When The Brando opened on the French Polynesian Atoll Tetiaroa recently, it did so with a seawater air-conditioning system. The Brando is the second lodging establishment that I am aware of to employ such a system. The InterContinental Bora Bora Resort & Thalasso Spa was the first in the world to do so. The system at that property uses 7,874 feet of pipe that reaches a depth of more than 3,000 feet (the deepest ocean pipe in the world) off the reef of Bora Bora. The pipe feeds the cold seawater through a titanium heat exchanger, transferring the cold into the fresh water circuit that then air conditions the hotel, before returning the seawater back to the sea. According to the InterContinental Bora Bora Resort & Thalasso Spa, the system has zero impact on the environment and is quiet.
