  6. 6. light light state dark state
  7. 7. 7
  8. 8. 8
  9. 9. sunlight electricity light state dark state
  10. 10. • variable transmission windows reduce penetration of light cleared activated
  11. 11. architectural buildings consume 68% of all electricity in the US 30% of building’s energy is lost through inneficient windows automotive solar heat through glazing increases AC use decreases fuel economy up to 30% reduces the battery range of Electric Vehicles
