Efficiency Metrics
Understanding efficiency scores and how sites are ranked.
AICE Power provides efficiency metrics to help you identify your best and worst performing sites.
Efficiency score
The efficiency score is a composite metric that rates how well a site uses energy compared to similar sites. It considers:
- Consumption per unit area — kWh/m2
- Weather-adjusted consumption — DJU-normalized values
- Peak-to-average ratio — how spiky the demand profile is
- Disaggregation breakdown — proportion of consumption by category
Efficiency leaderboard
The Welcome page (Accueil) shows an efficiency leaderboard ranking all your sites. This helps you:
- Identify top performers to replicate their practices
- Spot underperformers for targeted improvement
- Track progress after implementing energy efficiency measures
Interpreting the metrics
| Metric | Good | Investigate |
|---|---|---|
| kWh/DJU | Decreasing over time | Increasing without operational changes |
| Peak-to-average ratio | Close to 1.0 | Above 2.0 (spiky demand) |
| CVC variability | Low (consistent consumption) | High (erratic consumption) |
Improving efficiency
Identify the worst performers [step]
Start with the lowest-ranked sites on the leaderboard.
Pinpoint the cause [step]
Use disaggregation to identify which category (HVAC, refrigeration, lighting) drives excess consumption.
Set targets [step]
Compare against top-performing sites to set realistic targets.
Monitor progress [step]
Watch the efficiency trend after making changes.
The Scatter Plot on the CVC auto-comparison page is the most powerful tool for separating weather effects from operational changes when evaluating HVAC efficiency.
