《GB/T 39532-2020能源绩效测量和验证指南》由TC20（全国能源基础与管理标准化技术委员会）归口，TC20SC3（全国能源基础与管理标准化技术委员会能源管理与节能评估分会）执行，主管部门为国家标准化管理委员会。
Introduction
Interpretation of the core content of the standard
This standard is equivalent to ISO 50015:2014, establishing a unified framework for energy performance measurement and verification (M&V), which is applicable to quantitative evaluation of energy performance improvement implemented by various organizations. Its core value lies in improving the credibility of energy performance improvement results through standardized measurement and verification processes.
Key Terminology
| Terms | Definition points | Application scenarios |
|---|---|---|
| Measurement and verification boundaries | The physical or logical boundaries of the organization/facility/system | Determine the scope of impact of energy efficiency improvement measures |
| Energy benchmark | A reference for comparing energy efficiency improvements | Basic reference for energy savings calculation |
| EnPI | Quantitative indicators of energy performance parameters | Core measures of energy efficiency levels |
Analysis of the implementation process
- Plan formulation: Clarify measurement boundaries, EnPI indicators, and data collection methods
- Benchmark establishment: Establish an energy baseline based on historical data
- Measure verification: Confirm the effective implementation of energy efficiency improvement measures
- Data analysis: Calculate the actual energy performance improvement effect
- Result report: A complete report including uncertainty analysis
Technical key points comparison
| Elements | ISO 50015 requirements | GB/T 39532 adjustments |
|---|---|---|
| Term definition | 22 terms | Integrated into GB/T 13234 and other standards |
| Appendix structure | Includes uncertainty examples | Deletes illustrative content |
| Implementation guidelines | General principles | Added Chinese industry application instructions |
Uncertainty management
The standard requires the identification of 13 sources of uncertainty, including:
- Choice of measurement method (such as overall measurement vs. point measurement)
- Data collection frequency (needs to cover the operating conditions)
- Instrument accuracy (calibration status influence)
- Model bias (R² value of regression analysis)
It is recommended to use sensitivity analysis to quantify key uncertainty factors.
