Hawaii has aggressive goals for reduction of fossil fuel usage through energy efficiency. HNEI’s primary activities in this area include research on high efficiency buildings and building energy management; and support of Sea Water Air Conditioning (SWAC) to replace conventional AC systems. HNEI also conducts research to support the development and deployment of advanced transportation systems with efforts currently focused on the acceptance and integration of electric vehicles.
Building Energy Management
HNEI’s objectives are to support the development and deployment of energy efficient buildings through research, testing and validation of related technologies, education and training, and project collaboration with private and public sector partners.
Seawater Air Conditioning
SWAC has significant potential to decrease the State of Hawaii’s reliance on imported oil, use of potable water, and use of chemical refrigerants to power and cool conventional air conditioning systems. It also has wide-ranging applicability for commercial and defense applications throughout the Pacific Region and elsewhere in the world. HNEI conducts analysis of design and performance enhancement technologies to reduce cost, along with modeling efforts to improve understanding of impacts on the marine ecosystem.

HNEI’s Transportation program is focused primarily on the impact of Electric Vehicles (EVs) in Hawaii. Complementing ongoing programs in other areas (e.g. Alternate Fuels, Fuel Cells & Batteries, and Grid Systems), the objective is to contribute to a sustainable transportation system by analyzing, modeling and demonstrating replacement fuels, infrastructure and critical technologies.
