Chilled fresh water will be used to air condition eight state facilities, including the state Capitol building, officials said Tuesday.
The project will reduce electricity usage by more than 5.3 million kilowatt hours each year. (The average U.S. utility customer uses about 11,000 kilowatt hours a year.)
The new effort is aimed at helping the state make progress toward its renewable energy goals.
“Using water largely chilled by the ocean instead of our own electric chillers for our air conditioning needs should result in significant environmental benefits at no additional cost to the taxpayer,” said state Comptroller Roderick Becker.
The eight buildings that will be cooled with chilled water are:
Keoni Ana (1170 Alakea St.)
Kalanimoku (1151 Punchbowl St.)
Keelikolani (830 Punchbowl St.)
Kinau Hale (1250 Punchbowl St.)
Leiopapa A Kamehameha (235 S Beretania St.)
Queen Liliuokalani (1390 Miller St.)
No. 1 Capitol District Building (250 South Hotel St.)
