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.

 


Intelligent Efficiency & Continual Commissioning: Data Points

American Council for an Energy-Efficient Economy, Apr. 22, 2016, by Ethan Rogers.
http://aceee.org/blog/2016/04/intelligent-efficiency-continual

"One of the more vexing challenges for those in the energy efficiency program sector is ensuring that savings resulting from the implementation of an efficiency measure persist over time. Fortunately, a solution exists: intelligent efficiency can prevent the degradation of energy savings, and in some instances increase savings over time."

Should we Promote Heat Pumps to Save Energy and Reduce Greenhouse Gas Emissions?

American Council for an Energy-Efficient Economy, May 4, 2016, by Steven Nadel.
http://aceee.org/blog/2016/05/should-we-promote-heat-pumps-save

"In order to examine which applications are good for obtaining cost-effective energy savings from heat pumps, ACEEE conducted a pair of analyses that we are releasing today. One addresses opportunities to replace electric resistance heat with heat pumps and the other addresses replacing gas furnaces with heat pumps."

"The HVAC system at 350 Mission [San Francisco] aims for top marks in both energy efficiency and occupant satisfaction."

Data Centers and Ab/Adsorption Chillers

Engineered Systems, Apr. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/97665-data-centers-abadsorption-chillers

"A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation."

Next Step Homes Phase 1: Savings Validation

Northwest Energy Efficiency Alliance, Apr. 21, 2016.
http://neea.org/docs/default-source/reports/next-step-homes-phase-1-savings-validation.pdf

"The Northwest Energy Efficiency Alliance is leading a regional effort called Next Step Homes. The program encourages the design and construction of homes that are capable of achieving energy efficiencies significantly greater than required by current code. Energy 350 conducted a savings validation study for the 12 homes constructed in Phase I of the program."

Measuring the True Costs and Benefits of Energy Storage, Part 2

North American Clean Energy, Mar/Apr 2016, by Katherine Von Burg.
http://www.nacleanenergy.com/articles/22680/measuring-the-true-costs-and-benefits-of-energy-storage

"Part Two - How cycle life and environmental factors impact LCOE
In last month’s issue, Part One of this series began covering how checking a few simple performance metrics can help calculate the true costs and benefits of competing energy storage systems. Additionally calculating this levelized cost of energy (LCOE) can help distinguish between what might look like a good price up front from what’s actually a better buy in the long run."

Tuthill Optimizes Vacuum and Blower Systems for Food Plants

Blower & Vacuum Best Practices, Apr. 2016, by Clinton Shaffer.
http://www.blowervacuumbestpractices.com/industries/food/tuthill-optimizes-systems-vacuum-and-blower-food-applications

"Several experts from Tuthill recently spoke with Blower & Vacuum Best Practices Magazine to discuss opportunities for improvement regarding vacuum and blower systems at food manufacturing facilities. During the talks, Adam Crampton, Russ Ristow, and Tim Wilson of Tuthill covered a variety of topics—from the design basics of pneumatic conveying systems, to advanced vacuum optimization opportunities within packaging machines."

Maximizing MWh: A Statistical Analysis of the Performance of Utility-Scale Photovoltaic Projects in the United States

Lawrence Berkeley National Laboratory, Mar. 2015.
https://emp.lbl.gov/sites/all/files/lbnl-1004374.pdf

"This paper presents the first known use of multi-variate regression techniques to statistically explore empirical variation in utility-scale PV project performance across the United States."

Sewage Treatment Plant Retrofits Diffusers to Cut Energy Consumption 50%

Blower & Vacuum Best Practices, Apr. 2016, by Doreen Tresca.
http://www.blowervacuumbestpractices.com/industries/wastewater/sewage-treatment-plant-retrofits-diffusers-cut-energy-consumption-50

"In 2012 when the plant was struggling to keep up with regulatory requirements, the Ilmajoki STP [Finland] was using 4000 kWh per day. Once the new diffusers and control systems were implemented, the plant was able to reduce their consumption and averages to under 2000 kWh per day."
