Meeting this challenge raises questions regarding the code requirements, how other aspects of system design are compromised and what constitutes compliance. The new requirements for selective coordination of emergency and legally required standby systems in Sections 700.18 and 701.27 of the 2005 National Electrical Code (NEC) are challenging electrical engineers to intensively consider how systems respond to short circuits. Hospitals SeptemA Critical Look at Selective Coordination Increasing technology adoption also is driving growth, especially in such sectors as the healthcare market, where medical professionals are turning to computers and other digital devices to both boost efficiency and meet new regulatory requirements. Products are being developed for every network-infrastructure element, from cooling systems to server racks, and monitoring capabilities are being enhanced. The report, "North American Three-Phase UPS Market," from industry analysts at Frost & Sullivan, notes that UPS companies are, in many cases, acting as system integrators and even providing outsourced power-quality management services to corporate customers. Technology advances are driving rising electricity demands, which, in turn, are stressing current generation, transmission and distribution infrastructures-making technology users even more dependent on UPS protection, report authors state. Uninterruptible power supply manufacturers are among the few winners in today's uncertain electricity-supply environment according to a new report that sees UPS producers' annual revenues rising 38% by 2012.

"There's also a tangible reduction in electrical demand peaks (KW), lower maintenance hassles and lower costs whenever long-life lighting products are applied."
Lubinski, president of Ohio-based energy consulting firm Think Energy Management, LLC, a consultant to HEI. "We've helped the hotel hit a 50% improvement on kilowatt savings alone," says Richard G. The hotel cut wasteful spending on energy for lighting over 50% by simply replacing outdated incandescent and fluorescent lamps with dimmable, long-life plug-in and screw-in compact fluorescent lamps, high-efficiency T8 linear fluorescent lamps and electronic ballasts.

The people must also have a level of knowledge and understanding of building design, construction, operations, and maintenance as they relate to the total building commissioning process.ĭeveloped with input from APPA, Building Commissioning Association, Illuminating Engineering Society of North America, National Environmental Balancing Bureau, Sheet Metal and Air Conditioning Contractors’ National Association, Testing Adjusting and Balancing Bureau, and the University of Wisconsin- Madison, the program is the fourth in ASHRAE’s suite of certification offerings. The program recognizes that people who manage the commissioning process need to have people- and project-management skills. The program helps building owners, developers, operators, and others recognize individuals capable of assuring that building systems and equipment are designed, installed, tested, operated, and maintained according to their operational needs.
Just as the commissioning process helps buildings and their systems operate optimally, ASHRAE’s newest certification recognizes those with optimal knowledge of the entire building commissioning process.ĪSHRAE’s Commissioning Process Management Professional launches in June at the Society’s 2009 Annual Conference in Louisville, Ky.
