NELHA, Hawaii

1986: the Natural Energy Laboratory of Hawaii Authority, Keahole Point, Hawaii began the successful utilization of SWAC in their main laboratory building. Deep-water pipelines were already installed to provide cold, nutrient rich, seawater for research purposes in alternate energy and aquaculture. Since a cold water supply was already incorporated into the infrastructure, it was decided to utilize the cold water for cooling. Today, the use of SWAC has been expanded to a new administration building and a second laboratory. Estimated monthly saving in electricity is $2000.
