What’s affecting lighting

Recent legislation –

EPACT 2005; EISA 2007

New DOE Rulemaking –T12, PAR halogenThis year manufacturers are petitioning DOE to postpone ruling giving rare earth phosphor shortages

Energy Standards & Codes –ASHRAE 90.1; IECC

Universal Waste Rule –Mercury & Recycling

Rare earth phosphor shortage driving up costs for fluorescent lamps –

T12, T8, and CFLs

New Lighting Federal Regulations

2010, July –

magnetic ballast for T12s gone

Replacement options: Electro-magnetic ballast or electronic T8

2012, July –

Most T12 and least efficient T8 lamps will be no longer be available

2012, July -

Several standard PAR halogens can not be sold2012 to 2014, Jan 1st –

Why did you do the project?

Would you have done it without a rebate?

Maintain Current Rebates in 2013But focus on:

• LEDs• T8 Retrofits• Controls

Next steps for LIGHTENUP

GOAL: Increase LEDs in market for program cost effectiveness• Replaces non legislated incandescent or HIDs• Installed in long hour applications that have been

untouchable before with CFLs -

retail, outdoors• Promote adding dimming and controls for added savings• Future outlook shows LEDs will be cheaper and more

efficient and can replace HIDs, linear fluorescents, etc cost effectively

• Consider using Lighting Facts, ENERGY STAR, DLC and LDL lists for qualified LEDs

LEDs

• Continue T12 retrofit rebates and encouraging de- lamping with retrofit kits.

• Increase T8 retrofits and use of retrofit kits for both T8 and T12 de-lamping

• Untouched opportunity in buildings built over the past 15 years during the building boom

• Rebates are going to be the driver for T8 retrofits and they have a high NTG ratio

Linear Fluorescents

Increase use of controls –

wireless controls sensors, daylighting, task tuning, dimming systems

• New LED fixtures are going to be ready for these in future years

• Controls are not cost effective in all types of applications, but can be a good add on to a retrofit project for additional savings.

Controls

Education for contractors/customers • IESNA recommendations and design for light levels

In a space and retrofit options• LEDs and right applications• Controls and daylight harvesting• Contractor sales training• Other…

Contractor and Customer Education

Explore the idea of point of purchase rebates for LED bulbs with distributors (i.e. mid or upstream rebates).

Possible to apply to other technologies in future
