Expanding environmentally friendly buildings (green buildings)
Initiative guidelines
Green buildings are an initiative that aims to contribute to the realization of a sustainable environment and improved quality of life for future generations. They are resource-efficient, environmentally friendly, and socially responsible throughout the entire lifecycle of a building, from site selection to design, construction, operation, maintenance, renovation, and demolition, and they are designed to create and operate healthy and prosperous buildings and local communities.
The expansion of green buildings will contribute to increasing the appeal of buildings and areas along the railway line through the construction of sustainable architecture, and we will continue to strive to achieve this as we move forward with building construction and management plans.
DBJ Green Building Certification
Of the real estate properties owned by our group, four facilities have received DBJ Green Building Certification in recognition of their environmental performance, tenant convenience, and the efforts of owners and property stakeholders.
In September 2024, the large-scale complex "NAMBA SkyO" was recertified with the "DBJ Green Building Certification" by the Development Bank of Japan Inc., and in April 2025, three buildings of the Kita-Osaka Truck Terminal - "Kita-Osaka Truck Terminal Building 1 (opened in April 2020)," "Kita-Osaka Truck Terminal Building 2 (opened in January 2014)," and "Osaka Prefectural Food Products Distribution Center Building E (opened in April 2023)" - were recertified with the "DBJ Green Building Certification" by the Development Bank of Japan Inc.
