Energy Newsbriefs Blog

The WSU Energy Program Library prepares this current awareness blog with funding from the U.S. Department of Energy State Energy Program. These articles highlight energy-related news, articles, and reports about energy efficiency, energy conservation, and renewable sources of energy for energy professionals and interested members of the public.


Choosing a Pump for the Total System

Pumps & Systems, May 2017, by Ray Hardee.
http://www.pumpsandsystems.com/pumps/may-2017-choosing-pump-total-system

"In this two-part series, we will look at a simple system consisting of a collection tank, a pump, distribution tank and the interconnecting piping as shown in Figure 1. This simple system is often used for distribution of water, bulk materials transfer, industrial waste collection and agricultural irrigation."

Vacuum System Fundamentals for “Compressed Air People”

Blower & Vacuum Best Practices, April 2017, by Tim Dugan.

"If you want to understand vacuum systems, you have to get out of the ruts, and slog through the mud and bounce over the rocks a bit.  If you’re a “compressed air person”, think outside the box for a few pages with me.  I am going to borrow some terms from the “pump people” to explain how vacuum systems are similar, yet different from compressed air systems. There are several ruts to get out of.  Remembering what changes and what doesn’t, what is controlled, and how to design systems for optimal energy consumption."

The Heart of Pneumatic Conveying Systems – Positive Displacement Blower Calculations

Blower & Vacuum Best Practices, April 2017, by Roger E. Blanton.

"The heart of the pneumatic conveying system (air mover, solids feeder, pipeline, and separator) is the air mover. Correctly specifying the volumetric flow rate and pressure levels required to move the material will determine system reliability.  One must also look at pipe size, distance, and the weight of the material being moved. A company specializing in the design requirements of pneumatic conveying systems is best consulted for evaluating these requirements and specifying the required air or gas flow rate for the system."

Designing with Tunable White Light

National Lighting Bureau, 2017 Lighting Forum Video.
https://nlb.org/designing-with-tunable-white-light/

"One of the most important applications for tunable white light will occur in health-care facilities, especially for patients dealing with dementia and Alzheimer’s Disease. By using light as a stimulant during morning hours, patients will nap less during the day, enabling them to sleep better at night. Using light in this way can also reduce the patients’ agitation. In commercial applications, tunable white light can be used to affect the colors of surfaces in a space. This gives building owners the ability to provide lighting that is highly compatible with a given tenant’s interior design, and to adjust the lighting to make it ideally suited for the next tenant’s interior design, avoiding the need to replace the existing system for each new tenant."

Utilities Choose to Embrace Distributed Energy Future…or Ignore at Their own Peril

"A new report by the Deloitte Center for Energy Solutions points out what most industry leaders have known for a while—that consumers are increasingly interested in clean energy choices and perhaps even going off the grid to gain them. The company’s 2016 report cited statistics showing that 65 percent of residential customers are “very concerned” about the environment and their impact on it, coupled with the cost of wind, solar and battery storage falling 41, 54 and 73 percent, respectively, since 2008, according to federal indicators."

OSHA Standard 29 CFR 1019.134 Grade D Compressed Breathing Air Requirements

Compressed Air Best Practices, May 2017, by Nancy Aulisa.
http://www.airbestpractices.com/standards/nfpa-99-medical-air/osha-standard-29-cfr-1019134-grade-d-compressed-breathing-air-requirem

"Compressed air, commonly called Industry’s fourth utility, is the most common utility used in a typical industrial facility. Compressed air is used in more than 70 percent of all manufacturing activities including supplying breathing air to personnel using supplied air respirators. Hazardous breathing conditions exist in many routine industrial operations, such as chemical manufacturing, hospitals, abrasive blasting, paint spraying, industrial cleaning, and arc welding. In these and other operations that introduce contaminants into the workplace, supplied-air respirators, air filtration systems and carbon monoxide monitors are frequently used for worker protection."

Making Sense of Compressed Air at a Huge Chemical Plant

Compressed Air Best Practices, May 2017, by Don van Ormer.
http://www.airbestpractices.com/industries/oil-gas/making-sense-compressed-air-huge-chemical-plant

"A chemical plant spends an estimated $587,000 annually on electrical energy to operate their compressed air system. In addition, the plant has an expenditure on rental air compressors of equal or greater size - but this will not be covered in this article. The plant was built in the 1940s and modernized in the 1970s. The plant generates its own power and serves many processes. The average cost per kWh is $0.0359."

New Developments in Museum Lighting Design

The Construction Specifier, Apr. 2017, by Scott Newman.
https://www.constructionspecifier.com/new-developments-in-museum-lighting-design/print/

"Museums employ two key strategies for lighting works of art: daylighting and artificial or electric lighting. For the Whitney Museum of American Art in New York City, architects Cooper Robertson and Renzo Piano Building Workshop collaborated extensively with Arup consulting engineers, as well as museum curators and conservators, to design suitable solutions for both imperatives."

Optimizing Centrifugal Chiller Systems

Engineered Systems, Apr. 2017, by Chris Miller.
http://www.esmagazine.com/articles/98238-optimizing-centrifugal-chiller-systems

"Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned."
