Analysis of key technical requirements
Case study of energy benchmark establishment
In a central air-conditioning system renovation project in a hospital, the energy performance parameters determined through 90-day base period monitoring include:
- Average daily power consumption in cooling season: 1250kWh
- COP value: 2.8
- Temperature compliance rate: 92%
Implementation suggestions
Four-step method for energy saving verification
- Select the measurement method (option method specified in GB/T 28750)
- Determine the calibration period (no less than 30 days)
- Implement M&V plan (including equipment records and instrument calibration records)
- Prepare verification report (signature confirmation by both parties is required)
Typical problem: A factory lighting renovation project did not establish an initial energy consumption record, resulting in energy savings disputes
