Policy on Obtaining Sustainability Certifications
Mitsubishi Estate recognizes that addressing environmental and social considerations in real estate and indicating performance on these considerations externally is important to meet the expectations and demands of stakeholders such as tenants and investors. Therefore, the company has a policy of proactively obtaining sustainability certifications whenever possible.
In Japan, Mitsubishi Estate has obtained certifications that include DBJ Green Building Certification, Comprehensive Assessment System for Built Environment Efficiency (CASBEE), and Building-Housing Energy-efficiency Labeling System (BELS), while the main certifications obtained overseas include Leadership in Energy and Environmental Design (LEED) and BRE Environmental Assessment Method (BREEAM) certifications.
| Evaluation/Certification System | Overview |
|---|---|
| DBJ Green Building Certification |
DBJ Green Building Certification is a certification system established by the Development Bank of Japan (DBJ) in April 2011 as an initiative to support environmentally and socially conscious management of real estate. Based on a comprehensive assessment which covers such areas as environmental performance, disaster prevention, community considerations and other stakeholder engagement, the system evaluates and certifies real estate anticipated by society and the economy. |
| Comprehensive Assessment System for Built Environment Efficiency (CASBEE) |
CASBEE is a system for comprehensively assessing the quality of buildings, including interior comfort and consideration to landscape as well as environmental considerations such as energy conservation and use of materials and equipment with low environmental impact. It was developed by a research committee established for comprehensive environmental assessment of buildings in April 2001 as a collaborative project between industry, academia, and government under the auspices of the Ministry of Land, Infrastructure, Transport and Tourism, and has been continuously upgraded and maintained since. |
| Building-Housing Energy-efficiency Labeling System (BELS) |
BELS is a system for the assessment and certification of energy efficiency performance in newly built and existing buildings by a third-party organization. In April 2016, the scope of the system was expanded to residential buildings, and it was designated as one of the third-party certifications in the Guidelines on Building Energy Efficiency Labelling based on Article 7 of the Act on the Improvement of Energy Consumption Performance of Buildings (Building Energy Efficiency Act). Association for Housing Performance Evaluation and Labeling (Japanese only) |
| Leadership in Energy and Environmental Design (LEED) certification |
LEED is a system for assessing environmental performance of buildings and site use developed and operated by the U.S. Green Building Council (USGBC). |
| BRE Environmental Assessment Method (BREEAM) certification |
BREEAM is an environmental assessment system developed by Building Research Establishment Ltd. (BRE) in the U.K. in 1990 as a tool for assessing the sustainability performance of buildings, communities, and infrastructure. Performance is assessed in a total of ten categories including energy, health and well-being, water, materials, and waste, and rated on a five-point scale of Pass, Good, Very Good, Excellent, and Outstanding. |
| WELL Building Standard |
This is an environmental performance evaluation system for buildings and urban subdivisions with a focus on health and wellness. It is operated by International WELL Building Institute (IWBI) and certification is handled by Green Business Certification Inc. (GBCI). The latest version, WELL v2, was launched in 2020, and consists of the following 10 concepts: air, water, nourishment, light, movement, thermal comfort, sound, materials, mind, and community. |
| SITES Certification |
The Sustainable SITES Initiative (SITES). Designed by the U.S. Green Building Council (USGBC), which designs and updates the LEED rating system, the certification is administered by Green Business Certification Inc. (GBCI) in the U.S. It offers guidelines and a quantitative evaluation system on green infrastructure design, technology, and management. Certification is now available outside the U.S. with v2. |
| Energy Performance Certificates (EPCs) |
A system for assessing the energy efficiency of buildings on a seven-point scale from A to G. In accordance with the Minimum Energy Efficiency Standard (MEES) stipulated by law in 2015, office buildings that fail to achieve a B rating by 2030 can no longer be newly leased to tenants. |

Promoting ZEB and ZEH in New Buildings and Rental Apartments to Reduce Environmental Impact
Otemachi Gate Building
Mitsubishi Estate acquired its first ZEB Ready (office category) certification for Otemachi Gate Building, a high-rise tenant office building, previously known as Uchi-Kanda 1-chome Project, which is scheduled for completion at the end of January 2026. The energy conservation measures employed in this project are tested at the Group’s headquarters to ensure they are energy efficient and facilitate a comfortable environment. Starting with this property, the Group aims to achieve high environmental performance in line with ZEB requirements for all new buildings to be developed. Furthermore, Mitsubishi Estate Residence makes it its goal to meet or exceed the ZEH-M Oriented Standard in new condominiums and new rental apartments under its CO2 emissions reduction strategies (formulated in January 2022). The entire Group will work together to reduce the environmental impact of its buildings and to provide new value.
Acquisition of SITES® Gold Certification for Tokiwabashi Tower and TOKYO TORCH Park, Thereby Becoming the First Urban Mixed-Use Development Project in Japan to Acquire Such Certification
TOKYO TORCH Park
TOKYO TORCH Tokiwabashi Tower and TOKYO TORCH Park have acquired SITES® Gold Certification, an environmental certification that evaluates primarily the sustainability of landscapes, becoming the first urban mixed-use development project to receive such a certification in Japan.
Furthermore, these sites have been registered under Edo-Midori Green Area, a system by the Tokyo Metropolitan Government for registering and publicly announcing green spaces where native plant species are actively planted and where biodiversity is conserved. With this registration, TOKYO TORCH Tokiwabashi Tower and TOKYO TORCH Park have now acquired five environmental certifications—the others being DBJ (Development Bank of Japan) Green Building Certification, Social and Environmental Green Evaluation System (SEGES) certification, and Association for Business Innovation in Harmony with Nature and Community (ABINC) certification.
