This building conveys modernity through the articulated structural supports of its balconies and roofs and the skewed roofline. The interior has an open beam, vaulted ceiling, exposed ducts, dropped lighting, and perforated stainless steel grillework. The structure houses the offices, workshops, and laboratories of the staff for the submillimeter array (SMA) on Mauna Kea, and, like the Subaru building (HA46.3), includes a remote operations center to allow full operation of the summit's observatory equipment from Hilo. The SMA is cutting-edge technology which studies the submillimeter band of the electromagnetic spectrum between visible and radio wavelengths. The submillimeter array is a joint project undertaken by the Smithsonian Astrophysical Observatory and Taiwan's Academia Sinica Institute for Astronomy and Astrophysics.
