guides adjustments if needed.

Off-season testing focuses on system behavior during a season when demand is different, not on continuous performance after occupancy. Correct unresolved issues or conduct re-tests involves addressing problems found during commissioning and verifying fixes, not the routine monitoring that happens after people start using the space. Review usage changes looks at how spaces are used and may influence adjustments, but it isn’t specifically about ongoing post-occupancy performance monitoring.
