What was the intervention?
The hotel upgraded its bathrooms with water-saving taps and shower systems.
The investment ranged from €2,000 to €14,000, depending on the number and type of fixtures installed throughout the property.
Results
Overall water use dropped by 21.5%, with:
17.6% reduction in cold water usage
33.2% reduction in hot water usage
Water consumption per guest per day fell from 321 litres to 252 litres, a notable improvement in operational efficiency.
The hotel achieved annual savings of up to €12,000 on combined water and energy bills.
Thanks to lower utility costs, the hotel recouped its initial investment in just 1 to 2 years, demonstrating the financial viability of the upgrades alongside environmental benefits.
Key Findings
Installing water-efficient fixtures can result in immediate reductions in resource use without compromising guest comfort.
The reduction in hot water use led to considerable energy savings, amplifying the financial return.
This case highlights a compelling combination of sustainability, cost savings, and fast payback, making it an attractive model for other hotels.
