This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

 


An Inside Look at Cradle to Cradle Certification

"Have you found that trying to purchase sustainable products could be a job in and of itself? When you really need to focus on energy and water conservation, it’s hard to find the motivation to assess a manufacturer’s green claims. After all, you’re not a toxicologist, chemist, or lab technician. What you really need is verification that a product was sourced and manufactured in a responsible way, has no exposure risks for occupants while in use, and has reclamation options that will save it from the landfill."

"Construction is nearing completion, and all the equipment is installed at CR&R Inc.'s high solids anaerobic digester (AD) facility in Perris, California. “We are approaching a dry run with the digester to test out the various system components, and then will fine-tune the process controls,” notes Paul Relis, CR&R Senior Vice-President. “We will likely start processing feedstocks in the digesters in the first quarter of 2016.”"

10 Little-Known VSD Air Compressor Tweaks

Compressed Air Best Practices, Nov. 2015, by Ron Marshall for the Compressed Air Challenge.
http://www.airbestpractices.com/technology/compressor-controls/10-little-known-vsd-air-compressor-tweaks

"The introduction of rotary screw air compressors controlled by variable speed drives (VSDs) is one of the best energy efficiency innovations introduced to the industry in the past few years. This style of compressor control can significantly reduce the energy wasted by compressors running in the unloaded condition. But the type of VSD control offered by various manufacturers can differ, and some of these differences can affect the efficiency of the system. This article discusses some little known tweaks to VSD compressor control, including some using hidden features that can sometimes be implemented to enhance the savings gained by the installation of this type of compressor."

Air Compressor Control for Industry 4.0

Compressed Air Best Practices, Nov. 2015, by Clinton Shaffer.

"We are in the midst of the fourth industrial revolution, or, as it is known in Germany, Industry 4.0. In broad terms, the concept describes manufacturing facilities where all of the machines — including the air compressors, along with their corresponding sensors and air treatment equipment — communicate with each other autonomously, recording performance metrics to a local controller, a wireless network, and an external database. These communicative abilities are enabled by the Industrial Internet of Things (IIoT), in which intelligent, networked devices link everything back to a main data hub."

Managing Multiple-Compressor Systems: Utilizing Controls to Improve Performance

Compressed Air Best Practices, Nov. 2015, by Chad Larrabee.

"An unmanaged control scheme for a bank of air compressors is a recipe for unnecessary consumption of power, as well as increased or unplanned maintenance. Controlling air compressors with only their on-board controllers can cause one or more of the following problems:
  • Too many compressors are running.
  • The wrong combination of compressors is running.
  • Pressure is higher than it needs to be."

WELL Building Standard Drives Global Growth of Healthy Building Movement
