Lighting is a big part of the savings
LIGHTENUP Rebate Summary 2012 Fixture type 4 ft T12 /magnetic ballast $./Watt With New Bonus for Retrofit Kits +$0.10/Watt 4 lamp $0.35 $0.45 3 lamp $0.40 $0.50 1, 2 lamp $0.45 $0.55 8 ft T12 linear fluorescents $0.50 $0.60 T8 Retrofits $0.55 $0.65 HID to Induction Replacements $0.40 LED replacement lamps and LED fixtures $0.30 to $0.50 GU24 based CFLs with conversion kit $0.10 400W HID to High Bay Fluorescents $0.40 Automatic Controls and other $0.50
What s affecting lighting Recent legislation EPACT 2005; EISA 2007 New DOE Rulemaking T12, PAR halogen This 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 sold 2012 to 2014, Jan 1st phase in ~30% more efficient incandescent A-lamp bulb 100W (2012), 75W (2013), 60W (2014) A19 bulbs, some flood lamps
What s the new baseline? New T12 baseline Shows that there is still over 2/3 (67%) Savings beyond Fed Leg

Why did you do the project?
Would you have done it without a rebate?
Next steps for LIGHTENUP Maintain Current Rebates in 2013 But focus on: LEDs T8 Retrofits Controls Education New program model pilot?
LEDs 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
Linear Fluorescents Continue T12 retrofit rebates and encouraging delamping 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
Controls 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.
Contractor and Customer Education 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
New program model? 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
