The Unbuilt Terminal is defined by a generative algorithm that synthesizes environmental performance with structural optimization. By mapping solar trajectories onto the roof’s organic curvature, the system calibrates the density and orientation of skylight apertures to maximize natural illumination and passive solar gain. This computational approach ensures that the rhythmic colonnade of the facade is not merely ornamental but emerges as a direct tectonic extension of the roof’s load-bearing nodes, dissolving the distinction between skin and skeleton into a singular, high-performance transit environment.
