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.

 


Designing for Comfort & IAQ: Air Distribution per ASHRAE 55 and 62.1

The Construction Specifier, June 2014, by Jim Aswegan and David Pich.
http://www.constructionspecifier.com/masterformat/designing-for-comfort-iaq-air-distribution-per-ashrae-55-and-62-1/

"The goal of a room air distribution system is to provide thermal comfort and a healthy living environment for occupants in the space. American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) 55-2013, Thermal Environmental Conditions for Human Occupancy, and ASHRAE 62.1-2013, Ventilation for Acceptable Indoor Air Quality, provide designers with the guidance to optimize health and comfort in building spaces. Many codes, along with the U.S. Green Building Council’s (USGBC’s) Leadership in Energy and Environmental Design (LEED) 2009 program, require compliance with these ASHRAE Standards."

The Next Generation of U.S. Energy Efficiency Motor Regulations

Pumps & Systems, Jun. 2014, by John Malinowski.

"Several years ago, the U.S. Department of Energy (DOE) conducted a technical study about how to raise “small” motors’ efficiency levels. After years of study, the Small Motor Rule was passed, covering General Purpose two-digit NEMA frame (and IEC equivalents), single- and three-phase, 1/4- through 3-horsepower motors in open enclosures. Totally enclosed, fan-cooled (TEFC) motors are not included. This regulation will take effect on April 9, 2015."

Grounding Rings Rescue Paper Mill’s Bearings

Maintenance Technology, May 2014.

"At a paper mill in the Midwest, every new motor that is to be controlled by a variable frequency drive (VFD) must be tested. If shaft voltages are found, the motor must be equipped with an AEGIS® Bearing Protection Ring to divert damaging currents to ground. The plant’s electrical reliability engineer established this money-saving specification after many years of frustration from recurring bearing failures."

Eccentric Disc Pumps Create Product Recovery Cost Savings

"Targeted product recovery in hygienic manufacturing reduces waste, decreases operating costs and maximizes the use of raw materials and end products."

Effect of the Type of Bean, Processing, and Geographical Location on the Biodiesel Produced from Waste Coffee Grounds

Energy Fuels, 2014, by Rhodri W. Jenkins, et. al.
http://pubs.acs.org/doi/pdf/10.1021/ef4022976

"Waste coffee grounds offer a viable waste feedstock for biodiesel production. Approximately 8 million tonnes of coffee are produced globally each year and contain up to 15 wt % lipid, of which the glyceride portion is predominantly made up of palmitic, stearic, oleic, and linoleic acids. In this investigation, the variation in the oil content, saponifiable lipids, and lipid profile according to the regional location and processing or brewing techniques was assessed. A number of key fuel properties were also investigated."

"The pumping operation experienced an 80-percent reduction in energy use."

Same Treatment Quality, Less Energy [Wastewater]

Treatment Plant Operator, Jun. 2014, by Doug Day.

"A Mississippi plant copes with high flows from two poultry plants with a new SCADA system and automated control over dissolved oxygen.... After the first year of operation, Parker found the plant’s annual electricity use had dropped by 12.5 percent (21,500 kWh)."

Why Owning Your Own Power Plant Might Not Be Crazy

RMI Outlet, Rocky Mountain Institute, May 2014, by Leia Guccione.
http://blog.rmi.org/blog_2014_05_22_owning_your_own_power_plant

"...it’s not that far-fetched to imagine a day when large segments of customers choose to go mostly or even entirely off-grid with clean, quiet, distributed solar-plus-battery systems. In fact, could owning your own power plant become as convenient and practical—if not quite as ubiquitous—as the consumer appliances and electronics already so commonplace that we take them for granted in our daily lives—a refrigerator, a clothes dryer, or a computer?"

Heat Pumps Designed to Save Energy

Air Conditioning, Heating, Refrigeration News, May 26, 2014, by Joanna R. Turpin.
http://www.achrnews.com/articles/126690-heat-pumps-designed-to-save-energy

"The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well, thanks to the growing demand from building owners and managers, who are looking for ways to save energy."
