3.2 Structural Workout Romero Ly
SIZE & LAYOUT
Grid of form runs 60m x 40m. Approximately 1,470 sq. meters. A central rectilinear museum block sits in the middle of the building and is the central core for shear, although there are exterior load bearing walls along the edge. A 5m x 5m courtyard sits in the middle of the central museum block, providing atrium-like lighting for the building core, that otherways gets little to no natural daylighting.
GENERAL STRUCTURE
A 5m x 5m modular grid organizes the structure. Steel columns support the structure and sit between the exterior glass panels that make up the perimeter of the building, as well as in bigger spaces such as the cafeteria, library, and lobby. Concrete walls break up the glass facade and make up interior walls to provide shear and additional support. Curved and straight Glu-Lam and CLT beams hold up the thin curved concrete roof structure that provides overhang, especially on the southern corner of the building, and allows for varied ceiling height on the interior.
ROOF STRUCTURE
The roof structure is comprised of curved Glu-Lam beams and CLT girders. A 4” curved concrete slab sits over the roof structure. The roof is going up to 6m in the largest and most public spaces (cafeteria and library), 5m in transition spaces (entrance and circulation), and 4m in the smaller spaces (support and classrooms). This ends up with a high to low facade that reverses itself on the other side.
ENCLOSURE
Structural concrete walls that fit full or half modules, make up the non transparent facade, while glass panels and steel columns make up the transparent portion.
HEATING & COOLING
Because of the transparency of the envelope, the curved roof structure will loop down on the south side of the building. Willow trees will be planted concentrated on the south side to block excessive sunlight when the willow trees mature, but these trees are deciduous so light can come into the building in the winter when it is necessary. Radiant heating will be laid on top of the concrete slab for quick and responsive heating. Geothermal cooling will be implemented for its efficient, sustainable cooling that does not need much maintenance.
