Um-Yang: The movement of dark and cold and bright and hot. The upper Sun Pavilion canopy bathes visitors in an ebb and flow of shadows, and momentarily eclipses the sun each day at solar noon. The lower Moon Pavilion is a double walled thermos that holds a reservoir of cooling water, replenished by tidal action twice daily.

The Promise of Blue: A life-giving resource that inhales and exhales with the cycle of the day and seasons — From a distance the pavilion appears as an iconic image suggestive of water, waves, liquid transparency. As the visitor approaches along the breakwater, the image resolves into an undulating metal canopy, floating above an immense, open horizontal wood platform. Under the shade of the canopy, a glass pavilion covers the extensive exhibition spaces emergent from beneath the platform. The pavilion’s public platform is parallel to the breakwater, while the glass pavilion and the tectonic orientation of the canopy above are shifted 13 degrees to align to the larger celestial order, true north/south. The canopy is designed to occlude high overhead sunlight, allowing more light during the winter and morning and evening hours. Each day at solar noon the canopy momentarily eclipses all direct sunlight, eventfully marking the time of day.

The ascent from the breakwater to platform is conceived as a kind of “submergence “: the visitor walks up and through a redundant field of gentle ramps which like a shoreline appear to erode the body of the platform. Once on the deck and under the canopy, the visitor can wander through the canopy-dappled light to the water view or to the exhibition entry at the eastern end of the glass pavilion. The entry, marked by a smaller canopy, provides a control point for the exhibition organizers; stairs, elevators, escalators are organized to ensure ease of circulation from this point.

The exhibition area is divided between the Sun Pavilion, an upper level glass roofed thematic exhibit hall, and the Moon Pavilion, a lower exhibit hall wholly contained under the platform level.

A diamond netlike system of steel supports provides structure for the glass roof and walls of the Sun Pavilion. Protected by the canopy above, only dappled light enters the thematic area, preventing overheating and sun damage. The enclosure of the vertical circulation cores on the upper level and the large wall surface on the lower level, provide locations for the interactive media walls that are linked to the Expo Digital Gallery.

Visitor amenities such as seminar rooms, the interactive technology center and the ocean research resource library are located on a mezzanine level overlooking the Best Practice Area (BPA).As visitors descend from the light-filled upper level to the BPA they directly experience the pavilion’s natural, ocean interactive, cooling technology in the sustainable technology area. The lower level, like a thermos is constructed of a double wall that acts as a reservoir of cool water, replenished by tidal action twice daily. The cool water is brought through the inner wall and allowed to circulate through a network of capillary-like pipes, drawing excess heat from the space.

The Thematic Pavilion is intended to serve a complementary role to the Big-O. Whereas the Big-O is a representative thematic space focusing on the creation of an actual marine environment, the Thematic Pavilion explores our experiential connection to the ocean as life giver.
