Monitoring-Based Commissioning (MBCx) is a continuous commissioning approach using automated system monitoring, data analytics, and periodic functional testing to identify operational problems, optimize performance, and maintain efficiency over time.
Unlike traditional functional and integrated commissioning of systems at project completion that then disengages, MBCx establishes ongoing performance monitoring through the building automation system (BAS) or dedicated monitoring platforms. The system continuously tracks key performance indicators, energy consumption, temperatures, pressures, flow rates, equipment runtime, alarm conditions, and analyzes data to detect anomalies, inefficiencies, and performance degradation.
The MBCx process includes:
Baseline Establishment: Initial functional testing and monitoring setup establish performance baselines and expected operating parameters. Sensors are calibrated, control sequences verified, and monitoring points configured.
Continuous Monitoring: Automated systems track performance 24/7, collecting data on equipment operation, system performance, energy consumption, and space conditions. Modern platforms use algorithms to detect anomalies, identify trends, and flag potential issues.
Data Analysis: Regular review of monitoring data, weekly, monthly, or quarterly, depending on program intensity, identifies operational problems, control sequence deviations, equipment malfunctions, and optimization opportunities. Advanced platforms use machine learning to improve detection over time.
Issue Resolution: Identified issues are investigated, root causes determined, and corrective actions implemented. Solutions may include control sequence adjustments, equipment repairs, sensor calibration, or operational procedure changes.
Periodic Functional Testing: Annual or semi-annual functional testing verifies systems continue operating correctly under various conditions. Testing addresses aspects not visible through continuous monitoring alone.
Performance Reporting: Regular reports document energy performance, issues identified and resolved, optimization achievements, and cost savings.
MBCx transforms commissioning from one-time verification to continuous improvement, catching degradation before it significantly impacts performance and costs.
Deploying MBCx depends on a variety of parameters, including but not limited to a customer’s existing building automation system capabilities, server and storage capabilities, cybersecurity requirements, and facilities staffing levels.
