High Efficient Lighting

Lighting can account for up to 20% of a school's electricity consumption.  There are four categories of lighting typically used in schools:
  • fluorescent tubes, typically found in the classrooms; 
  • standard incandescent bulbs; 
  • exit signs bulbs, which are small, but used 24/7; 
  • larger lamps for the gymnasium and auditorium.
By replacing all these lights with newer ones using more efficient technology, it is possible to reduce their consumption by close to 35% without affecting the level of lighting in the rooms. In fact, the lighting levels may be increased even though the electricity consumption is lower.
