The following two articles were published in the April 2013 issue of that Building Design + Construction:
- " 'My BIM journey' – 6 Lessons from a BIM/VDC Expert" was authored by Jared Krieger, AIA, LEED AP, Gensler. Good advice is offered on how to get the most out of building information management (BIM) systems.
"Small but Mighty: Berkeley Public Library's Net-Zero Gem" was written by David Barista, Editor-in-Chief, Building Design + Construction. This is a case study of a library whose designers hope to achieve net-positive-energy performance, that is, the annual generation of more onsite energy than needed
"Coming into Their Own," by Penelope B. Grenoble, was published in the March/April issue of Distributed Energy. When large swaths of the population are without power because of hurricanes and the like, microgrids, with fuel cells powered by natural gas might come to the rescue.
"Navy, NREL Conduct Office Energy Study to Reduce Power Use" is a brief article, published in the May 15, 2013 issue of EERE Network News. It discusses the collaboration of the U.S. Navy's Naval Facilities Engineering Command Hawaii and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) to reduce the Navy's energy consumption. The effort includes an upcoming report about an April 2013 demonstration project related to energy data collection. The article includes a link to each of two press releases on the subject, one from the Navy and the other from NREL.
The following three articles were published in the April 2013 issue of Pumps & Systems:
- "Optimize Pump System Maintenance Budgets" is two-Web-page article by Dan Kernan, ITT Industrial Process. It is based on the author's October 2012 webinar presentation. The article demonstrates how an appropriate maintenance strategy will result in a smoother and less expensive maintenance experience. It will, also, reduce the frequent emergency repairs that can stall production.
- "Precision Lubrication Enhances Pump Reliability" is a two-Web-page article by Jarrod Potteiger of Des-Case Corporation. The author defines "precision lubrication," cautions against lubrication precision maintenance programs that are not designed properly, and explains, in good detail, how to proceed to ensure pump reliability.
- "Renewable Power with Rotary Lobe Pumps," was written by Marino Curati of Vogelsang and Sandra Walker of Zeropex U.S. This is a discussion of how replacing pressure reducing valves at water utilities with rotary lobe pumps can, in effect, produce power. As added benefits, this power may be considered renewable and its production may reduce the plant's carbon footprint.
RESIDENTIAL EFFICIENCY STRATEGIES
"Spring and Summer Energy-Saving Tips" 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.
"Solar Impulse Plane Lands in Phoenix" is short news article, posted on the BBC News website's "Science & Environment" page about the flight of the Solar Impulse, an experimental plane that runs on solar.
"Navigating the Complexities of Wake Losses," by Katy Briggs, was published in the April 2013 issue of North American Windpower. Just as boats leave wakes, a wind turbine can generate a wake that reduces the power generation of turbines downwind. Wake losses are of major concern in trying to assess the amount of wind available to generate power. However, the author cautions against relying on wake-loss models because wake losses are very complex and extremely difficult to estimate. Wake-loss models currently in use, almost necessarily, lack accuracy.
The following three articles were carried in the April 2013 issue of Wind Systems:
- "Cross-Technology Drivetrain Lubrication," by Daryl Luke, Global Product Manager at Castrol Industrial, discusses lubricants for the gearbox systems which transmit blade power into electricity for most of the wind turbines in operation today.
- "Making Sense of the CMS Market" was written by Brogan Morton, Product Manager for TurbinePhD, of NRG Systems. Conditioning monitoring systems (CMS) discover faults in turbines before they become major problems. The wind farm owner faces the problem of determining which CMS to purchase. The author provides information which should help.
- "Managing Drivetrain Health: Knowledge Is Power, Time Is Money" was authored by Larry Jacobs, Marketing and Sales Manager, North America, for Romax Technology. Once the CMS is selected and in place, the data it produces must be understood and used.
