Sports Teams Use of LEDs Highlighted

NHL franchise the Montreal Canadiens and MLB team the Seattle Mariners are two professional sports teams experimenting with LED lighting as a means of cutting their energy bills and adding flexibility to their lighting, reports The New York Times.

Bell CentreThe Canadiens’ home, the Bell Center, last year installed 140 LED fixtures to light its playing surface. The LEDs produce three times as much light per watt that the high intensity discharge lamp they replaced and will save the venue $125,000 a year in electricity bills, the paper reports.

Part Three: Advanced Lighting Control Strategies Like Light Level Tuning, Demand Response Save Energy

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

Part Two: Daylight Harvesting, Other Dimming Strategies Help Lower Energy Costs

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

Part One: Advances In Lighting Technology Give Facility Managers New Options For Savings

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
