Documentation and training are essential components of the commissioning process, as they ensure that building owners, operators, and maintenance personnel have a thorough understanding of the system’s operation, maintenance, and troubleshooting requirements. Comprehensive documentation includes system manuals, operation and maintenance guides, and as-built drawings, while training programs cover topics such as system operation, performance optimization, and fault detection. Proper documentation and training enable effective system management, reduce downtime, and ensure that the system continues to operate at peak performance over its lifespan.
