TAMACHI TOWER

TAMACHI TOWER an office building built on the site of the former Satsuma clan residence, close to the entrance to the old Tokaido road.
The building's exterior is characterised by a semi-outdoor "Winter Garden", the first of its kind in Japan, which offers a glimpse of a system that encourages communication among workers. In addition to creating such an attractive workplace and improving the well-being of workers, sustainability has also been taken into consideration, with facade fins optimised through environmental simulations for sun shading and natural ventilation.
We have pursued the "next-generation office standard" from multiple angles, including BCP measures with a patented core rod-type vibration control system. By utilizing the comprehensive design system, we have improved the functionality of the entire town block, such as by developing a three-dimensional outdoor plaza and strengthening functions that contribute to the local community, and are contributing to the development of the local community.

Sliding Core Wall Seismic Control System in Tamachi Tower

TAMACHI TOWER has introduced a newly developed seismic control system called the "Core Wall Core Rod Type Vibration Control System."
The core section, from the second basement floor to the fifth floor, is an RC core wall that can be separated from the surrounding steel column-beam frame and slid sideways.
By concentrating vibration control devices around this core wall, we were able to ensure high earthquake resistance with only one-fifth the number of vibration control devices required compared to conventional methods. By reducing the number of vibration control devices, we were able to minimize the building core, enabling us to more effectively secure office space.
