NTT Com's LEED Platinum HK FDC2 cuts 60% energy costs

NTT Com's FDC2 facility awarded LEED Platinum certificationNTT Communications Corporation (NTT Com)'s Financial Data Center Tower 2 (FDC2) located in the Tseung Kwan O Industrial Estate, has become its first data center in Hong Kong to gain the LEED-CS 2009 Platinum level certification.

Developed by the U.S. Green Building Council (USGBC), the LEED-CS 2009 (LEED 2009 for Core and Shell Development) is an internationally recognized green building certification rating system developed for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods.

The comprehensive 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.

The certification is expected to reinforce NTT Com's brand promise to foster a sustainable environment and achieve operational efficiency. "[The certification] underscores the continuous efforts we have taken to ensure that FDC2 achieves the best sustainability and lowest carbon footprint possible, while our society and environment can benefit from our commitment to bringing a greener future with innovative technologies," Taylor Man, chief technology officer of NTT Com Asia.

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

Other data centers in Hong Kong that have acquired LEED certification include HSBC Building Shek Mun Data Center (LEED Platinum), PCCW Kwai Chung Data Centre (LEED Platinum), HKEX Data Centre (LEED Gold), Equinix HK1-IX (LEED Gold), Equinix HK2-II (LEED Gold) Equinix HK3-II (LEED Gold) and Pacnet - EAC1 Data Centre Facility (LEED Gold).

Attaining full 21 points in energy optimization

The construction and operation of NTT Com FDC2 adopted the "Think Sustainability from the Project Start" approach. This approach provides the data center facility with a roadmap all the way from design, construction, operation to service delivery stage.

FDC2 adopted innovative design and technologies such as the Cooling Wall (front-flow cooling design with hot aisle containment) and Cooling Battery (a thermal energy storage system for data centers), with the ultra-high density design (which supports installation of ultra-tall racks up to 54U and power density up to 24kVA per rack). Consequently, FDC2 is said to have increased its cooling energy efficiency by over 20% and achieved a market-leading annualized PUE of below 1.5 at full-load.

On an annual basis, FDC2 successfully minimizes energy consumption to around 60%, following the ASHRAE Standards, resulting in 357,000 tons of CO2 emission reduction. These achievements helped NTT Com's FDC2 to attain the full 21 points under LEED-CS 2009 EAc1 Optimize Energy Performance.

"NTT Communications does not just position itself as a technology pioneer, but also a green advocate that is committed to adopting environmental-friendly design and best practices," Man said. "Moving forward, we will continue to contribute to a sustainable society by transforming our business and pioneering innovations that meet future society needs."
