The Hawaii Gateway Energy Center (HGEC) is a 3,600 sf, $3.4 million facility situated on the south coast of Kona on the Big Island of Hawaii. The new building serves both the Natural Energy Laboratory of Hawaii and the Hawaii Ocean Sciences and Technology Park. And as you may be able to gather from the images and models below, HGEC is a fascinating display of the future potential for synergies of solar power and building efficiencies. The entire building is designed as a thermal chimney that captures heat and creates air movement using the structural form and thermodynamic principles. Also, with the help of glazing, the building orientation and design pretty much eliminates the need for electric lighting during the day. Notably, HGEC consumes about 20% of the energy that’s required by a comparable building.
