Over 50% Energy Savings Realized for Naval Air Station Facility on Whidbey Island

Northwest Energy Efficiency Council (NEEC) News, May 26, 2015.
http://www.neec.net/news/over-50-energy-savings-realized-naval-air-station-facility-whidbey-island

"The Naval Air Station (NAS) on Whidbey Island believes that national defense and environmental protection must be compatible goals. Their recent effort to develop and execute a targeted plan for upgrading the chilled water system serving their critical Naval Facilities Engineering Command (NAVFAC) facility is another great example of the commitment the NAS has for environmental stewardship and continual improvement."

Medical Data Center Controls Uptime, Energy With Variable-Frequency Drives

A "From the Field: Design Solutions" column, provided by the manufacturer, Danfoss.
"At a medical data center in the upper Midwest, cooling-system uptime reliability is ensured with redundant computer-room air-conditioning (CRAC) units. For example, in a room needing eight units, 10 are employed. Drives cut energy use 40 percent by controlling HVAC fan speed on CRAC units."

2015 ASHRAE Technology Awards: Data Center Economizer Efficiency

ASHRAE Journal, Mar. 2015, by Brett Griffin.

"The Digital Chicago Datacampus took advantage of efficiency improvements made possible by improved server equipment thermal tolerances, which open up the opportunity to condition a data center space without mechanical cooling for significant portions of the year in a wide range of climates."

Energy Performance in Mission Critical Facilities

Consulting-Specifying Engineer, Mar. 2015, by Bill Kosik.

"Mission critical facilities, such as data centers, are judged carefully on their energy use. Engineers should focus on the codes and standards that dictate energy performance and how building energy performance can be enhanced."

Big Data, Small Generator: The Future of Data Centers is Big Green

Business Energy, Mar.-Apr. 2015, by Mark Scott Lavin.

"Whether it’s a building filled with racks of managed cloud servers, a small colocation facility for local enterprises, or an Internet giant’s showcase IT installation, a data center is a complex and hungry beast."

Microsoft Experiments with Taking Energy-Sucking Data Centers Off the Grid

EnergyWire, Feb. 24, 2015, by David Ferris.

"At a lab in Southern California, Microsoft is trying out a radically different way to power the data center, one of the most energy-hungry kind of buildings there is. The solution is fuel cells, thousands of them, everywhere in the building, embedded into a rack of computer servers or even plugged into the individual servers themselves. In this way, Microsoft imagines it might be able to cut the cord entirely from the electricity grid."

Amazon Will Support 150 MW Indiana Wind Farm to Power the Cloud

Utility Dive, Jan. 22, 2015, by Robert Walton.

"In November 2014, AWS [Amazon Web Services] shared a long-term commitment to achieve 100% renewable energy usage for its global infrastructure footprint. The company called the power purchase agreement (PPA) backing the Fowler Ridge facility 'an important step toward that goal'."

Will Liquid Cooling Solutions Save Energy? [Data Centers]

Engineered Systems, Jan. 2015, by Terry Rodgers and Vali Sorell.
http://www.esmagazine.com/articles/96928-will-liquid-cooling-solutions-save-energy

"Many of the liquid cooling solutions hitting today’s market still require air-to-liquid heat exchangers that provide air cooling at the individual rack where the electronic equipment is housed. The IT hardware chassis include integral fans to move the cool air through the inside of the hardware chassis to move the heat from the electronics to the air within the cabinet (or rack). Technically, this is still air cooled hardware. We have reduced the range of cooling technologies available to five distinct scenarios, and then added three additional scenarios that are becoming available (though not widespread) at this time. These scenarios will each be analyzed individually to quantify what energy efficiencies (or inefficiencies) are inherent for each."

HP Supercomputer at NREL Garners Top Honor

National Renewable Energy Laboratory (NREL) Feature News, Oct. 13, 2014.
http://www.nrel.gov/news/features/feature_detail.cfm/feature_id=15403

"A supercomputer created by Hewlett-Packard (HP) and the Energy Department's National Renewable Energy Laboratory (NREL) that uses warm water to cool its servers, and then re-uses that water to heat its building, has been honored as one of the top technological innovations of the year by R&D Magazine."
