Formula
How this calculator works
This formula converts source operating values into water per occupied room for quick review.
Water POR = Total Water Consumption ÷ Occupied Room Nights
Context
Why this metric matters
industry standard 12 also contemplates water per available room and cost per m³/gal. POR is useful for guest-service intensity benchmarking.
Hotel insight
Industry context
- industry standard 12 also contemplates water per available room and cost per m³/gal. POR is useful for guest-service intensity benchmarking.
- 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
- 1,365 m³ ÷ 2,730 = 0.50 m³/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.
