Absorption Chillers For Institutional Occupancies

Engineered Systems, Feb. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/97567-absorption-chillers-for-institutional-occpancies

"It's not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success."

The Internet Shouldn’t Run on Dirty Energy

Harvard Business Review, Dec. 16, 2015, by Nate Springer and Kelly Gallo.
https://hbr.org/2015/12/the-internet-shouldnt-run-on-dirty-energy

"The internet may seem to exist in the ether, but its plumbing includes a vast network of data centers, also known as server farms, which need power to function. In 2010, data centers represented 2% of all electricity use in the United States. Globally, it equates to 2% of all annual emissions linked to climate change. While that amount may not sound like much, it is almost equivalent to the impact of shipping all goods around the world each year. If the world is to become ever more efficient and reach global climate goals, internet power will need to play its part."

12 Ways to Save Energy in Data Centers

"This column provides both data center novices and experts some sense for the impact hardware and software has on data center design. And, it highlights the importance of software's current and future full load profile in a data center."

Driving Data Center PUE, Efficiency

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Bill Kosik.
http://www.csemag.com/single-article/driving-data-center-pue-efficiency/4bba5f95667a596a898be854d101e01e.html

"For the last decade, power usage effectiveness (PUE) has been the primary metric in judging how efficiently energy is used in powering a data center. PUE is a simple energy-use ratio where the total energy of the data center facility is the numerator, and the energy use of the information technology (IT) systems is the denominator."

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

HPAC Engineering, Mar. 2015, by DANFOSS.

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.
http://bookstore.ashrae.biz/journal/download.php?file=2015Mar_064-071_TechAward_Griffin.pdf

"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.
http://www.csemag.com/single-article/energy-performance-in-mission-critical-facilities/7d86458cbe2b48298e30ce1daaf36f5d.html

"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.
http://www.businessenergy.net/DE/Articles/Big_Data_Small_Generator_28480.aspx

"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."
