The Bartow County College and Career Academy (BCCCA) addressed lighting uniformity issues in parking lots and driveways with a lighting retrofit from Acuity Brands, Inc. Twenty-eight American Electric Lighting™ Autobahn LED luminaires were mounted to existing 30-foot aluminum poles, replacing 1,000-watt metal halide fixtures.
The town of Richmond Heights, Ohio, has a little more than 10,000 residents and a whole lot of financial problems. Luckily, Richmond Heights also has the solution to their troubles with LED lights. A solution that will save money they don’t have and increase public safety at the same time.
In 2012, the city’s bill for street and traffic lighting was over $118,000, and they were forced to come up with creative ways to save money. They tasked Police Chief Gene Rowe with the duty of personally turning off every other traffic light in town in an attempt to achieve some of the savings they needed. The chief systematically shut down the lights in a pattern of one on, one off throughout the small town. A total of 54 of the 122 traffic signals were turned off in this move to save money, which is a traffic nuisance and public safety danger to say the least. The total savings of the move amounted to a mere $26,000, leaving lots of fat to cut in the budget still.
There are numerous other advanced controls methods that can help facility managers squeeze even more savings out of their facilities’ lighting systems. They include the following:
• Light level tuning. Adds to energy savings by reducing lighting output at modest levels, undetectable to the human eye.
“Often design light levels are needlessly high, so reducing lamp output by 5 to 10 percent can bring energy savings benefits without compromising occupant satisfaction,” Renner says. Continue reading
Daylight is free, and many spaces inside buildings are daylit, yet electric lighting is left on unnecessarily. Daylight harvesting harnesses this free, natural light, using such building control system strategies as light sensing, occupancy sensing, and shade control, while automatically adjusting the energy use of HVAC and electric lighting systems.
The results? Reduced overall energy costs, coupled with healthy and productive working environments. Daylight harvesting technologies include photocells, occupancy sensors and centralized or distributed control systems. The strategy can be implemented during building design and planning or even retrofitted flexibly at a later time. Continue reading
For facility managers who have taken basic steps to reduce lighting system energy costs, the ability to wring savings out of lighting systems doesn’t end there.
Advances in technology continue to provide additional opportunities for savings. In fact, the average commercial facility could stand to do more than just basic upgrades to its outmoded lighting systems. Options run the gamut — including fixture replacement, daylighting, dimming, advanced control and ballast strategies.
“[A facility manager’s] best bet is to explore the different energy management strategies that are available,” says John J. Brelus, General Electric‘s global product general manager — fluorescent systems. Continue reading
Emergency LED lighting from GDS and its ArcSystem can become a functional and integral part of the house lighting system in public venues such as the Wembley Arena in London.
GDS (Global Design Solutions) has announced that the famed Wembley Arena in London now relies on 44 Arc eight-cell LED fixtures for emergency lighting. But the efficiency and functionality of solid-state lighting (SSL) will allow the arena to utilize the emergency lighting as a functional cog in the overall house lighting. Continue reading
Austin, Texas is one of the great party towns of the Southwestern United States. Ask anyone west of the Mississippi River where a good place to hear live music is, and they will tell you without hesitation, Austin, Texas. The city is well known for its live music scene that has introduced generations of TV viewers to it, and all of the genres that it encompasses, through the long running series, Austin City Limits. So it’s only logical that if people flock to Austin to see live bands, they will need a place to stay after the show. Cue the Austin Hilton.

Philips Lighting has revealed laboratory work on an LED-based replacement for fluorescent tubes in which a so called TLED (Tube lighting LED) tube delivered 200 lm/W, including the driver, at a 3000K warm-white CCT. The company said it will bring such a solid-state lighting (SSL) product to market in 18 months to two years.
Philips chose to announce the lab project because of the magnitude of the opportunity for energy savings. Jy Bhardwaj, senior vice president or research and development, said 50% of global commercial lighting uses fluorescent tubes. The best such fluorescent lights operate in the 100-lm/W range so efficiency in that application could double in two years.
In the US, fluorescent lights consume 200 terawatts annually according to Philips. The company said retrofit of all such lighting with 200-lm/W tubes would be the equivalent of 50 medium-sized power plants. Continue reading
