Key Metrics Explained

Metric	Formula	Optimal Range
Total Energy Input	Electricity + (Gas × 29.3) + (Fuel × 33.7)	As low as possible
Energy Intensity	Total Energy ÷ Production Output	< 10 kWh/unit
Renewable Share	Renewable Energy ÷ Total Energy × 100%	> 30%
Resource Efficiency	Recycled ÷ Materials × 100%	> 50%
Circularity Index	Recycled ÷ Waste × 100%	> 50%
Carbon Footprint	Electricity × Carbon Intensity ÷ 1000	< 100 tons/year

BEROAS Rating Scale
