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.

 


EnergyIQ™: Action-Oriented Energy Benchmarking

Lawrence Berkeley National Laboratory.
http://energyiq.lbl.gov/

"In isolation, benchmarking can inspire action but provides no practical guidance. With sponsorship from the California Energy Commission's Public Interest Energy Research (PIER) program, the U.S. Department of Energy's Lawrence Berkeley National Laboratory is building the next generation of energy benchmarking methods to address this problem. EnergyIQ—the first "action-oriented" benchmarking tool for non-residential buildings—bridges this gap by providing a standardized opportunity assessment based on benchmarking results, along with decision-support information to help refine action plans."

Vacuum Steam Heating: Past, Present...Future?

District Energy, Fourth Quarter, 2014, by Igor Zhadanovsky.

"Every so often, a technology that had been abandoned for a long period of time comes back to life thanks to new developments that make it viable and competitive once again. While it's too early to predict with certainty, this may be the pattern that we see for one of the heating industry's oldest technologies: vacuum steam heating. This article describes the evolution of that technology, its benefits and drawbacks, and a new approach that may make it a cost-effective option in the 21st century.

Preparing for Distributed Generation in the Northwest

Northwest Public Power Association (NWPPA) Bulletin, Oct. 2014, by Charlie Black. (open PDF, then scroll or jump to page 26)

"In recent years, electric utility customers have begun showing greater interest in distributed generation. Declining costs and expanding availability of on-site electric generating systems, such as roof-mounted solar photovoltaic equipment marketed and installed by third-party service providers, are causing residential and business customers to consider self-supply as an attractive alternative to relying exclusively on centrally generated power delivered via the utility grid."

A Bright Future for Veterans [Armed Forces Retirement Home, DC]

Environmental Design + Construction (EDC), Oct. 2014.
http://www.edcmag.com/articles/95909-95909-a-bright-future-for-veterans

Excellence in Design Winners 2014:
"The AFRH New Commons Health Care Center, The Scott Building, located on the Old Soldier’s Home grounds in Washington, D.C., is a unique space that combines assisted living user needs, campus-wide program requirements, a historic site and environmental considerations into a multiuse facility. The AFRH Campus is home to more than 500 military veterans from all branches of the armed forces."

BIRDS Is for Sustainability: New NIST Tool for Evaluating Building Performance, Trade-offs

National Institute of Standards and Technology (NIST), Oct. 2014, by Mark Bello.
http://www.nist.gov/el/economics/20141007_birds.cfm

"Designing a building that simply meets local code requirements is not necessarily the optimal way to do it when you consider all the long-term costs. Now, building professionals in more than 200 U.S. cities can use a new database developed by the National Institute of Standards and Technology (NIST) to evaluate whether it pays to exceed code requirements for energy efficiency by tallying expected costs, kilowatts expended, carbon emissions and other impacts over a planned commercial building's lifetime. Called BIRDS (Building Industry Reporting and Design for Sustainability), NIST's new database and software tools are designed to assess three major determinants of building sustainability: energy, environmental and cost performance."

A Different Approach to Understanding Power Factor (Last of Three Parts)

Pumps & Systems, Nov. 2014, by Joe Evans.
http://www.pumpsandsystems.com/pumps/november-2014-different-approach-understanding-power-factor-last-three-parts

"Two methods can be used to improve PF with capacitors. Static correction involves using capacitors to correct a single load. They can be installed at several locations. Static correction can be the most effective method, but it can also be the most expensive. Bulk correction uses a bank of capacitors that improve PF for different parts of a facility. These capacitors can be switched in and out of the circuit depending on the monitored PF."

Future Solar Cost Reductions Hinge on Raising Solar Cell Efficiencies

Solar Industry, Oct. 2014, by Michael Puttre.
http://www.solarindustrymag.com/issues/SI1410/FEAT_01_Future-Solar-Cost-Reductions-Hinge-On-Raising-Solar-Cell-Efficiencies.html

"Lowering the levelized cost of energy (LCOE) of solar photovoltaic power is probably the No. 1 issue facing the industry. For most of the last decade, the focus of that effort has been reducing the costs of solar panels."

Efficiency Beyond Design: Energy Codes

Lighting, Electricity, Steel: Energy Efficiency Backfire in Emerging Economies

The Breakthrough, Oct. 6, 2014, by Ted Nordhaus and others.
http://thebreakthrough.org/index.php/issues/energy-efficiency/lighting-electricity-steel

"Countries that expect to consume much more energy will likely experience higher levels of energy efficiency rebound, concludes a new Breakthrough report, released today. Rebound is the phenomenon in which energy efficiency measures increase demand for energy, which diminishes expected energy savings. [This report] presents three historical case studies of when energy efficiency rebound occurred: lighting from 1700 to present, electricity generation in 20th century America, and iron and steel production from 1900 onward."

The Rebound Effect and Energy Efficiency Policy

E2e Working Paper 013, Oct. 2014, by Kenneth Gillingham, David Rapson, and Gernot Wagner.
http://e2e.haas.berkeley.edu/pdf/workingpapers/WP013.pdf

"What do we know about the size of the rebound effect? Should we believe claims that energy efficiency improvements lead to an increase in energy use? This paper clarifies what the rebound effect is, and provides a guide for economists and policymakers interested in its magnitude."
