Measure energy used by the event inside a declared operating window and normalize it to a denominator that can be repeated.
E01SUSTAINABILITY CRITERION
Energy
Measure energy used by the event inside a declared operating window and normalize it to a denominator that can be repeated.
Event energy intensity
kWh / attendee
Interval or meter readings, fuel/thermal conversion, event operating window, attendance, baseline period.
Event-period electricity + thermal energy (kWh) ÷ verified attendance.05 · TARGET
Good / Better / Best
Use the threshold as an assessment reference. If an event adopts a different threshold, publish it before measurement and keep it stable for comparison.
GOOD≥10% reduction
BETTER≥20% reduction
BEST≥30% reduction + source disclosure
Minimum evidence
Meter exports or invoices; event operating log; attendance record; baseline calculation file.
Without source data, the criterion score is capped at 40/100.
Pre-publication check
- ✓Boundary and event window are written down
- ✓All energy carriers are included or exclusions are named
- ✓Attendance denominator is traceable
- ✓Baseline uses the same boundary
- ✓Calculation file and source evidence are retained
