Comparing Jan 2008 vs 2009 provides big savings because of the occupancy difference. Jan2008-Mai2009= 25,000 KwH is more realistic

10. > 10 ELECTRICITY CONSUMPTION (2008 – 2009) Start replacement Roof Signage lamp with LED String (January 2008) Start replacement all Halogen Lamp with Halogen LED 7w (December 2008) Start replacement all TL lamp with LED String Lamp (January 2009) What’s happened here ? You should show the Occupancy as well for a better analysis

11. > 11 THE STRENGTH & THE WEAKNESS A.Strength : 1.Life time longer 45. 000 Hrs 2.Easy installation 3.Lumen ( 150 lumen ) 4.Save 80 – 90 % energy B. Weakness : 1.Expensive 2.For replacement should be replace fitting also ( Halogen type ) 3.For streaming type make new installation for replacement fluorescent Type lamp What means “Streaming” ? Please explain

12. > 12 GREEN GLOBE PROGRAM 1.Saving energy 2.Reduce quantity waste for lamps 3.Not using gas like Neon, Mercury etc at list friendly with environment

13. > 13 GREEN GLOBE PROGRAM FOLLOWING OUR Chief Engineer Meeting and the Presentation of the work we are doing with PHILIPS, each time you want to change lighting, you should ask yourself : Am I going to change the Design ? Take a picture Before and After What is the lighting ambiance I should keep ? LUX and LUMEN per sqm or else (contact Philips for help to mesure) If I use FLC or Halogene or other Lamp producing “Dangerous Gas” : How I will handle the used Bulbs after (Recycle ? Give to a specialized company ?) Try to set up a Grid of Return of Investment with the help of the Supplier (philips) is recommended of course) Take into consideration the REAL TIME the light is SWITCHED ON (24 HOURS is only for some specific public areas) OUR COMMENTS
