  1. Lighting, Controls and Energy Savings How Architectural Engineers Impact Building Energy Use

  2. Visible Light

  3. Visible Light • Subtractive color mixing • Paint or Ink • Additive color mixing • LIGHT!

  4. Light Source Technology Did you know? Sunlight has all colors of the rainbow and appears WHITE

  5. Visible Light • Reflected light is what we “SEE” • The RED apple is red because it absorbs all light except RED • The GREEN apple is green because it absorbs all light except GREEN
