What is retro-commissioning primarily intended to achieve in existing buildings?

• A. To boost initial design aesthetics
• B. To verify and optimize building systems performance after occupancy
• C. To reduce construction time by 50%
• D. To replace all components regardless condition

Answer: (B)

Retro-commissioning focuses on verifying and optimizing the performance of building systems after occupancy. It involves checking that systems—like HVAC, lighting, and controls—are operating as intended, then calibrating sensors, adjusting setpoints and sequences, and correcting faults or inefficient operation. The goal is to improve comfort, reliability, and energy efficiency based on how the building is actually used, not just how it was designed on paper. This is why the best choice is that retro-commissioning aims to verify and optimize performance after occupancy. The other options miss the point: aesthetics aren’t the focus, construction time isn’t relevant once a building is occupied, and retro-commissioning doesn’t require replacing all components—often it’s about improving performance with existing equipment.
