Energy Newsbriefs

Articles for December 16, 2013

ENERGY NEWSBRIEFS is a weekly current awareness service provided by the WSU Extension Energy Program Library and written by Angela Santamaria, WSU Energy Library Manager, to assist users in tracking developments in the energy field. To view past issues or to subscribe to receive an email notification of the publication of a new issue, go to the Energy Newsbriefs home.

EC Motors, Explained” was written by George Riker, Market Development Engineer at ebm-papst Inc. EC (Electrically Commutated) motors are compared with the more traditional AC motor. EC motors can be quieter and more efficient. There are other differences in terms of size, voltage dependencies, speed control, protection, output, and more.


Performance Anxiety,” by Peter Fairley, was posted December 2013 on the Architectural Record website. There is increased pressure on building modelers to produce results that more accurately predict how a building will meet expected performance goals.

Prologis Rolls Out Its Warehouse Energy Retrofits” is a three-Web-page, November 2013 fact sheet from the Building Technologies Office (BTO) at the U.S. Department of Energy (DOE). The partnership of Prologis and DOE, with technical assistance from NREL (National Renewable Energy Lab), resulted in the improved lighting performance of an existing warehouse in Mississippi.

Following are two case studies from the Building Technologies Office (BTO) at DOE’s Energy Efficiency & Renewable Energy (EERE) Office; both were published October 2013

  1. "Bay Ridge Gardens - Mixed Humid Affordable Multifamily Housing Deep Energy Retrofit: Annapolis, Maryland” explains how 43% energy savings were achieved with the application of easy (“non-invasive”) retrofits.
  2. "Steam System Balancing and Tuning for Multifamily Residential Buildings: Chicago, Illinois” shows the energy savings (10.2%) that can be achieved with a simple payback of a little over five years when attention is given to balancing the amounts of steam entering the building’s radiators.


The following five articles were published in the November 2013 issue of Pumps & Systems; note that all five are two Web-pages in length:

  1. "Efficiency is a Primary Goal in AODD Pumping” was written by Tony Carden, Tuthill Corporation. It well describes the successful designs that have produced higher efficiencies in AODD (air-operated double diaphragm pump) pumping.
  2. "Life-Cycle Cost Analysis of Industrial Pumps,” by Anusuya Ramadoss, of Beroe, explains that the LCC (life-cycle cost) of industrial pumps far exceed (by a factor of five) their initial cost and the cost of their installation. As a result, firms with “matured procurement division” are paying attention to LCC in their procurement decisions and are decreasing LCC at various points in the lives of their pumps.
  3. "Metering Pump Reduces Chemical Costs While Improving Safety & Efficiency” was authored by Russell Merritt, Watson-Marlow Pumps Group. The metering pump is a technology adopted (early) by Lakehaven Utility District, in Washington State, for its wastewater treatment plant.
  4. "Optimized Performance in Industrial Wastewater Treatment,” by Greg Kriebel at Fluid Dynamics, explains, in detail, the three steps in the treatment process.
  5. "Using a Torque Wrench to Apply Stress to a Gasket,” by Michele Lincoln, describes the three types of torque wrenches (beam, clicker, and electronic) and the importance of working within the recommended torque ranges to achieve the appropriate stress.


"Fall and Winter Energy-Saving Tips" is a Web page from the U.S. Department of Energy. The site is now offering many tips for energy savings for the cooler months.
