Exterior Lighting

By upgrading to energy efficient lighting, you save money. Another important savings factor for exterior lighting (or any difficult to reach area) is the savings achieved through reduction in maintenance costs.

Energy efficient exterior lighting takes two approaches: using the most efficient types of lamps, and using efficient controls to determine when the lighting is used.

LED Lighting and Controls Save London School EUR 25,000 Annually

The Business Academy Bexley, a public school in London, has been upgraded with 8point3 LED lighting and Lutron adaptive wireless controls. The school reduced its lighting energy costs by 60%, which resulted in an annual savings of EUR 25,000 ($34,860). A seven-year financing scheme allowed zero upfront cost for the project.

DENVER – Denver International Airport (DIA) is retrofitting more than 5,400 lights located in the airport’s east and west parking garages with energy-efficient LED fixtures.

The majority of the lights are being replaced with 51-watt LEDs. Combined with other lighting systems in the project, DIA expects a net energy savings of about 45 percent, resulting in energy cost savings of about $327,000 per year. Continue reading

Lighting Up The Lawn With 16 Million Colors

It starts with an innocent string of incandescent holiday lights around a porch window, maybe a plastic caroler or two on the front lawn.

Then it escalates: Twinkling lights are in the shrubs, Santa’s on the roof, an inflatable Frosty the Snowman is on the lawn and next to him is one of those little white wire reindeer with a head that turns ever so slowly.

Nice work, holiday decorator. But do you have lights that can be controlled by tracing your finger over the face of a smartphone? Do you have 16 million colors available at the flick of a switch?

Lumenplay’s LED lights can create any color, controlled by a mobile app.

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 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

Is This The End of T12 Lamps and Ballasts?

What’s Happening?

  • Manufacturers are phasing out production of T12 lamps and ballasts.
  • Less availability of T12 lamps and ballasts.
  • Increased costs, up to triple the normal price, because of supply and demand of T12 lamps and ballasts.
  • To meet energy efficient federal regulations, manufacturers will focus on T8 and T5 lamp and ballast production.
  • There’s a limited opportunity to access incentive funds from utility companies for T12 lighting upgrades. Continue reading
