Formula
How this calculator works
This formula converts source operating values into energy per occupied room for quick review.
Energy POR = Total Energy Consumption ÷ Occupied Room Nights
Context
Why this metric matters
industry standard 12 sustainability reporting also includes energy per square foot/meter. Use POR when guest-demand intensity matters most.
Hotel insight
Industry context
- industry standard 12 sustainability reporting also includes energy per square foot/meter. Use POR when guest-demand intensity matters most.
- Small changes in denominator rules can move the result, so keep the same reporting basis when comparing periods.
Operational notes
Before you act on the number
- 180,000 kWh ÷ 2,730 = 65.93 kWh/POR
- Confirm whether internal-use, complimentary, adjustment, or excluded activity should be included before comparing periods.
- Use this result as an operating guide and review it with the supporting business context.
