Ongoing commissioning (OCx) is a systematic process of continuously optimizing building system performance through a blend of onsite inspection and regular monitoring, testing, and adjustment throughout the building’s operational life.<\/p>\n
Building performance inevitably degrades over time through multiple mechanisms. Equipment wear causes mechanical components to operate less efficiently, bearings wear, seals leak, belts slip, and motors lose efficiency. Sensor drift means temperature, pressure, and flow sensors gradually lose calibration accuracy, causing controls to respond to incorrect data. Control sequence modifications occur when well-intentioned operators make temporary overrides that become permanent, defeating energy-efficient strategies. Component failures like stuck dampers, failed actuators, or broken economizers often go unnoticed if they don’t cause obvious comfort problems.<\/p>\n
Research consistently shows commissioned buildings lose 50-80% of commissioning benefits within 3-5 years without ongoing oversight. Energy consumption gradually increases, comfort complaints become chronic, and equipment failures accelerate as systems operate outside design parameters.<\/p>\n
Ongoing commissioning prevents this degradation by establishing regular cycles of performance monitoring, functional testing, issue identification, and corrective action. The process maintains systems in optimal condition, preserves initial commissioning investments, and continuously adapts to changing building use, occupancy patterns, and operational requirements.<\/p>\n
Benefits beyond maintaining performance include extended equipment life through proper operation, reduced maintenance costs by catching problems early, improved occupant satisfaction through consistent comfort, lower energy costs through sustained efficiency, and maintained warranty coverage through documented proper operation.<\/p>\n
Ongoing commissioning is preventive medicine for buildings; regular checkups catch problems before they become expensive crises. The modest annual investment in ongoing commissioning (typically ~$0.10-0.30 per square foot) prevents far larger costs from performance degradation, premature equipment replacement, and lost productivity from comfort problems.<\/p>\n
For buildings where performance, efficiency, and operational excellence matter long-term, ongoing commissioning is essential rather than optional.<\/p>\n
