"Multiple Boiler Option: When and How to Use Hybrid Systems," by Mark Norris, Academy Instructor, Viessmann, appeared in the March 2013 issue of HPAC Heating, Plumbing, Air Conditioning Magazine. In some situations where multiple boilers are needed, a hybrid boiler system may be the right choice. The author explains when it is advisable to rely on a non-condensing boiler, which is cheaper than a condensing boiler. He, further, describes how to properly pipe and control a hybrid system.
"Advantage America: The U.S.-China Clean Energy Technology Trade Relationship in 2011" is a 36-page, 2013, report from the Pew Charitable Trust. In the Executive Summary (scroll to document-page 4), it is stated that the clean energy trading between the U.S. and China is only a fraction of the half-trillion-dollar annual trade between them, but that, nonetheless, the clean energy trading is important and, often, misunderstood. Currently, the U.S. has an annual trade surplus in each of all three major areas studied: PV, wind, and energy-smart technologies. The total trade surplus for the U.S. for the three is $1.63 billion. The report cautions that uncertain, clean-energy policy in the U.S. translates into more negative weight on the trade surplus than anything else. The Pew website, also, carries a press release, issued March 6, 2013, describing the study.
"Scaling Up Multifamily Energy Efficiency Programs: A Metropolitan Area Assessment" (free registration may be required to view document), by Kate Johnson and Eric Mackres, is a 105-page, March 2013, report from ACEEE (American Council for an Energy-Efficient Economy); it includes an Executive Summary on document-page iii (PDF-page 5). ACEEE makes the case for targeting multifamily homes (those having five or more family units) with programs tailored specifically to them.
"Pumps and Power," by Paul Hull, is a three-Web-page article carried in the March 2013 issue of Water Efficiency. The author addresses the need for energy efficiency whether for temporary or permanent pumping operations and mentions that 95% of all the power used by water utilities is to run the pumps. He explains how the EUI (energy use index) is a helpful measure of consumption, suggests how to select the right pumps for the specific application, and considers the role motors play in pumping efficiencies.
The following two articles were published in the March 2013 issue of Pumps & Systems:
- "Design Software Increases Hydraulic Efficiency" was written by Arno Gehrer, Ph.D., Research Engineer Andritz Group. The author describes, with illustrations, how a company that designs and builds both custom and standard pumps for various large-scale applications has greatly improved both processes.
- "New Optimized Aeration System Reduces Energy Consumption" was authored by Lars Larsson, Global Product Manager, Biological Treatment, for Xylem, Inc. Increases in energy prices and higher quality standards for effluent are squeezing water treatment plants to take a new look at their processes. A municipal plant in southern Sweden has done just that and installed new, energy-efficient equipment to achieve dramatic energy savings.
RENEWABLES – FEDERAL SITES
Developing Renewable Energy Projects Larger Than 10 MWs at Federal Facilities: A Practical Guide to Getting Large-Scale Renewable Energy Projects Financed with Private Capital is a 74-page, March 2013, guidebook from the Federal Energy Management Program (FEMP); it was written by Robert Springer of NREL.
RESIDENTIAL EFFICIENCY STRATEGIES
"Spring and Summer Energy-Saving Tipsv" is a Web page from the Energy Efficiency and Renewable Energy Office of the U.S. Department of Energy. The site offers many tips for energy savings for the warmer months.
The following three articles were carried in the March 2013 issue of Wind Systems:
- "Build It, Bond It, Fix Itv" by Jason Spencer, Business Manager for Adhesive Technologies, Michael Gansow, Ph.D., Manager for PUR Adhesive Development, and Thomas Buckley, Market Application Engineer; all of Henkel Corporation. The author discusses adhesives, sealants, lubricants, and coatings and how they are used for wind turbines. The article includes a sidebar, "Polyurethane Adhesive Technology for Rotor Blade Bonding."
- Construction," by Julian Bell, Director of Preconstruction for Signal Energy Constructors, cautions that paying attention to the construction budget and schedule and to the maximizing of power generation at the expense of safety and quality issues will surely and negatively impact all three.
- "Maintenance" was authored by Jack Wallace, Director of Wind Turbine Technical Services for Frontier Pro Services. He suggests that costly condition monitoring equipment (CME) will, in the end, save money. Vibration CME, he continues, yields the data the maintenance team needs to get maintenance right and without costly guesswork.
