From the Honolulu Advertiser: “Ko Olina seeks to tap 6.5 million gallons of seawater a day, though the future ultimate demand is projected to be 11.6 million gallons a day.  The largest projected use of the cold seawater would be to chill water in the air-conditioning systems of four envisioned condominium time-share and hotel buildings.  Using cold seawater to cool buildings promises to cut air-conditioning costs while reducing crude oil consumption and energy demands by using an abundant, reusable resource in Hawai’i.  Seawater air conditioning is a proven technology, which is viewed as having wide application in Hawai’i but to date has been limited to relatively small-scale projects, including one at the Natural Energy Laboratory of Hawai’i Authority on the Big Island.”
