Most of the university's retrofits have used T8 fluorescent lamps. The physical plant staff is retrofitting many 32-watt T8s on campus with 28-watt versions, and certain spaces in older facilities now feature 28-watt T5s. One of Eaddy's challenges is keeping up with advancing technology — deciding when to specify the newest product and when to be content with a product that — after one year or less — already is considered obsolete.
"We're constantly fighting that animal, and we're trying to make the most practical sense of the implementation," he says. "We may be a cycle or two behind because it may not make total business sense for us."
In deciding whether to specify the newest products on the market, Eaddy looks at three primary considerations:
Along with installing more efficient T8s, the university uses a variety of lighting-control technologies. One of the most effective systems in place is a programmable breaker control system, Eaddy says.
"With a campus with varying ages of facilities, (it) was a good system that could interface with pretty much everything that we have out there — old, new, and in between," he says.
That system, along with another that controls relays and circuits, help lighting systems perform optimally. To ensure that optimal performance continues, front-line technicians need to have the necessary skills to maintain the equipment. Manufacturers of lighting systems and other building components will come to the university and work with its electrical services shop, the largest and busiest group in the department. Key personnel will work with technicians to make sure they understand equipment performance and required maintenance.
"If there are problems they encounter out in the field, there's follow-up by the manufacturer, on-site as well as over the phone, to address those concerns," Eaddy says.
