1 ENERGY-EFFICIENT LIGHTING OPTIONS Andy Vaughn, Energy Program Engineer SAIC, an Ameren Illinois ActOnEnergy Partner OUTLINE Best practices in lighting equipment and application Lighting cash incentives available through ActOnEnergy The ActOnEnergy Online Store How to get started on your energy-efficient lighting project 1

2 What are the benefits of energy-efficient lighting? Lighting Usage in the Commercial Sector LIGHTING TECHNOLOGIES AND INCENTIVES 2

3 COMPACT FLUORESCENT LIGHT BULBS (CFLs) CFLs use 1/4 to 1/3 less electricity than incandescent bulbs Online Store provides CFLs at approx. half the cost Technical points: High temperature rated Dimmable Light quality COLOR TEMPERATURE CFL with soft light (~2700K) CFL with cool light (~4100K) Converting from T12 to High Performance T8 or T5 Linear fluorescent lighting - 53% of the commercial lighting electrical use - 66% of the industrial lighting electrical use (Buildings Energy Data Book from the Department of Energy) 3

4 CONVERTING FROM T12 TO HIGH PERFORMANCE T8 If you: Then you: Replace 1 magnetic ballast and 4 T12 lamps with 1 electronic ballast and 4 high performance T8 lamps Use 33% less electricity Save $12 per fixture Receive $12 to $20 in incentive DO YOU HAVE T12 LIGHTING? Look at the end of the fluorescent tube T12s have a diameter of 1 1/2 inch T8s have a diameter of 1 inch T5s have a diameter of 5/8 inch LIGHTING T12 PHASE-OUT ActOnEnergy s next T12 bonus ramp-down will go into effect June 1, This ramp-down will permanently reduce the current 10% cash incentive bonus on lighting projects that replace T12 lamps or fixtures. Ballast T8 lamp 4

5 HIGH BAY FIXTURES Before After OCCUPANCY SENSORS Great when used with fluorescent fixtures with programmed-start ballasts and LEDs Optional delays of 30 seconds to 30 minutes 20% to 40% energy savings Save up to $10 to $20 per sensor per year LED LIGHTING Use 75% less energy than incandescent Last 35 to 50 times longer than incandescent bulbs and 2 to 5 times longer than fluorescent Reduced cooling costs Ideal for power cycling Marks of High Quality Test Standards: LM-79 and LM-80 ENERGY STAR DesignLights Consortium (DLC) DOE award products 5

6 LED EXIT SIGNS Electrical cost of older exit signs is typically $30-$65/year LED exit signs electrical cost is ~$3/year EXTERIOR LIGHTING High-powered LEDs now available LIGHTING DESIGN Meet target light levels Maximize source efficacy Maximize fixture efficiency Automatically control lighting Optimize for changing tasks and space 6

7 FLUORESCENT REDESIGN Retrofit option Average footcandles Power per fixture (W) Energy savings (%) Annual operating cost ($) Base case: Energy-saving T12 lamps with magnetic ballasts Case 1: T8 lamps with electronic ballasts Case 2: Highperformance T8s with electronic ballasts Case 3: Case 2 + new fixture* + 50% less lamps Case 4: Case 3 + occupancy sensing and day lighting dimming N/A Upgrade cost ($) N/A 1,165 1,320 2,035 2,625 Simple payback without incentive (years) Simple payback with incentive (years) N/A N/A N/A CASE STUDIES Case Study: Fast Food Restaurant What equipment was installed One 2-lamp 4 HP T8 and Twentyfour 4-lamp 4 HP T8, and three LED exit signs Energy savings in kwhs 11,602 kwhs Energy savings in dollars $1, Project cost $2, Incentive received $ % of project covered by 28.6% incentive Payback with incentive 1.03 years 7
