HKAEE - Energy Retro-Commissioning Technical Talks for HVAC Systems – Knowledge, M&V and Big Data Analytics
2021-05-21

Topic Retro commissioning Using Big Data Analytics Approach for Optimisation, Fault Diagnostics, Measurement and Verification Retro commissioning RCx is a process to systemically review energy performance of building services systems in buildings The MVAC system has the highest energy demand in buildings, its common operation issues such as sensor fault and inefficient operation can be identified through big data analytics For water side systems, sensor biases and mismatching equipment sequencing can result in inefficient operation at chiller plants Traditionally the control settings of chiller plants are determined according to design data which does not take into consideration of equipment deterioration caused by aging and/or retrofitting Using advanced data analytics tools, end users can easily identify sensor inaccuracy, performance issues of equipment, and inefficient control settings RCx in a data driven approach using advanced technologies is an effective way to improve overall energy performance of chiller plants For air side systems, sensor inaccuracy and unnoticed faults (e g improper valve and damper control) are the common reasons causing energy waste and/or discomfort cooling Operation data collected from BMS and wireless IoT sensors can be used for analysis and diagnosis to identify unnoticed faults Applying big data analytics and IoT technologies in RCx can unlock many energy saving opportunities Insightful information can be readily accessed by end users, RCx consultants and contractors, enhancing operation efficiency from all perspectives...
