In the library, light illuminates the space through linear fixtures, creating a bright and comfortable environment. Upon entering, your gaze is immediately drawn to the transparent round bookshelves. Made of white metal, they exude a sense of openness, while the stacked arrangement enhances the spatial depth. Vertical light strips on either side of the bookshelves utilize the permeability of the metal mesh, allowing light to spill through and fill the entire space.

The library's ceiling follows the sequence of interstellar orbits, mirroring the design of the bookshelves. It extends in a staggered and overlapping manner from the inside to the outside, seamlessly integrating with the overall ceiling shape. The once "orderly" ceiling is transformed into an "interesting" one, adding a touch of intrigue.

The lobby of the public area serves as a vital access channel, connecting the first and third floors in its lofty space. Suspended corridors, arranged in an orderly manner, link the spaces on both sides when viewed from the first floor. The combination of sparse and gradual lighting on the neatly organized grilles creates a simple and bright atmosphere. White perforated metal on the side walls enhances the brightness through wall washing effects, with a few localized downlights providing basic lighting for the space.

The corridor spaces on the second and third floors continue the logic of the ceiling design, satisfying the basic lighting needs through grille lights. Decorative metal plates adorn the walls, and linear lights are added in a staggered and orderly arrangement along the stitching pattern, injecting vitality and interest into the otherwise monotonous corridor space.
