Water chilled by ocean will be used for A/C

LIHUE — The state is finalizing a project to air condition state facilities in downtown Honolulu with water largely chilled by the ocean.

But the plan hasn’t quite made it to Kauai yet, said Honolulu Seawater Air Conditioning president Eric Masutomi.

“There certainly is the potential for application of the SWAC (Seawater Air Conditioning) technology on Kauai in the future, including the Poipu area on the Garden Isle,” he said Tuesday. “We have not, however, conducted any in-depth analysis of this opportunity as we are currently focused entirely on completing our Downtown Honolulu system.”

The Department of Accounting and General Services and Honolulu Seawater Air Conditioning have finalized the agreement for the eight Honolulu state facilities Tuesday.

The initiative is part of the state’s significant renewable energy efforts.

“This agreement is another huge step forward in our effort to achieve 100 percent renewable energy by 2045 and reduce greenhouse gas emissions,” said Gov. David Ige.

Under the terms of the agreement outlined in a Tuesday press release, HSWAC will deliver water chilled by the ocean that will be used to air condition certain facilities.

DAGS anticipates that the project will reduce the state’s energy consumption by more than 5.3 million kilowatt hours each year.

    If I tried cooling my house with seawater, I’d get fined! When will private homeowners have access to the same energy-efficient technology?
