Optimized Power-Demand Control System for Electric Motors

Heating, Piping, Air Conditioning Engineering, Mar. 2016, by Alexander L. Burd and Galina S Burd.

"During off-design load conditions, use of variable-frequency drives (VFDs) reduces electric-motor power demand. At design and near-design loads, however, it has the opposite effect. Widespread application of VFDs, then, might cause an increase in the design power demand of electric utilities, forcing them to administer mandatory consumer power-demand-shedding programs. An increase in design power demand over installed power capacity might lead to other negative consequences, such as electric-utility power outages, consumer productivity losses, and increased environmental pollution. This article demonstrates how automatic switchover from VFD control mode to VFD-bypass control mode and back can help to mitigate, if not eliminate, these negative impacts."

This Earth Day, Let’s Look at How Much Energy We’ve Been Using

American Council for an Energy-Efficient Economy, Apr. 22, 2016, by Rachel Cluett.

"Earth Day was first celebrated in 1970, and that got us thinking about how households used energy back then. What did they use it for? Do we follow the same conventional wisdom for saving energy in our homes today, even though there are some obvious differences in the types of devices we use now?  We were curious to dig in and see how energy use has changed over the past 35+ years, and how that change shapes our efforts to conserve."

FM Alert: ASHRAE, AIA Look To Future Of Energy Efficiency

Facility Executive, Apr. 2016.
https://facilityexecutive.com/2016/04/ashrae-aia-look-to-future-of-energy-efficiency/

Green Building Report: Energy Benchmarking Ordinances

Building Operating Management, Mar. 2016, by Jenny Carney.
http://www.facilitiesnet.com/energyefficiency/article/What-You-Need-To-Know-About-Energy-Benchmarking-and-Disclosure-Ordinances--16501

"The spread of energy benchmarking and disclosure ordinances across the U.S. has been one of the more interesting developments around sustainability and existing buildings. But the ordinances themselves aren’t the whole story. Along with those regulations is a growing array of programs and tools that can help facility managers make the most of benchmarking by improving the energy efficiency of their buildings."

Rooftop Refrigeration Unit Performance

ASHRAE Journal, Apr. 2016, by Kenneth M. Elovitz.
http://bookstore.ashrae.biz/journal/download.php?file=2016Apr_034-043_Elovitz.pdf

"Diagnosing a rooftop air-conditioning equipment performance problem requires analyzing complete refrigeration system performance data. The systematic approach described in this article resulted in replacing orifice-type metering devices with a traditional thermal expansion valve—and remedying insufficient dehumidification."

A Simple Approach to Affordable GSHPs

ASHRAE Journal, Apr. 2016, by Steve Kavanaugh and Chris Gray.
http://bookstore.ashrae.biz/journal/download.php?file=2016Apr_014-025_Kavanaugh.pdf

"Conventional wisdom says ground source heat pumps (GSHPs) should not be considered for commercial and institutional buildings because of the added cost. This article investigates how building owners leasing the ground heat exchanger can make GSHPS affordable for commercial and institutional applications."
