The Tower uses a spot network 3-line power reception system, which is a power receiving system with high supply reliability. The risk of total power failure is minimized in the event of even a serious accident. If there is a power outage, tenants are supplied with 15VA/m² of electric power from the emergency power generator.
Corresponding to the new legislation, the elevator control system prevents the elevator from starting to operate when the doors remain open. Under the system, minor initial tremors are detected and the elevator stops the nearest floor before a quake's shaking arrives.
The Tower employs a vibration control system with oil dampers and unbounded braces at appropriate positions to absorb the vibrations of earthquakes and strong winds.
