Case Studies
Wyndham Alltra
Playa del Carmen
Kleverness' Energy Management System (EMS) showcased an impressive 53% reduction in energy consumption during a comprehensive 6-month study conducted in collaboration with Playa Hotels & Resorts.
Addressing the Imperative for Occupancy-Based Energy Management in Hotels
Hotel rooms, despite being vacant approximately 70% of the time, contribute to nearly 80% of a hotel's total energy consumption. Meeting global sustainability targets, such as those outlined in the UN Global Compact and the Paris Agreement, requires substantial reductions in carbon emissions. The U.S. Department of Energy emphasizes the potential for energy savings between 30-50% in buildings by implementing monitoring and automation for HVAC systems, lighting, and window shades.
Methodology
This study focused on energy consumption analysis at the Wyndham Alltra Playa del Carmen Hotel. The comprehensive approach included a visual inspection of the hotel's facilities, a comparison of conventional rooms with those equipped with the Kleverness HVAC control system, and the installation of ABB energy sub-meters to validate savings.

Calculation considerations:
- Both rooms operated during the same period of time.
- 30 days per month were considered
Analysis
On-site analysis revealed significant potential for energy savings in air conditioning. The manual control of Minisplit units by guests resulted in high energy consumption, presenting an opportunity for improved efficiency. Additionally, an identified area for improvement involved humidity control to preserve furniture conditions. While there was an opportunity for incremental savings in lighting, the hotel already featured LED lamps, minimizing energy consumption.
Strategy
Leveraging Klever Hospitality sensors and thermostats, the strategy encompassed occupancy control, humidity management, delta T control, and thermal insulation control. The primary goal was to demonstrate the superiority of the Kleverness system in achieving savings compared to the conventional control method.
Procedure
A comparative study was conducted, with some rooms equipped with the Kleverness solution and others manually controlled. ABB sub-meters were installed to validate the obtained data. Over a 6-month period, readings were collected for Minisplit units in both room types.
Results
The trial yielded an average savings of 185.51 kWh per Minisplit unit in 30 days, translating to a substantial 53% reduction in energy consumption when extrapolated to cover all 287 rooms. This promising outcome suggests a potential return on investment exceeding 100%.
Conclusion
The study conclusively demonstrated a 53% reduction in air conditioning energy consumption with the implementation of the Kleverness system.
This finding highlights the significant opportunity for energy savings across the entire hotel.
Kleverness stands out as the sole manufacturer capable of delivering a cost-effective solution that aligns with essential control strategies and ensures a minimal upfront investment for this property.
