This five story EBB lab located near the University of California, Berkeley campus houses molecular and microbial biology research, including lab rooms, cold/hot rooms, green houses and offices.

L+U developed the luminous stair in collaboration with the SmithGroup to thread through the building vertically and visually tie the floors together. Mock-ups and simulations were used to fine tune the LED source, the diffusion panels and riser-grating for uniform stair lighting and ease of maintenance.

Mock-up for luminous staircase and false color HDRI to study luminance.
