After
- Return of invest: 6 months
- INITIAL SITUATION
- Hotel operation with additional indoor pool facility
- Constant water consumption independent of guest occupancy levels
- High ongoing costs for water, energy and wastewater
- IMPLEMENTATION
- Installation completed in November 2024
- Equipped all guest rooms and public areas
- No structural changes required — universal fit, installed in minutes
Key insight - the 19% figure is conservative
The indoor pool was included in the measurement baseline. Since pool water consumption remains constant and is unaffected by GREENJET, the reported 19% saving is actually understated. Real savings in guest rooms and faucets alone are significantly higher than 19%.
“Measurable savings in real hotel operation — without any loss of comfort for guests.”
