Protecting the Environment

「Leed 」Certification

Environmental Performance One Key Criterion to Data Center Selection

As a part of efforts to reduce the environmental impact of data centers spread across the four corners of the globe, NTT Communications is taking steps to acquire Leadership in Energy and Environmental Design (LEED) certification, which sets the global standard for green buildings.
Taking into consideration the efforts of global customers to actively reduce their environmental impact, levels of reliability and environmental performance are key factors in the selection of data centers, which consume enormous amounts of electric power. LEED certification is the world’s preeminent system for evaluating green buildings and therefore serves as one key criterion. NTT Communications vigorously engages in activities aimed at reducing the environmental impact of its worldwide network of data centers. In conjunction with these activities, the Company has worked diligently to acquire LEED certification at the following data centers.
Moving forward, we will not only focus on enhancing performance, but also look to build data centers with low environmental impact in order to increase the satisfaction of customers.

* Leadership in Energy and Environmental Design: A certification system for entire buildings promoted by the U.S. Green Building Council that evaluates energy savings and environmental impact.

Hong Kong Financial Data Center Tower 2 (FDC2)

FDC2

Here, we provide details of Hong Kong Financial Data Center Tower 2 (FDC2), whichFDC2. FDC2 acquired LEED Platinum certification in May 2017, the first to secure such accreditation in the China and Hong Kong regions.

Located in Tseung Kwan O on the eastern part of the Kowloon Peninsula to the eastern part of Hong Kong Island, FDC2 employs an innovative front-flow air conditioning cooling wall system and a cooling battery that maintains the temperature of server rooms at 27°C for a period of about 4042 minutes in the event of power failure.

During cold periods when outside temperatures fall below 10.5°C, certain chillers are also shutdown. In this instance, steps are then taken to switchover to an indirect external air conditioning system using a heat exchange process with the cooling tower.

The innovative FDC2 was recognized with LEED Platinum certification for its capacity to iLEED Platinum certification recognizes these innovative means that have helped FDC2 increase its cooling energy efficiency by roughly 20%.
