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.

 


For Better Or For Worse...R-22 RIP (Part 3)

Heating, Plumbing, Air Conditioning, Feb. 2014, by Dave Demma.
http://www.hpacmag.com/news/for-better-or-for-worse-r-22-rip/1002910208/

The first two articles in the series discussed the importance of having an R-22 refrigerant replacement strategy, help in choosing a replacement, and the process of implementing the conversion. 

This 3rd and final article in the series discusses how "a detailed plan can be assembled to ensure the conversion is completed in a minimum amount of time, and the result is a system that operates efficiently and trouble free."

NREL Aims to Improve Building Energy Performance with New Web-Based Tool

National Renewable Energy Laboratory (NREL), News Release NR-1314, Mar. 4, 2014.
http://www.nrel.gov/news/press/2014/8311.html

"The Energy Department’s National Renewable Energy Laboratory (NREL) has developed a web-based tool to help consumers better understand the energy performance of building-related products. The Technology Performance Exchange™ (TPEx™) is a portal that helps manufacturers and other organizations that measure and test products easily share performance data with product consumers."

Restoring The Low Limit For Indoor Relative Humidity

Engineered Systems, Feb. 2014, by Gary L. Berlin.

"Industry leaders realized hundreds of years ago that their processes and machines operate best when the indoor relative humidity is maintained at an optimum level for their process. They found it was necessary to use energy to increase productivity, lower scrap and environment impacts, maintain profits, and maintain costs to their customer. It does not matter if their process is related to food, woodworking, textiles, printing, pharmaceuticals, electronics, automotive, laboratories, or maintaining and preserving artifacts in museums and libraries. Controlling the indoor humidity was and is still critical for their applications."

Problems Found In The Field: How Retrocommissioning Can Solve Them

Engineered Systems, Feb. 2014, by Scott Blackman and Michael Falkenstern.

"The symptoms are familiar: hot and cold complaints, higher-than-expected costs, etc. Here’s a look at how the retrocommissioning process should work to tackle these and other developments for your facility."

Storage Steps Up: Could Grid-integrated Batteries Change the Way Power Producers Operate Fossil Power Plants?

Fortnightly's Power Profit, Feb. 26, 2014, by Scott M. Gawlicki, Public Utilities Fortnightly.

"Duke Energy Renewables’ 153-MW Notrees (Texas) Wind Power Project includes a 36-MW advanced lead acid battery – the largest capacity battery facility in North America. Duke says developing expertise in this advanced technology will help expand the use of renewable energy, better integrate it into the power grid, and make the company more efficient at serving customers. Could batteries and other storage technologies affect the way power producers evaluate and operate their generating assets – in particular fossil fired generating assets they currently rely on to supply ancillary services?"

Seawater Warms Up Marine College Building

Engineered Systems, Feb. 2014, by Rob Klinedinst and David Reinheimer.

"In its latest effort in an ongoing program to green its campus in South Portland, Southern Maine Community College (SMCC) turned to an innovative way to heat and cool one campus building: seawater.

Tapping into nearby Casco Bay, the seawater-based system uses a variable refrigerant flow (VRF) configuration with geothermal heat pumps to heat and cool the 3,250-sq-ft Lighthouse Building, which houses the school’s arts program and offices for The Foundation for Maine’s Community Colleges."

Trends in Industrial Motors and Drives

Design News, Feb. 2014, by Al Presher.

"New motor and drive systems are continuing to focus on several main design goals: more intelligent performance, higher energy efficiency, and flexible integration options. The result is macro trends that are putting increased focus on support for a broader set of motor types, advanced cooling options, and built-in safety features, along with tighter integration of motor-drive solutions and decentralized control."

Wind Proves it Can Hold Its Own in Tough Times

Wind Power Monthly, Feb. 2014, by David Milborrow.
http://www.windpowermonthly.com/article/1228422/wind-proves-hold-its-own-tough-times

"The increasingly competitive position of wind as an electricity-generating source has been highlighted in Windpower Monthly for some time, but in 2013 a number of influential international organisations, such as the International Energy Agency and the World Energy Council, also reflected this view. The exact position of wind vis a vis cost comparison varies, depending on the price of competing fuels, but the debate over the relative economics of wind and nuclear power has acquired clear evidence over the past 12 months that wind is cheaper than nuclear."

New Refrigeration Efficiency Standards To Take a Bite out of Supermarket and Restaurant Energy Costs

American Council for an Energy-Efficient Economy (ACEEE), Feb. 28, 2014, by Joanna Mauer.
http://aceee.org/blog/2014/02/new-refrigeration-efficiency-standard

"The Department of Energy (DOE) issued a final rule for strong new efficiency standards today that will take a big bite out of the energy consumption of the refrigerators and freezers used in supermarkets, convenience stores, restaurants, and commercial kitchens. The significant reductions in energy use that we’ll see with the new standards are made possible by the availability of technologies including LED lighting and occupancy sensors, high-performance glass doors, and high-efficiency motors, which all provide big efficiency gains." Includes a link to the final rule.

Is Your Building Conducive to the Installation of a Green Roof?

EDC: Environmental Design + Construction, Feb. 2014, by Richard Heller and Chris Psencik.
http://www.edcmag.com/articles/95450-is-your-building-conducive-to-the-installation-of-a-green-roof

"Despite the potential, installing a green roof is not a decision to be taken lightly. There are several structural and site/location considerations to take into account. The most recent news of a probable green roof collapse at a Latvian supermarket should give one pause. Before allocating the time and resources, facility owners and managers should weigh the pros and cons of a green roof and what to keep in mind during the planning stages."
