# Energy Review & Performance Indicators

> ISO 50001:2018 (EnMS) – cl.6.3 energy review. Baseline energy use,
> identify Significant Energy Uses (SEUs), set EnPIs, plan improvement.

| Review period | YYYY |
| Boundary | Facilities/systems in EnMS scope |

## 1. Energy baseline

| Energy source | Consumption (period) | Unit | Cost | CO2e |
|---------------|----------------------|------|------|------|
| Electricity | N | kWh | $ | N t |
| Gas | N | m3 | $ | N t |
| Fuel (fleet) | N | L | $ | N t |
| **Total** | | | | |

## 2. Significant Energy Uses (SEUs)

| SEU | Area | Share of total | Current performance | Improvement potential |
|-----|------|----------------|---------------------|-----------------------|
| HVAC | Building A | 35% | kWh/m2/year | high |
| Compressed air | Production | 20% | leaks estimated N% | medium |
| Lighting | All | 12% | legacy fixtures | high |

## 3. Energy Performance Indicators (EnPIs)

| EnPI | Definition | Baseline | Target | Normalization factor |
|------|------------|----------|--------|----------------------|
| EnPI-01 | kWh per unit produced | N | -N% | production volume |
| EnPI-02 | kWh per m2 (building) | N | -N% | floor area, occupancy |

## 4. Action plan

| Measure | SEU | Expected saving | Cost | Payback | Owner | Due |
|---------|-----|-----------------|------|---------|-------|-----|
| LED retrofit | Lighting | N kWh/yr | $N | N yrs | @name | |
| Leak repair program | Compressed air | N kWh/yr | $N | <1 yr | @name | |

## 5. Operational controls for SEUs

- Maintenance criteria, operating parameters, staff awareness for
  each SEU – links to work instructions.
