The Fine Art of Making Energy Visible

Business Energy, Jul/Aug 2014, by Mark Scott Lavin.

"One of the boldest experiments in energy efficiency collaboration in the US is now well underway in Vermont, where cold winters and other factors drive some of the highest energy costs in the country. It’s spearheaded by a new kind of utility known as Efficiency Vermont and run by the non-profit Vermont Energy Investment Corporation (VEIC). This new utility is the first of its kind, though similar initiatives have emerged in Oregon, Washington DC, and the Ohio region. Efficiency Vermont provides electricity to stakeholders, not by building power plants, but by helping existing consumers use less energy and use it wisely."

Customized Pumping System Brings New Efficiencies to Mineral Processing

Maintenance Technology, Aug. 2014, by Grundfos Engineered Systems (GES) team.

"Energy-efficient pumps, intelligent pump-control logic and variable-frequency drives help the company process more minerals and cut energy use."

Evaluating Air Compressor Cooling Systems

Compressed Air Best Practices, Aug. 2014, by Nitin G. Shanbhag.

"As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important."

Dealing With Motor Failures: Common Causes and Solutions

Maintenance Technology, Aug. 2014, by Thomas H. Bishop.

"If you want to make a plant manager’s day, just say: “Production’s down because a motor failed.” Fortunately, such situations can usually be overcome with some relatively simple techniques and straightforward solutions to protect the bearings and stator windings. These two vulnerable components are root causes of the vast majority of motor failures."

Case Study: Insulation Audit Leads to Big Savings [Chemical Plant]

Insulation Outlook, Aug. 2014, by Zach Tanghetti.

"Honeywell's Geismar site was established in 1967 and is currently operated by roughly 275 employees and 130 contractors. The site is responsible for producing multiple refrigerants, hydrofluoric acid, and a resin that is used in medical packaging. The various reactors, heat exchangers, steam traps, and process piping that make our processes a reality all utilize insulation to maintain temperatures and moderate processes. All of our processes are susceptible to inefficiencies because systems that include insulation can degrade in a chemical plant environment. When insulation degrades, it loses its ability to retain heat within the system. Though the site is in Louisiana, winters can still be cold, and steam and other process lines have even been known to freeze in the past. Improved repair and maintenance of insulation systems could have helped prevent these process upsets."

System Selection Crucial for Long Wastewater Pump Life

Pumps & Systems, Aug. 2014, by Lars Bo Andersen.

"Driving down investment, energy and maintenance costs translates into big savings throughout an installation’s lifetime."

A Different Approach to Understanding Power Factor

Pumps & Systems, Sep. 2014, by Joe Evans.
http://www.pump-zone.com/pumps-motors/september-2014-different-approach-understanding-power-factor-first-three-parts

"First of Three Parts - Power factor (PF) is an important component of an alternating current (AC) circuit, but understanding its actual effect can be difficult. Why is PF mysterious to many of us? It has to do with the way it is explained."

"WhiteWave Foods, Broomfield, Colo., announced green building certification of its beverage manufacturing facility in Dallas, Texas. The facility...earned U.S. Green Building Council (USGBC) LEED certification for New Construction."

Combined Heat and Power and Clean Distributed Energy Policies

American Council for and Energy-Efficient Economy (ACEEE), July 2, 2014, by Anna Chittum and Neal Elliott. (Free registration required to view full-text of report.)
http://www.aceee.org/policy-brief/combined-heat-and-power-and-clean-distributed-energy-poli

"Combined heat and power (CHP) systems generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but a particular way to deploy existing technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, so CHP systems are more efficient and provide environmental, economic, and energy system infrastructure benefits. However, several barriers impede cost-effective CHP applications, including lack of common interconnection protocols, discriminatory standby rates, and emissions regulations that do not recognize the improved efficiency levels of CHP systems."

Efficient Building Water Use

Consulting-Specifying Engineer, July 2014, by Willa Kuh and Fred Betz.
http://www.csemag.com/single-article/efficient-building-water-use/5c43e78511f4c18036dd0e018167ce82.html

"The escalating cost of providing potable water in the United States is creating new urgency for owners of commercial, industrial, and institutional buildings to respond with greater engineered water efficiency."
