Report on occupancy sensors released
The Dept. of Energy has released a report comparing experiences from field installations of occupancy sensor-controlled LED lighting in parking structures and found an additional 76% in energy savings after they made the switch to LEDs.
The U.S. Department of Energy (DOE) has published a GATEWAY demonstration report that summarizes and compares experiences from field installations of occupancy sensor-controlled LED lighting in two parking structures and two parking lots. Occupancy sensor systems are gaining traction as an effective approach to reducing energy use, and can potentially enhance the savings from an already efficient lighting system. However, this technology also faces challenges that can leave a significant amount of the prospective savings on the table.
The relative levels of success at these sites reflect a broad range of potential outcomes—from an additional 76% in energy savings (after those gained by the initial conversion to LED) to virtually no additional savings. Several key issues influenced the results in these early stage installations, including products not adequately designed to withstand full exposure to the environment, installation designs not sufficiently optimized for the individual site, and overlapping control systems. The report emphasizes the need to carefully examine the selection of equipment, and its integration into a coordinated system, to maximize performance while minimizing inconvenience and negative effects on users of the space.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
