Before renovation, it was far from a resplendent atmosphere.

After renovation, the atrium became a comfortable space with warm color lamps; visitors stay there for a longer time. Along the catwalks, where the maintenance is difficult, we installed 78W LED floodlights (2800k) to illuminate the walls. Indirect lighting on the escalator handrail guides the visitors to the main hall foyer (5F).

We achieved prescribed illuminance target 500lx for the atrium entrance and escalator exits with 4 lifting lighting units (8×150W CDM-T very narrow spotlights, 3000k). The energy consumption of the atrium declined to 45% of that of before renovation.
