Needs
Rosewood Hotel The Guanahani wanted to accelerate their transition toward sustainability by lowering their buildings’ conventional energy consumption (2 929 784 kWh/year, or 425 878 €/year prior to Energaya’s consulting services).
Solutions
Energaya conducted a House Energy Rating, including an energy consumption assessment, an improvement program plan, and an economic report.
Step 1: Energy consumption assessment & balance
Energaya analyzed the hotel’s energy consumption and ranked it according to most energyconsuming locations (guest suites, laundry rooms, and more) and uses (HVAC, laundry, and more).
Step 2: Improvement program
Adjusting the contract power
To avoid overpaying for excess energy.
Increasing awareness around ecofriendly behaviors
To inform clients and staff on the best energy-saving practices.
Ensuring guest suites’ roofs are thermally insulated
To prevent avoidable energy losses.
Investing in thermodynamic water boilers
To use less energy when heating water.
Installing new-gen engines and power inverters in the pools
To use less power in pool management.
Building a photovoltaic power station
To avoid conventional energy overconsumption and save money in high-energy activities (housekeeping, etc.)
Step 3: Economic & Environmental report
Implementation costs: 1 707 544 €
Financial savings: 94 855 €/year
Energy savings: 22,27 %, i.e. 427 tons of CO2 emissions avoided
Results
With an initial investment at 9 750 €, our mission enabled the hotel to save 6 500 € a year. As a first step, we analyzed their electricity consumption and adjusted their utility contract accordingly. Our suggestions allowed them to recuperate the cost of the entire study within a year and a half.
