NOAA Daniel K. Inouye Regional Center (IRC)

The ground floor of the main entrance boasts a three-story high central atrium containing a comprehensive exhibit area with pictures, videos, signage and artefacts depicting various NOAA programs, as well as a library, auditorium, media room and cafeteria. ITIC and PTWC are located on the third floor of the IRC.

The facility's design, inspired by Hawaiʻi's climate and culture to feature wind, water and sun, utilises natural lighting, the absence of mechanical fans, and passive cooling and ventilation systems supported by a seawater well. It also captures renewable energy through solar photovoltaic and solar thermal systems. NOAA's Science on a Sphere projection system hangs seemingly in midair in the lobby of the main building. The facility is Leadership in Environmental and Energy Design (LEED) Gold Certified.
