Case Study: Four Seasons Hotel

Chiller-reassembly

Scope: Upgrade outdated mechanical plant room that dated back to 1981 – when the landmark Sydney hotel was built - with modern, energy efficient equipment and systems.

Delivery Model: Build, Own, Operate and Transfer (BOOT) scheme. 

Benefits: ENGIE Services designed, built, and now own the upgraded plant room. They will operate and maintain the plant for 12 years.
Four Seasons Hotel spent $0 upfront in capital costs. They transferred project risk to ENGIE and got fixed maintenance fees with guarantees for equipment reliability and efficiency over 12 years. At the end of the term, Four Seasons will obtain ownership of a well maintained, optimised plant room.

Results: The hotel has already saved 23% off their electricity bill after the first two months of operating the new plant room. Once system optimisation is complete, the team expect a 26% annual energy savings.

What the Customer Says: 

"The BOOT scheme proposed by ENGIE Services was a unique approach for this type of project. It allowed us to gain the energy savings from installing new equipment and systems without having to make a big capital investment upfront"
