Study on power usage effectiveness metering methods of data centers

Based on national standards and metrological method requirements, this study examines current issues in power usage effectiveness (PUE) metering for data centers. The analysis covers five key elements: metering boundary selection, instrument placement, meter management, system framework, and data acquisition and processing. Practical recommendations are provided for each element. Using an operational data center case, this paper demonstrates the PUE metering process and shows how energy efficiency measurements enable energy conservation and carbon reduction. These findings thus serve as a practical reference for improving PUE measurement and data utilization in data centers.
