Hitachi launches wooden container-style data centers

Hitachi, Ltd. has launched a new wooden model of its ‘Flexible Design Container’ data center, designed to harmonize with local environments and reduce environmental impact. The modular, container-sized units utilize wood for primary structural components such as pillars and beams.

By replacing steel and concrete with wood, the company aims to facilitate carbon sequestration and reduce CO2 emissions during construction. Hitachi estimates that, depending on the scale, the use of wood can result in approximately 20 tons of CO2 reduction or sequestration. The lightweight nature of wood also allows for easier transport and compatibility with prefabrication methods, potentially reducing on-site labor.

These data centers are intended to support the growing demand for edge computing and the decentralization of digital infrastructure away from major hubs like Tokyo and Osaka. The design allows for easier social acceptance in residential or rural areas by blending into the local landscape. Despite the use of wood, Hitachi states the units maintain high durability and seismic resistance, meeting ‘Class I’ safety standards, and are designed to last over 30 years.
