"Compressed air audits for chemical and petrochemical plants have many characteristics in common with audits in other industries, but there are some differences in the way these businesses run that impact the goals of the typical audit and how that audit is conducted. In chemical and petrochemical facilities, the reason for auditing the demand side is different than that of other industries."

Solar Gardens: A Fast-Growing Approach to Photovoltaic Power

"How to give electricity customers who can’t take advantage of rooftop solar access to the sun? Community solar—a shared resource—is a fast-growing segment of the renewable energy market, making solar photovoltaic power more accessible while offering another approach to distributed generation."

Centrifugal Air Compressor Basics: Deciphering Manufacturer Performance Curves

Compressed Air Best Practices, May 2015, by Hank van Ormer.
http://www.airbestpractices.com/technology/air-compressors/centrifugal-air-compressor-basics-deciphering-manufacturer-performance-cu

"In general, this article focuses on the operating principles of centrifugal air compressors, discussing them in simple terms to provide an understanding of application limitations and opportunities. One primary goal is to define often-confusing terminology, such as 'rise to surge,' 'stonewall and surge,' 'mass flow,' and 'dynamic compression.'"

Uncovering the Cost Benefits of a Good Lighting Circuit Design

"Iterative voltage drop calculations are some of the most tedious and time-consuming components of an electrical design process. This is especially true for large lighting installations, such as those found in parks and parking lots as well as roads and highways. As a result, it is common for designers to oversimplify voltage drop calculations in a lighting design. With the lighting industry trending toward LED use, it is becoming increasingly common to string large quantities of luminaires on a single circuit due to the decreased load per luminaire. Now more than ever, detailed voltage drop calculations can avoid over engineering of lighting systems and substantially decrease project costs."

LEDs Still a Mystery to Many Contractors

"As LED products continue to flood the marketplace, electrical contractors must balance the appeal of online buying expedience with the need to fully grasp a technology still shrouded in uncertainty. Held up as one of the proven, readily deployable technologies that could put a big dent in global energy consumption over time, LED lighting products are drawing the interest of ever more electrical contractors looking for avenues into the lucrative and growing energy-efficiency market."
