Cooling towers in tropical climates like Hawaii face unique environmental challenges, including high ambient temperatures that reduce operational efficiency and increase water consumption. Evaporative cooling systems, common in ice houses, require significant water resources and can contribute to local water stress. Refrigerant management is critical, as leaks of high-GWP refrigerants can have a substantial climate impact. Facilities like Keehi Ice House must comply with U.S. EPA regulations under the Clean Air Act and the Kigali Amendment to minimize their environmental footprint.
