Responding to today’s evolving challenges, we have endeavored to reduce our building’s environmental footprint at every step. From the earliest stages, TEKKO BUILDING has been designed to fully use “recycled materials" and to introduce “high-efficiency facilities and equipment" as evidenced by our achievement 100% renewable energy in 2020. At the same time, site improvements such as the planting of trees and flora native to the area provide people with a refreshing place to reconnect with nature while improving the quality of the urban environment. Our company is proactively contributing to creating a sustainable society for the next generation.

[Environmental Performance Assessment]

◇Convenient Access to Transportation

・Superb location: 2-minute walk from JR Tokyo Station (JR intercity and regional rail line, Tokyo Metro subway network) and Otemachi Station (Tokyo Metro and Toei subway networks).

◇Water Quality Assurance Plus Reduced Water Consumption

・Appropriate utilization of various greywater for non-potable purposes such as flushing, etc., contributes to reduced consumption of city water. In addition, measures are taken to assure water quality and safety.

◇Business Continuity Support (Intermediate isolation system rated for a shindo 7-class earthquake)

・The seismic performance of the structurally integrated intermediate isolation system has been assessed by the Building Center of Japan (BCJ), and ensures continued the operational integrity of the building even after a seismic event of 7 on the shindo scale of seismic intensity.

◇Improved Comfort of the Indoor Environment

・Automatic solar tracking blinds, natural ventilation, and other building equipment plus a generous power outlet capacity of 75VA/m2 in office areas contribute to a more comfortable work environment.

◇Reduced Energy Consumption (High-efficiency building systems)

・The building’s HVAC system uses state-of-the-art separate sensible and latent cooling (SSLC) technology. By using higher temperature chilled water, the efficiency of a dedicated secondary cooling coil is raised, and energy consumption is reduced.

◇ “Barrier-Free” Design

・The interior of the entire building and exterior grounds of the site have been designed and constructed in conformity with standards and guidelines for facilitating accessibility and usage of buildings and their facilities by the elderly and disabled.

◇Mitigation of the “Heat Island” Phenomenon

・With the aim of helping to mitigate the “heat island” phenomenon in central Tokyo, a variety of measures have been adopted including adoption of water-retentive pavement and the “greening” of the site’s walking path with natural flora, which also provides a place to relax and heal weary spirits.
