First LEED platinum data center built in Germany

Citigroup's new data center is the first in the world to receive USGBC LEED platinum, and the first LEED-certified building in Germany.


Citigroup 's new data center in Frankfurt, Germany, has been awarded for maximizing sustainability without losing reliability, according to Environmental Leader . The 230,000-sq-ft building, designed by Arup Assocs. , is the first data center in the world to be awarded U.S. Green Building Council LEED platinum and the first building in Germany to achieve LEED accreditation.

The data center's energy-efficient design was combined with energy-efficient virtualized technology in a modular design that optimized energy use and reduced the total length of cabling by 150 miles. It also includes an enhanced computer room air conditioner that reduces power consumption from 9.3 to 3.3 kW/unit and an advanced cooling tower design that cuts power consumption from 74 to 22 kW. The data center will use only 30% of the power and 40% of the heating energy needed for a conventional data center, and have a free cooling rate of 63%.

Water-efficient fixtures reduce potable water use by 41%. A reverse osmosis water treatment system for cooling will save the building 13.2 million gal annually. The building also uses harvested rainwater for all of its irrigation needs. During construction, all waste was diverted from the landfill, and recycled content of the materials reached 27% with local sourcing of materials exceeding 40%, a representative at Citi said.

Citi representatives said the sustainable design was achieved with no increased cost over conventional data centers and without sacrificing reliability and resilience of the systems. The new building sets new standards in sustainable design , set to bring about dramatic changes in the way that energy-hungry data centers are designed and built in the future.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
