Building commissioning is the process that ensures building systems operate as intended after installation. This comprehensive process involves verifying and validating that all building systems, such as HVAC, lighting, plumbing, and electrical systems, are designed, installed, and function according to the project's operational requirements and the owners’ needs.

During commissioning, a team conducts thorough inspections, testing, and adjustments to ensure that everything aligns with the design specifications and functions properly. This process also includes training building staff on the systems for proper operation and maintenance, helping to identify and rectify any issues before the building is fully occupied.

While post-occupancy evaluation assesses how well a building meets the needs of its occupants after they have started using it, and systems calibration focuses specifically on tweaking control systems for optimal performance, neither of these processes ensures that the systems operate as intended right after installation. Facility management, on the other hand, is mainly concerned with the ongoing maintenance and management of the building after occupancy rather than the initial commissioning of systems. Thus, the correct answer highlights the crucial role of commissioning in the successful operation of building systems.
