The Palaceside Building will introduce a system that tells you by blinking LED lamps when all stalls in the east and west elevator-tower restrooms are full. We installed it experimentally in the fifth-floor east men's and women's rooms; there were no issues and users liked it, so we will roll it out to all east and west restrooms on floors 1–9 around March.
The mechanism is not complex. A magnetic switch (it conducts when magnets meet) goes on each stall so the circuit closes when the door shuts. When every stall on that side is full and all doors are shut, current flows. Then LED lamps on the wall between the urinal area and stalls (men) or between the wash area and stalls (women) blink to say they are full =photo above.
Harmony of design and function is one Palaceside Building trait. The elevator towers, besides their distinctive white look, place restrooms along a curved wall — praised as design and as efficient use of space. But unlike a straight row you cannot see through from the entrance, so you had to go to the back to know if a stall was free — the "weak point." From now, unless the LED is blinking, some stall is open.
Also, seat cleaners that had been only in women's rooms were installed this week in men's rooms from B1 to the ninth floor =photo below. Spray cleanser on toilet paper and wipe the seat.
The Palaceside Building will keep working to improve convenience for users.
