Presentation Transcript

  1. Energy Basics What is the “Best” lighting

  2. “Sic Semper Tyrannis”

  3. What is the “BEST” Lighting? The right light levels, at the right location, for the lowest cost

  4. I have to save $ in my building, NOW WHAT? • Lighting Technologies • Fluorescent • High Intensity Discharge • Solid State (LED) • Lighting Controls • Lighting Design • Lighting Maintenance

  5. Comparative Analysis

  6. Greatest Thing since Thomas Edison? YES? NO? MAYBE?

  7. The “BEST” measures for a lighting system? • Approximately 50% of the equation for light levels is the lumens/watt. • Approximately 50% is the environment those lumens sit in. • What are the some other factors? • Cost • Lamp life • CRI/K temp • Heat

  8. “BEST” Lighting • T8!! • Lowest cost • Great energy savings • Flexibility • High burn hours • Legacy • Yes, they still have mercury. • Very low depreciation

  9. LED? • Still dealing with high cost • Efficacy is improving almost weekly, lm/watt continue to rise. • Physics say it could get to 260 lm/watt, then we have REAL energy savings. • Creates a legacy problem • Great for dimming. • Relatively low environmental impact. • Still dealing with BAD manufacturers and marketers.

  10. LED Marketing

  11. Effective Controls Turn the D#$& LIGHTS OFF! Simple occ/vacancy sensors Use Daylight, IT’S FREE! Dimming, comfort and personal preferences raise costs, evaluate carefully! Can’t manage what you don’t measure, but measuring and not managing is STUPID!

  12. TRAINING • Recent EE program test took place for K-12 in GA. • Program took and existing training package, Building Operator’s Certification and applied it to K-12. • First reported results, 6 months • 72% posted data • Savings, $124,000+(spend was $30,800) • Training PAYS for itself!
