Introduction of Green Leases

As of the end of November 2022, DOI has concluded green lease contracts for 7.9% of its entire portfolio (based on total floor area). Shinjuku Maynds Tower is working with tenants to promote the installation of LED lighting fixtures and energy reduction and energy reduction in Shinjuku Maynds Tower

Distribution of Sustainability Guides

Each Investment corporation has been distributing and posting the Sustainability Guide to tenants and residents of the properties they own since 2023. The guide includes the Asset Manager's sustainability policy and examples of specific sustainability initiatives that can be easily put into practice, and is used to raise awareness of the need to combat global warming and achieve the SDGs

Supply Chain Management

In order to promote environmental and social initiatives in its supply chain, the Investment Corporation has established a Sustainable Procurement Policy. When selecting new property management companies, suppliers, etc. or evaluating existing counterparties, the status of their sustainability-related initiatives is included in the criteria, along with their facilities management services, lease operation and management services, leasing services, etc., and they are required to understand and cooperate with the Investment Corporation's environmental and social initiatives.

Energy-Saving Efforts through Tenants

As an initiative aimed at tenants, the Investment Corporation is implementing awareness-raising activities to reduce energy consumption in our properties. For some properties, digital signage is installed in common areas such as EV halls to indicate energy consumption. In addition, Shinjuku Maynds Tower makes use of its website to visualize electricity consumption for each tenant.

Urban Development/Revitalization

DOI has been engaged in the urban development business of acquiring development sites and developing office buildings, with "NihonbashiBakurocho1-chome Development Project" (completed in November 2022) and "Kandasudacho2-chome Development Project" (scheduled for completion in June 2024) as examples. Both of these projects are contributing to the strengthening of disaster prevention functions in the area by replacing multiple aging buildings with a single building.
NihonbashiBakurocho1-chome Development Project is contributing to the revitalization of the area by creating a mixed-use building with not only office space but also retail space on the lower floor. In Kandasudacho2-chome Development Project, we are working on urban development and urban redevelopment while taking the environment into consideration, such as by creating open green spaces.

Investment in mixed/multi-use property

Each Investment corporation owns mixed-use properties (DOI: Shinjuku MayndsTower, E SPACE Tower, etc.; DLI: AIP KachidokiEkimaeBuilding, etc.). They include commercial facilities such as convenience stores and restaurants, and medical facilities such as clinics and nursing homes, etc. Through investment in mixed-use properties, they contribute to improving living convenience for office workers and neighborhood residents and revitalizing local communities.

Environmental risk assessment at the time of property acquisition

In acquiring real estate, each Investment corporation obtains real estate appraisal reports and engineering reports, in addition to on-site inspections and disclosed materials from the seller, and conducts surveys related to hazardous substance content in the building, soil contamination status, etc.

Commitments for undeveloped sites

Considering the impact of development activities on the target site and the surrounding natural environment and ecosystems, DOI aims to make buildings in each development project capable of obtaining environmental certification in principle.
The NihonbashiBakurocho1-chome Development Project received a 3-star BELS certification in November 2022, and the Kanda-Sudacho2-chome Development Project has adopted a design with excellent energy-saving performance, with primary energy consumption less than 60% of that of a conventional building, which reduces the burden on tenants' utility costs. The Kanda-Sudacho2-chome Development Project is aiming to become the first building in DOI's portfolio to acquire ZEB Oriented certification.
