NTT Com's FDC2 attains LEED-CS 2009 Platinum certification

NTT Communications Com's Financial Data Center Tower 2NTT Communications Corporation (NTT Com)'s Financial Data Center Tower 2 (FDC2) has become the first data center in Hong Kong and China to obtain the LEED-CS 2009 Platinum level certification, the company announced last Thursday.

Launched in 2015, FDC2 is phase 2 of NTT Com's tier-IV-ready financial data center located in the Tseung Kwan O Industrial Estate. FDC1, phase 1, was launched in 2013.

Operating with 4,000 racks, FDC2's data center cooling technologies include a twin cooling battery tower that acts as a thermal energy storage system for the data center; a cooling wall that features a front-flow cooling design with hot aisle containment; with ultra-high density design to support the installation of ultra-tall racks up to 54U; plus power density up to 24kVA per rack.

These contribute to an increase in cooling energy efficiency by over 20%, thereby achieving a market-leading annualized PUE of below 1.5 at full-load, said NTT Com. (Click on this video link for a graphic visualization of the cooling mechanisms in operation.)

According to ASHRAE Standards, FDC2 successfully minimizes energy consumption to around 60% per annum, resulting in the reduction of 357,000 tons of CO2 emissions. These achievements helped the Hong Kong's leading data center attain the full 21 points under LEED-CS 2009 EAc1 Optimize Energy Performance.

FDC2 also adopted a multi-faceted approach, combining design, construction, and operation technologies to avoid, minimize, and mitigate the associated environmental impacts. These included green site selection, green parking, refrigerant management best practices, green construction, enhancement of water use efficiency, reduction of urban heat island effect, enhancement of indoor air quality, optimization of resources utilization, green operation, and the enhancement of thermal comfort.

Reduce data center operation costs

"We are excited to be the first data center in Hong Kong and China to gain this coveted certification. The energy efficiency of a data center is of great concern right now to businesses in Greater China as well as overseas, as they strive to reduce costs and operate in an eco-friendly, socially responsible manner," says Steven So, vice president of data center business, NTT Com Asia. "NTT Communications is a technology pioneer committed to adopting industry best practices and eco-friendly designs to provide efficient, reliable green data center services." 

"Building and operating FDC2 with a "Think Sustainability from the Project's Start" approach solidifies the data center with a strong foundational roadmap from design, construction, and operation, to service delivery," says Helen Cochrane, director of Meinhardt infrastructure and environment and LEED Consultant for FDC2. "FDC2's success showcases how to build and operate a top-notch green data center with innovative technologies. The LEED-CS 2009 certification highlights NTT Com's achievement in attained sustainable development, which is widely recognized by the international green certification organization and market."

In Hong Kong, NTT Communications has previously attained LEED-CS 2009 Gold for Financial Data Center Tower 1 (FDC1) and LEED for Existing Buildings: Operations & Maintenance Silver for Tai Po Data Center.

The award of this certification has been confirmed by the Green Business Certification Incorporation  (GBCI), an international certification and credentialing body which administers LEED (Leadership in Energy and Environmental Design) project certifications to green buildings. FDC2 has also been acknowledged as one of Greater China's most notable green building projects at the Greenbuild China conference in Shanghai on October 16-18.

LEED-CS 2009 (LEED 2009 for Core and Shell Development) is an internationally recognized green building certification rating system developed by the US Green Building Council (USGBC) for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods. The rating system evaluates buildings from different green aspects including sustainable site, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, innovation in design and regional priority.
