New Fluorescent Lamp Rules to Shake Up T8 Category

Lighting Management & Maintenance (LM&M), Aug 2105, by Craig Delouie. (Scroll to page 24.)

"In January 2015, DOE announced new energy standards for general-service fluorescent lamps, which will take effect January 26, 2018. The new rules strengthen energy standards for 4-ft. T8 linear and 2-ft. T8 U-bend, while both strengthening and expanding covered wattages for 4-ft. T5 and T5HO linear lamps. Eight-foot lamps did not see any change."

Cool Advice On Hot Motors

Maintenance Technology, Aug. 2015., by Jim Bryan.

"The effects of excessive temperature on motor performance are notorious. After moisture, they are the greatest contributor to bearing and winding failures. Understanding the source of increased temperature is key to correcting the problem and improving the reliability of your facility’s motor fleet."

Validate Sealing Systems for Optimized Performance

Pumps & Systems, Aug 2015, by Larry Castleman.

"Sealing systems can play a vital role in equipment performance and are considered critical components in the validation process of a design. Engineers should closely examine the sealing systems used in their equipment, because they do everything from preventing seal leakage and extending hydraulic cylinder life to lowering dynamic friction and controlling hydraulic motor position."

Optimize High-Energy Pumps With Improved Impeller Design

Pumps & Systems, Aug 2015, by Bob Jennings & Dr. Gary Dyson.

"The rising cost of electrical power has caused many industrial plants to shift their focus to energy consumption. Plants often run pumping equipment continuously, and much research has pointed to opportunities for cost savings by optimizing pumping equipment. When evaluating the potential for energy savings, end users cannot consider a pump in isolation. The suitability of the pump for the system within which it operates is vital. Even the best designed and most efficient equipment offers power-saving potential if it is run off its best efficiency point (BEP) in a system for which it is ill-applied."

Balancing Software Conserves Energy in Multiple-Pump Systems

Pumps & Systems, Sep. 2015, by Kurt Bihler.

"Each adjustable speed drive can find its own set point independently without stressing the entire system. Process control through traditional adjustable speed drives (ASDs) with centrifugal pumps has an inherent problem of attempting to use a linear equation to solve a non-linear problem. Common ASD controller software provides an estimated speed to achieve a desired set point. But when the target speed is reached with this method, the set point is not available because the answer is on an unknown non-linear curve."

US Foods Opens 6th LEED-Certified Distribution Center

Refrigerated & Frozen Foods, Aug. 24, 2015.

"US Foods, Rosemont, Ill., opened its sixth LEED-certified distribution center in Flowood, Miss. The new 272,000-square-foot facility was built after the original location was destroyed by a tornado last April. It will service more than 4,000 chefs, restaurant owners and foodservice operators throughout Mississippi and Louisiana. [The facility] includes a number of green enhancements, such as energy efficient lighting, dedicated fleet fueling and maintenance area and a cascade refrigeration system that uses CO2 as a refrigeration fluid in place of ammonia."

Blades & Rotors [Turbines]

Business Energy, Jul/Aug 2015, by Carol Brzozowski.{}

"Savings and reliability from turbines and microturbines."

Saving Water with Cooling Towers

ASHRAE Journal, Aug 2015, by Frank Morrison.

"Saving water with cooling towers. At first glance, this statement seems counterintuitive. Cooling towers save energy but aren’t they major users of water? This article will help readers understand the critical role evaporative heat transfer systems play in a sustainable environment, explore how water is consumed in such systems, and review the strategies that help minimize the use of both water and energy."

Troubleshoot Hot Hydraulics

Maintenance Technology, July 2015, by Jane Alexander.

"High oil temperatures in industrial hydraulic systems can lead to a world of hurt. Don’t let them get you down."

Manufacturing Energy Efficiency

ASHRAE Journal, July 2015, by Charles E. Gulledge III, and others.

2015 ASHRAE Technology Award Case Studies: Caterpillar Tractor Assembly Plant, Athens, GA.

"Realizing energy use reductions at Caterpillar’s heavy manufacturing complex required optimization of multiple component and system solutions. Iterative analysis was used to determine project-responsive configurations."
