TAMACHI TOWER

TAMACHI TOWER

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

Sliding Core Wall Seismic Control System in Tamachi Tower

TAMACHI TOWER has adopted a newly developed seismic control system called the "Core Wall Core Rod 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 and beam frame and slide sideways.
By concentrating vibration control devices around this core wall (core rod), high earthquake resistance is ensured with one-fifth the number of vibration control devices required compared to conventional methods. Reducing the number of vibration control devices allowed us to minimize the building core, enabling us to secure more effective office space.
