Needs
With its Green Globe certification, Christopher St. Barth Hotel wanted to accelerate their transition toward sustainability by lowering their buildings’ conventional energy consumption (1 725 902 kWh/year, or 298 058 €/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 ( laundry rooms, and more) and uses (HVAC, hot water, 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.
Installation of a heat pump drye
To reduce the laundry room’s energy consumption
Installation of a Building Management System (BMS)
To closely monitor the performance of the main energy-consuming systems
Step 3: Economic & Environmental report
Implementation costs: 630 505 €
Financial savings: 77 551 €/year
Energy savings: 25,98 %, i.e. 289,95 tons of CO2 emissions avoided
Results
With an initial investment at 8 850 €, our mission enabled the hotel to save over 12 000 € 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 in less than a year.
