Presentation Transcript

  1. E4ME–TV presents… • Energy Quest #13 • Awesome Appliances and Innovative Illumination • February 5th @ 7:00 p.m. EST

  2. February 5, 2013 Energy for ME Energy Quest webinar

  3. The output of the light source is the lumen output • The wattage is the input (how much power that source uses). Lighting Facts is a great tool to compare light sources

  4. Look for the efficacy of the light source to maximize efficiency. Lumens per watt can be compared to miles per gallon.

  5. Lumens per watt (like miles per gallon) Remember this?

  6. The future of LEDs and beyond… • Theoretically, the lumen per watt maximum is over 200 lumens per watt. • Currently, LED products are getting close to 100 lumens per watt. • We are not even half way to the finish Blue LEDs are coated with yellow phosphor to make white light More phosphor may improve color rendering, but reduce light output

  7. What is the color of that vase?

  8. Color rendering- Be careful with that comparison Phosphor research and improvements are now yielding LED products with CRIs over 90

  9. Other considerations with light sources

  10. We are getting better at dimming LED sources • Edison base sockets come from Thomas Edison- dies in 1931 • We are using old foundations to build new products • New products will change CCT using amber chip to mimic incandescent • Dim from your I-Pad, I-Phone, (Soon to be released) • LEDs can be turned on and off with little damage to the LED. Fluorescent does not tolerate cycling well. • LED drivers are now commonly 0-10v dimmable, which will make new LED fixtures more controllable. • You could have sensors that control when the fixtures are on, how bright they are, turn off immediately when someone leaves the room • You could have exactly the right amount of light. No waste.

  11. Strategies • Daylight Harvesting • Occupancy Control • Personal Control • Task Tuning • Time Scheduling • Variable Load Shedding

  12. Someday, maybe we’ll feel safer because the lights are NOT on • Sensors will become even more prevalent • Integrated with computers and LEDs- addressable

  13. Conclusion • LEDs are getting to be more efficient • Phosphors in LEDs are yielding better color and better color rendering • LED lighting is becoming very controllable • Occupancy sensing, dimming, scheduling, load shedding • There will be even more controls. • Questions?

  14. Efficiency MaineResidential Programs 1/31/2013

  15. Efficiency Maine Introduction • Manages Maine’s energy efficiency and renewable energy programs. • Established by the Maine Legislature in 2002 with mandate to reduce energy costs, help the environment, and promote sustainable economic development • Funded by: • electric rate payers • large fossil fuel power plant pollution “allowances” • ISO-NE power grid for “negawatts” • Federal grants

  16. Energy Efficiency is Cheaper Than Generation

  17. Lighting and Appliances = 25% Source: http://www.energystar.gov/ accessed 1/2013

  18. ENERGY STAR Appliance Rebate Program $25 $50 $100 $50-100

  19. Residential Lighting Program • Reduced CFL and LED prices in stores • Some stores have Instant In-store Rebates • CFL’s are often cheaper than incandescents • LED’s are as low as $10/60W equivalent • They pay for themselves in as little as 8 days • Prices range from 22c to $7/CFL – look for our logo

  20. Electricity Monitor Loaner • Borrow from any library • Monitor any 110V device • Simple to use • Find “phantom loads” • Justify a new fridge or TV 
