  77. 77. A Word About Commercial Lighting Lighting is the #1 or #2 Largest User of Electricity in Most Buildings in America Houston Skyline
  78. 78. Commercial Lighting 44% of the Electricity in Health Care Facilities is Lighting
  79. 79. Incandescent Bulbs Still Widely Used 60+ Coal- fired plants domestically 250+ Coal- fired plants worldwide Halogen spots and MR16s continue to be popular

  81. 81. Fluorescent Tubes Good Better BEST A word about fluorescent tubes: NARROWER IS BETTER Never use magnetic ballasts. Electronic ballasts are quieter, more efficient, and eliminate flicker.
  82. 82. Good Better BEST Electronic vs. Magnetic Ballasts (for tubes) Electronic ballasts are more efficient than magnetic ballasts … resulting in an overall lamp- ballast system efficacy increase of 15% to 20%. Other advantages of the electronic ballast include reduced weight, quieter operation, and reduced lamp flicker. Electronic ballasts are directly interchangeable with magnetic ballasts. (From LBNL website) You should always use electronic ballasts, especially with motion detectors.
  83. 83. 84% of a Building’s Carbon Footprint Comes from its Utility Bill
