Honolulu Star-Advertiser - - BUSINESS - Star-Ad­ver­tiser staff

The state De­part­ment of Ac­count­ing and Gen­eral Ser­vices said Tues­day it has reached an agree­ment with Honolulu Sea­wa­ter Air Con­di­tion­ing LLC to air-con­di­tion eight state build­ings, in­clud­ing the Capi­tol.

The state said in a news re­lease it ex­pects the switch to sea­wa­ter air con­di­tion­ing “will re­duce state con­sump­tion of elec­tric­ity by over 5.3 mil­lion kilo­watt-hours each year and avoid the pro­duc­tion of 10 mil­lion pounds of car­bon diox­ide an­nu­ally. Ad­di­tion­ally, potable wa­ter con­sump­tion is ex­pected to drop by 11.4 mil­lion gal­lons per year, and sewage dis­charge will be re­duced by over 1.7 mil­lion gal­lons yearly in build­ings cov­ered by the pre­lim­i­nary agree­ment.”

The seven other build­ings cov­ered un­der the agree­ment 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.) and No. 1 Capi­tol District Build­ing (250 S. Ho­tel St.).

The Sea­wa­ter Air Con­di­tion­ing com­pany takes cold wa­ter from deep in the ocean, uses it to cool fresh wa­ter at a cool­ing sta­tion, then pumps the cold fresh wa­ter to build­ings’ air con­di­tion­ing units.
