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.


Pond Loop for Ice Refrigeration

ASHRAE Journal, Sep 2015, by Jason Larosh.

2015 ASHRAE Technology Award Case Studies:
"The pond loop geothermal refrigeration system at the Janesville Ice Arena uses an adjacent pond as thermal storage to pull heat from and reject heat to the ice sheet refrigeration system. Other improvements to the arena include a new ice sheet and hot water heating system."

City Sewage Energy Recovery

North American Clean Energy, Jul/Aug 2015, by Erwin Schwartz B.Eng. is the President at DDI Heat Exchangers.

"Municipal wastewater heat recovery is a system in which a heat exchanger transfers heat energy from the sewer waste water to a solution of water and antifreeze (ethylene glycol). A heat pump then uses the heat of this solution to heat buildings, preheat domestic hot water, and heat garages in the winter and also cool the space in the summer."

The Good News On Renewables — Unleashing Innovation: Energy Report

iBloomBerg Reports, Sept. 14, 2015.

"In February 2013, California energy officials sat down with power-industry executives to figure out how to avert an approaching calamity: The rapid rollout of wind and solar electricity was stressing the state’s grid. The more renewable energy California added, the more its power supply could be whipsawed by a cloudy day or a windy storm. Some at the meeting warned that problems, such as rolling brownouts, could start to show up later that year. ...Plenty of risks still remain. But the fact that the grid has been able to handle more renewables than previously thought is driving massive changes through the industry. One of the places it is being felt most acutely is among utilities."

US Foods Opens 6th LEED-Certified Distribution Center

Refrigerated & Frozen Foods, Aug. 24, 2015.

"US Foods, Rosemont, Ill., opened its sixth LEED-certified distribution center in Flowood, Miss. The new 272,000-square-foot facility was built after the original location was destroyed by a tornado last April. It will service more than 4,000 chefs, restaurant owners and foodservice operators throughout Mississippi and Louisiana. [The facility] includes a number of green enhancements, such as energy efficient lighting, dedicated fleet fueling and maintenance area and a cascade refrigeration system that uses CO2 as a refrigeration fluid in place of ammonia."

Pacific Northwest Residential Ventilation Effectiveness Study

Northwest Energy Efficiency Alliance, Sept. 14, 2015, by Ken Eklund and others.

"This report presents the findings and conclusions of the Pacific Northwest Residential Ventilation Effectiveness study in houses with low air leakage. The Northwest Energy Efficiency Alliance (NEEA) commissioned the Washington State University (WSU) Energy Program to conduct the study, which included a total of twenty-nine houses in Washington State with five different types of ventilation systems. Exhaust ventilation (Exhaust Only (EO) and Exhaust with Inlet Vents (EI)) and heat recovery ventilation (HRV)/energy recovery ventilation (ERV) systems made up the largest share of the ventilation systems studied."

NFL Stadiums Attempt to Lower Energy Costs: 24 of the Most Energy Efficient Stadiums in the League

Electric Choice, Aug. 21, 2015.

"With the National Football League’s pre-season in full swing, and regular season play right around the corner, football fans from all over the country are gearing up to see their favorite teams square off. Every season, millions of fans pile into NFL Stadiums to watch the action unfold live. These stadiums are notorious for their size and technological advancements. They also consume millions of kilowatt hours in energy."

Combination Ductless Heat Pump & Heat Pump Water Heater Lab and Field Tests

Northwest Energy Efficiency Alliance (NEEA), Aug. 26, 2015, by Energy 350.

New NEEA Report: "This report summarizes the lab and field test findings for Mitsubishi’s prototype Ductless Heat Pump (DHP) Plus H2O product. This product combines a ductless heat pump with a heat pump water heater into a single, integrated product. Mitsubishi has teamed with a water heater partner for the water heater portion of the product. NEEA has partnered with Mitsubishi to test the appliance and to provide feedback regarding performance. NEEA has selected Energy 350 to conduct the testing and reporting."

2014 Wind Technologies Market Report

U.S. Department of Energy, August 2015.

"According to the 2014 Wind Technologies Market Report, total installed wind power capacity in the United States grew at a rate of eight percent in 2014, bringing the United States total installed capacity to nearly 66 gigawatts (GW), which ranks second in the world and meets 4.9 percent of U.S. end-use electricity demand in an average year. In total, 4,854 MW of new wind energy capacity were installed in the United States in 2014."

Specifying Acoustical Ceilings in Green Buildings

The Construction Specifier, Aug. 2015, by Kenneth P. Roy.

"Until now, acoustics in commercial office buildings had not been a formal part of the Leadership in Energy and Environmental Design (LEED) rating systems except on a case-by-case basis. The new LEED v4 criteria, however, now takes into account the value of good acoustics in enhancing occupant satisfaction and productivity."

It's All About the Data: How the Building Performance Database is Informing Decisions on Energy Efficiency

U.S. Department of Energy, Aug. 25, 2015.

"Filling a gap in the market, the BPD provides public access to anonymized data on hundreds and thousands of buildings and homes.  Increased access to energy-related information in buildings allows end-users to make key decisions on energy efficiency projects, policies and programs. For the first time, users can compare variables across regional markets, uncover data trends, and draw conclusions that would otherwise be impossible or costly to identify."
