One deep pipe brings that cold ashore to cool the estate's hotels, farm, apartments, homes, commercial and community buildings, and the marina's shops and food hall, for a fraction of the electricity of conventional air conditioning.
Air conditioning is the largest electricity use in Caribbean hotels and homes. Seawater air conditioning (SWAC) draws its cold from the deep ocean instead, using about a sixth of the electricity. It is proven at Bora Bora, Tahiti's hospital and Réunion.
The farm, fish farms and cold stores are anchor customers, and capacity, metered and connection charges make SWAC an income stream in its own right.
Reaches cold water about 3 km offshore; the used seawater goes back to depth, never into the lagoons.
A shore plant passes the ocean's cold to the estate's chilled-water loop.
Chilled water runs to every connected building in insulated pipe laid with the roads, metered at each building.
A small chiller fleet cools the first buildings, then stands by for the hotels and critical rooms.
Cold water cools and dries the greenhouse air, and the condensate is reused.
Fish tanks and refrigeration plant are cooled by the same cold seawater.
SWAC starts small and grows with the estate. Chiller modules and the network come first, cluster by cluster with the roads, so every building has air conditioning from its first day. When the connected load reaches the build gate, one deep pipe is laid to carry the whole peak, and the chillers stay on as backup.
Equipment is bought direct from whichever country offers the best overall deal, with export credit from that country's agency expected to fund most of the imported equipment.
