Designed to save millions of gallons of water and increase energy efficiency by up to 50 percent

liebert-dse-mediumColumbus, Ohio [September 16, 2015] – Emerson Network Power, a business of Emerson, (NYSE: EMR) and the world’s leading provider of critical infrastructure for information and communications technology systems, today announced that the California Energy Commission (CEC) has approved the use in California data centers of the Liebert® DSE thermal management system with the Liebert EconoPhase Pumped Refrigerant Economizer. The Liebert DSE system represents a break-through technology that uses no water and saves up to 50 percent of thermal energy, through its patented design and advancedLiebert iCOM™ controls.  

“The Liebert DSE system is a great environmental steward. When used in a typical mid-sized data center of one megawatt load, the Liebert DSE is significantly more efficient than current cooling systems, and eliminate the use of around four million gallons of water each year. If deployed broadly in California data centers, the Liebert DSE with EconoPhase could save hundreds of million gallons of water every year,” said John Peter Valiulis, vice president North America marketing, thermal management, Emerson Network Power.
 
The CEC has approved the Liebert DSE system with Liebert EconoPhase as a prescriptive economization option, as part of Title 24 of the the CEC’s 2103 Building Energy Efficiency Standards For Residential and Non Residential Buildings, meeting the code’s requirements for energy efficiency and its prescriptive requirements for economizers.
 
The Liebert DSE system eliminates the need for any water in the heat rejection process and associated chemical water treatment, and it eliminates the risk of exposure to harmful waterbound bacteria. In addition, the Emerson modeling for the CEC compliance program demonstrated an 8 to 10 percent reduction in the data center Time Dependent Valuation measure, compared to the water economizer prescriptive option. The Liebert DSE system design also reduces or eliminates several of the power components associated with water economizers. In actual usage, the entire Liebert DSE system has demonstrated thermal system energy savings of up to 50 percent over older legacy systems.

New NFPA Electrical Safety Rules Mean Changes for Your Data Center

A service professional is working on a piece of electrical equipment. He’s done it hundreds of times before, but in a moment of carelessness or by total accident, an arc flash occurs. Most of us think this couldn’t happen to us. The truth is that electrocutions are the fourth leading cause of traumatic occupational fatalities, and according to the American Society of Safety Engineers, more than 3,600 workers suffer disabling electrical contact injuries annually.

LEED Silver Data Center

NTT: Taking the LEED lead in Hong Kong

NTT Communications now operates Hong Kong’s first LEED:EBOM certified data center. Taylor Man, NTT Com Asia’s Executive Vice President for New Business, explains why the standard is becoming so important for the country’s data center industry.

The focus on Corporate social responsibility (CSR) by governments, regulators and increasingly customers is driving sustainability in the data center sector. And market volatility, focus on expenditures and rising operational costs has further led to demands for process efficiency, the streamlining of operations and lower energy usage.

While operating right at the heart of bustling at the heart of bustling Hong Kong, NTT Communications started to look for ways of being more ‘green’. We found the answer with LEED:EBOM, the Leadership in Energy and Environmental Design standard issued by the Green Building Council for Existing buildings, Operations and Maintenance).

NTT became the first data center in Hong Kong to receive LEED Silver certification EBOM for its Hong Kong Data Centre after proving large energy savings due to efficiency measures. The data center is in a seven-floor building, which covers 212,000 sq ft that was launched in 2009. It provides high-availability services and has been built to handle mission critical environments, with a Tier III infrastructure.

Do You Prefer Hot Aisle or Cold Aisle Containment?

by Mike Rinaldi on 8/7/12 3:13 PM

Separating the hot and cold air in a data center is one of the keys to improving energy efficiency.  Containment systems don't have to be fancy or expensive.  Containment systems have been in use at least since 2004, but there's an ongoing debate about whether it is best to contain the hot aisle or cold aisle.  

Do you use containment in your data center?  If so, do you contain the hot aisle or cold aisle?"
