What type of testing ensures that building systems operate properly before occupancy?

Acceptance testing is a critical phase in the commissioning process that verifies and ensures that building systems are functioning according to the design specifications and intended performance criteria before the building is occupied. This type of testing is conducted after installation but prior to the handover of the building to the owner or occupants. The goal of acceptance testing is to identify any deficiencies or issues that need to be resolved, ensuring that all systems—such as HVAC, plumbing, and electrical—operate effectively and efficiently.

By undergoing acceptance testing, any problems can be addressed promptly, enhancing user satisfaction and ensuring compliance with regulatory standards. This proactive approach is vital in confirming that the building meets operational needs and supports the health, safety, and comfort of its future occupants. It is a foundational step in the commissioning process that establishes the reliability of the systems installed in the building.
