Structure The main construction is light steel framing and open web steel joists. The plywood sheets applied to the light steel framing resists the shear and lateral forces reacting on the structure. The open web steel joists are located at the roof, spanning the deep floor plate required for the gallery space. These joists are loaded onto a center truss that brings the loads into the walls and ultimately into the slab on grade which the museum sits on. Since the soils are fairly stable and the building is fairly low to the ground and light, there were no needs for piles or a depper foundation system. To create the curvature at the ends of the roof, wide flange beams were used in order to support the weird curvature needed to create the sculptural faces of the building. The roof is then covered with steel decking and then finished and the final exterior materials to waterproof and finish the building 8

Circulation, Egress, and Fire Safety The Southern Utah Museum of Art is a one story building. Therefore, the Egress system works differently then its multi-story neighbors. Egress is more focused on the buildings ability to offer multiple options of egress when leaving the building with exit discharges set at the front and back of the building, allowing one to end up at the public way. The only forms in circulation overlap are in regards to having the main front entrance involved in the form of egress. As for the Circulation of the building The main entrance of the space is placed in the large overhead cantilever at the face of the building. The overhang serves as creating a meeting place that is also cooled down by the summer breeze which then leads into the lovy and main exhibit area. The exterior of the building also slopes in order to work witht he exterior grade conditions of the sidewalk 10

Radiant heated gallery space
The museum utilizes prevailing winds, form, and glazing studies in order to provide proper comfort from a passive point of view. As discussed earlier, a pocket is created at the face of the building that captures summer breezes during the hotter seasons in order to cool users while shading Northern windows from over exposure. The building is formed in order to take advantage of the buoyancy of hot air, allowing heat to travel up and out of the building. In terms of active mechanical systems, the SUMA utilizes a “trigeneration” system that controls ventilation, heating and cooling all at once in order to reduce carbon emissions and needed space. The space utilizes a combination of a radiant cooling and heating system paired with a constant low air volume system. The Building is also paired with sensors that identify what spaces need to have an increase in ventilation due to temperature and/or occupancy. The systems are concealed beneath the building and work in concert with the building form, causing an overall reduction of heating and cooling loads by 45%.

With the Museums focus on sustainablitiy, many green materials are used in the construction. The exterior cladding uses an integrated pigment, instead of paint, which will never require maintenece or re-finishing. Where possible, concrete slabs where left exposed. The panels are fiberglass reinforced concrete with a textured ceramic-like finish that helps draw water to hidden catch basins. The building is shaped to provide shading to its large western windows which maximize daylighting to the main gallery. The window to wall ratio is around forty percent with the majority being on the Western and Northern facade.

REFLECTION
At the beginning of this study, it was expected that the SUMA was a building that only pursued a sculptural emphasis. A space that was meant to be spacious and yet also involve an eye-catching facade on the exterior. However, this edifice proved us wrong. The Southern University Museum of art truly exemplifies systems thinking. Form orientation, Ventilation design, climate modifiers were all thought of in the creation of this building. The use of vegetation to cool the South side of the building while the northern breeze cools the opposing face creates a comfortable exterior. This is well paired with the buoyant form, combined with a radiant floor and a trigeneration system that constructs a reposeful interior. Enough about human comfort though, this building also does justice to its surrounding environment both above and below grade. The materials used were meant to have a low-embodied energy while being low maintenance, mitigating the use of toxic and harmful materials. Furthermore, the roof system creates a natural rainfall collector that takes rainwater and replenishes the aquifer below the museum. The roof and facade are also colored to prevent heat gain and add to the heat island effect through it’s high albedo. Overall, the Southern Utah Museum of Art stands as the quintessence of forward thinking in comfort, health, and systems thinking.
