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.


HVAC Codes and Standards: Cooling and Energy Efficiency

Consulting-Specifying Engineer, Aug. 2016, by Gayle Davis.

"Codes and standards dictate the design of HVAC systems; however, there are ways to improve the design of nonresidential buildings to achieve maximum energy efficiency."

Innovation Ups Irrigation IQ: Sensors, Controllers, and Flow Meters Get Smarter

Water Efficiency, Sep/Oct 2016, by Lyn Corum.

"All growers want to see their crops, gardens, and landscapes flourish. Competition among manufacturers of irrigation controllers, sensors, and flow meters is driving innovation at high speed in this digital age, to satisfy the market."

Is An LED Right For Your Next Retrofit Project?

Consulting-Specifying Engineer, Aug. 2016, by Tom Divine.

"As LED illumination technology improves in efficiency, reliability, and quality, building owners become interested in cost-effective ways to apply LED lighting in their facilities. In many cases, retrofitting existing fluorescent or incandescent luminaires will be an attractive alternative to wholesale fixture replacement. This article explores the effects of some of the applicable codes on LED retrofit projects."

German [Wastewater] Plant Upgrades Drop Specific Energy Use by More Than 50 Percent

Pumps & Systems, Sept. 2016, by Erkki Lantto & Stefan Wilken.

"In the city of Sögel, Germany, one municipal wastewater plant employs turbocompressors to reduce its operating costs and cope with load fluctuations. The setup’s success comes from an advanced design with proven magnetic bearing technology and a high-speed motor. The plant treats domestic wastewater and industrial wastewater from nearby food industry factories."

Energy Trust Tops 10,000 Energy Efficient Homes

Portland Business Journal, Aug. 16, 2016, by Jon Bell.

"Just 300 homes built in Oregon in 2009 had an Energy Performance Score, the energy performance rating tool developed by the Energy Trust of Oregon. In 2015, that number soared to 2,500 homes.As of this month, all of those numbers have helped Energy Trust surpass the 10,000 mark when it comes to homes rated with an EPS. According to the nonprofit, more than a third of new homes built in Oregon these days have an EPS."

Energy Secretary Moniz and Interior Secretary Jewell Announce New National Offshore Wind Strategy to Drive Deployment, Sept. 9, 2016.

"U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell today announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States, which could help enable 86 gigawatts of offshore wind in the United States by 2050. The strategy details the current state of offshore wind in the United States, presents the actions and innovations needed to reduce deployment costs and timelines, and provides a roadmap to support the growth and success of the industry."

Comparing Polystyrenes: Looking At the Differences Between EPS and XPS

The Construction Specifier, Sep. 2016, by Jason Burgess.

"Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS). Both serve the same basic function: providing a means to manage the passage of heat in a building system. However, they differ in important ways."

Benchmarking Boom

Building Operating Management, Sept. 2016, by Richard G. Lubinski.

"... a three-part article on best practices in energy benchmarking as more cities and states make it mandatory."

Pumping Prescriptions: What Happens to Power & Efficiency When a Pump Wears Out?

Pumps & Systems, Sept. 2016, by Lev Nelik.

"When a pump experiences internal wear, its performance drops. Flow is reduced and efficiency plummets. But what happens to power? Does it drop, stay the same or increase? The answer to this question depends on how a pump wears internally. In extreme cases, when the impeller is completely worn, there will be no flow and hardly any power. But in many cases, tight clearance parts, such as wear rings and bushings, are the first to wear."
