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.

 


Why Your High-Efficiency-Lighting May Not Be Very Efficient At All

National Lighting Bureau News, July 14, 2015.
http://www.nlb.org/index.cfm?cdid=11138&pid=10213

"Silver Spring, MD: Imagine, if you will, the world’s most efficient lighting system; a system so efficient that it provides all the lighting needed by a 100-person workforce for  the fantastically small sum of just $100 per year; that’s $1 per person per year. Can a lighting system be any more efficient than that? Yes, it can, says National Lighting Bureau Chair James M. “Jim” Yorgey, P.E., LC, CTS: “While having a highly efficient lighting system is important, it’s even more important – from a bottom-line point of view – that the lighting system contribute to the enhanced efficiency of other systems that are affected by lighting, human systems in particular.”

Landmark Northwest Study Reveals Smart Grid Pros and Cons

"A recently completed $178-million Pacific Northwest Smart Grid Demonstration Project led by Battelle demonstrated that smart grids are more efficient and resilient, according to a project report. The demonstration project was the largest of 16 smart grid demonstration projects funded by the U.S. Department of Energy under the American Recovery and Reinvestment Act of 2009. The effort encompassed more than 60,000 metered customers, many of them served by public power utilities in Idaho, Montana, Oregon, Washington and Wyoming."

Riding Off into the Sunset: Nuclear Decontamination and Decommissioning Update

Power Magazine, July 2015, by Aaron Larson.
http://www.powermag.com/riding-off-into-the-sunset-nuclear-decontamination-and-decommissioning-update/

"The International Energy Agency predicts that nearly 200 reactors will be decommissioned during the next 25 years. Industry best practices and new technology can help make the process go more smoothly.

It may not come as a surprise, but the average age of operating reactors in the U.S. is greater than 35 years. There hasn’t been a new nuclear reactor brought online in the U.S. since 1996, but there have been five permanently removed from service in the past three years. Although many plants have had their original 40-year operating licenses extended an additional 20 years, that hasn’t stopped some plants from facing permanent shutdown due to economic and other reasons.

3 Options for HVAC Energy Savings

Building Operating Management, June 2015, by James Piper.
http://www.facilitiesnet.com/hvac/article/3-Options-for-Energy-Savings-in-HVAC-Systems-Facilities-Management-HVAC-Feature--15949

"Even with today’s falling energy prices, facility managers are looking for ways to reduce the energy use of HVAC systems. New technologies and improvements in existing technologies are giving facility managers options. While advances can be seen in practically all HVAC systems, some of the most significant advances are coming in three particular areas: variable refrigerant flow systems, rooftop units, and geothermal systems."

Driving Data Center PUE, Efficiency

"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

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Paul Barter and Edward T. Borer.
http://www.csemag.com/single-article/implementing-microgrids-controlling-campus-community-power-generation/1ebe5e9f6874b762fca56287475b4a2d.html

"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?

"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."
