Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

 


Driving Data Center PUE, Efficiency

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Bill Kosik.

"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."

Evaluating UPS System Efficiency

"Many modern uninterruptible power supply (UPS) systems have an energy-saving operating mode. Data show that very few data centers put it to use because of the potential risks."

Understanding Cogeneration Systems

http://www.csemag.com/single-article/understanding-cogeneration-systems/ebec65943f512c49199b852db0b51104.html

"Cogeneration systems—also known as combined heat and power (CHP) systems—generate both electricity and usable thermal energy. These systems typically are used on campuses that have high heat load requirements." Describes three CHP system prime movers: back-pressure steam turbine, combustion turbine, and reciprocating engine.

Implementing Microgrids: Controlling Campus, Community Power Generation

"Microgrids are subsets of the regional electrical grid that have the ability to operate independent, or “island,” from the local utility. Microgrids normally operate in parallel with the utility, but they can operate in an isolated mode when utility service is interrupted or providing poor power quality. The design and operation of microgrids are optimized around the needs of the specific end users they serve."

Is VRF Right for Your Next Project?

Consulting-Specifying Engineer, June 2015, by Amara Rozgus.

"Variable refrigerant flow (VRF) systems can be specified into a variety of buildings, especially those that require flexibility. An overview of these systems and some best practices have been provided by Julianne Laue, PE, LLED AP BD+C, BEMP, senior energy engineer at the Center for Energy Performance, Mortenson, Minneapolis."

"Improved efficiency and safety, lowered costs and maintenance."

Case Study: Working Example: Zero Net Energy Center

High Performing Buildings, Summer 2015, by Michael Hummel and others.
http://www.hpbmagazine.org/attachments/article/12211/15Su-Zero-Net-Energy-Center-San-Leandro-CA.pdf

"To prepare electrical apprentices for working in the sustainable building industry in Northern California, the Zero Net Energy Center is a working example of an emerging phenomenon. The International Brotherhood of Electrical Workers Local Union 595 (IBEW) and the Northern California Chapter, National Electrical Contractors Association (NECA) created a world-class learning environment for apprentices to gain hands-on experience with cutting-edge technology and electrical systems. The ZNEC also addresses the need to repurpose the existing building stock in the U.S. by transforming a typical 1980s suburban office building into a modern net zero energy showcase. "

Case Study: From Darkness to Light: Engaging Employees to Save

High Performing Buildings, Summer 2015, by Scott Bowman and Carey Nagle.
http://www.hpbmagazine.org/attachments/article/12210/15Su-Iowa-Utilities-Board-and-Office-of-Consumer-Advocate-Des-Moines-IA.pdf

"Moving from a cave-like warehouse to an environment filled with daylight represented a dramatic shift for employees of the Iowa Utilities Board and Office of Consumer Advocate (IUB/OCA). Employees jumped on board with the energy-efficiency efforts, giving up comforts such as individual coffee makers, and opening and closing windows as needed to operate the natural ventilation system. An integrated design that maximizes passive strategies provides significant energy savings, but employee cooperation, especially involving plug load reduction, has proven key to reaching and maintaining performance goals.

The Ins and Outs of Revolving Doors: Factors to Consider When Specifying the Right Door

Construction Specifier, July 2015, by Glen Tracy.
http://www.constructionspecifier.com/the-ins-and-outs-of-revolving-doors/

"The built environment is an energy-guzzler. The U.S. Green Building Council (USGBC) states in this country alone, buildings account for 41 percent of energy use, 73 percent of electricity consumption and 38 percent of all CO2 emissions, and 13.6 percent potable water consumption. Globally, buildings use 40 percent of raw materials, or about 3 billion tons annually. Fortunately, the type of doors we select can have a big impact on a building’s energy profile."
