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.

 


SEPA Report Details Key Drivers for Cutting Utility-Scale Solar LCOE

Smart Electric Power Alliance, Mar. 2016.
http://www.solarelectricpower.org/about-sepa/sepa-news/press-releases/sepa-report-details-key-drivers-for-cutting-utility-scale-solar-lcoe.aspx

"...a new report from the Solar Electric Power Association (SEPA) says, not all solar projects are created equal. Utilities looking to procure cost-competitive, high-value solar projects need to evaluate a range of factors, from regional solar resource intensity to local labor and permitting costs to system design issues, such as whether to use a fixed-tilt or single axis tracking system. The report was produced in partnership with solar project developer Recurrent Energy, a subsidiary of Canadian Solar."

Solar Panels Could Ruin Your Roof

Buildings, Feb. 2016, by Douglas Fishburn.

"Modern continuous monitoring technologies are streamlining maintenance programs and improving plant operations."

Reinventing Green Building—It’s (Past) Time

Heating, Piping, Air Conditioning Engineering, Feb. 2016, by Jerry Yudelson.
http://hpac.com/archive/reinventing-green-building-it-s-past-time

"The major green-building rating system in the United States, LEED, or Leadership in Energy & Environmental Design, is not growing. As of 2015, LEED’s 15th year, less than 1 percent of commercial buildings and homes in the United States were LEED-certified.... Concerns about LEED are not new, but they have taken on more urgency with the mandatory switch to a new version of LEED (LEED v4) in October 2016."

Absorption Chillers For Institutional Occupancies

Engineered Systems, Feb. 2016, by Marcia Karr.

"It's not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success."

Innovative Blow Molds Reduce Compressed Air Pressure in PET Blow Molding

Compressed Air Best Practices, Mar. 2016, by Vincent Duvernois,  Stephane Larcade, and Jean Pilnard.

"Technological trends in plastics manufacturing are driving the costs of production down. In industrial PET blow molding specifically, two innovative techniques have had major impacts over the last 15 years: “light weighting” the plastic bottles, and recirculating high-pressure compressed air. Both have helped to improve the energy efficiency of PET blow molding by reducing compressed air requirements dramatically."

Electric Motor Efficiencies and VFD Compatibility

ASHRAE Journal, Feb. 2016, by David A. John.

"When consulting engineers select and specify fans for HVAC systems, they often specify that the motor for a fan should be a premium efficiency motor. this is critical because most variable frequency drives (VDs) require a premium efficiency motor."

Field Evaluation of Advances in Energy-Efficiency Practices for Manufactured Homes

National Renewable Energy Laboratory, Mar. 2016.
http://apps1.eere.energy.gov/buildings/publications/pdfs/building_america/65436.pdf

"Through field-testing and analysis, this project evaluated whole-building approaches and estimated the relative contributions of select technologies toward reducing energy use related to space conditioning in new manufactured homes. Three lab houses of varying designs were built and tested side-by-side under controlled conditions in Russellville, Alabama. The tests provided a valuable indicator of how changes in the construction of manufactured homes can contribute to significant reductions in energy use."

Combined Heat and Power (CHP) Technical Potential in the United States

U.S. Department of Energy, Advanced Manufacturing Office, Mar. 2016.
http://energy.gov/sites/prod/files/2016/03/f30/CHP%20Technical%20Potential%20Study%203-18-2016%20Final.pdf

"This study provides data on the technical potential in industrial facilities and commercial buildings for “topping cycle” CHP, waste heat to power CHP (WHP CHP), and district energy CHP in the U.S. The report provides valuable data on the technical potential for CHP in strategic energy planning and energy efficiency program design. The study shows that within the U.S. there is estimated to be more than 240GW of technical potential at over 291,000 sites. Data is provided nationally by CHP system size range, facility type, and state."

Engine Block Heaters: Quick Starts for Standby Power

Forester Daily News, Mar. 14, 2016, by Penelope B. Grenoble.
http://foresternetwork.com/daily/energy/energy-conservation/engine-block-heaters-quick-starts-for-standby-power/

"...whether you call them block heaters, water jacket heaters, or engine preheaters, they’re essential to getting diesel-fueled gen sets up and running at full power in the 10 seconds that are standard for emergency power applications."
