Project Description:

This proposition presupposes the following: an exhibition space, computer terminal space, laboratory, or performance space where direct sunlight inside peak workday hours is undesirable.

The solution detailed comprises a steel I-beam structural frame that supports a titanium rainscreened, layered facade.

The primary material choice, titanium, provides strength, resistance to rain, and non-discolored runoff. The corrugation increases strength, and provides a vertical module whereby shingle style offset layering creates short hexagonal cells which may be open gasketed to provide drainage. Venting of horizontal bands at each overlap allows for leverage of positive pressure against the panels to force air through the area between the rainscreen and watertight/airtight layers.
Motion of the rainscreen under wind loads, snow, rain is mitigated by neoprene padding of windowshade cantilever support, and spring isolation to steel I-beam structure. Silicon caulking is employed to address expansion/contraction/motion of window construction v. wall construction. IGUs are compression loaded into frames.

Titanium color promotes reflection of radiation induced temperature gain. Cantilevered panels reduce direct sunlight interior temperature gain. Double IGUs with large airgap prevents heat loss through penetration. Panel insulation outside of water barrier deters cold bridging.
Diffuse interior illumination is promoted through diffuse reflection from lower panel and inside window shade. Interlocking/overlap of corrugation provents radiation damage to weather barrier.
Corrugation and material density, coupled with multiple panel wall, double IGU with asymmetrical airgap decrease sound transmission from exterior. Load of façade is tranferred via battens to spring loaded I-beam, while window construction shares an I-beam with concrete deck floor platforms.

Material strength of façade enhanced through folding and judicious layering of panels.
