Daylighting Systems for Education Applications

Studies have shown that natural light improves students' test scores, while promoting better health and physical development.


Daylighting is linked to a significant rise in student test scores and learning rates. An extensive study of 21,000 students in three different school districts found that students with the highest quality daylighting in their classrooms "progressed 20% faster on math tests and 26% faster on reading tests in one year when compared to students in the least daylit classrooms."

The findings of a two-year long study conducted at four schools in Alberta, Canada show how daylighting effects the healthy development and academic performance of elementary school students:

  • the students in full-spectrum light were healthier and attended school 3.2 to 3.8 days more per year;
  • libraries with superior light resulted in significantly lower noise levels;
  • full-spectrum lighting induced more positive moods in students; and
  • because of the additional vitamin D received by the students in full-spectrum light, they had 9 times less dental decay and grew in height an average of 2.1 cm more (over the two year period) than students attending schools with average light.

According to the U.S. Department of Education, school energy costs average $176 per student per year. Proper daylighting and lighting controls can save up to $85 per student per year.

Ciralight SunTrackers provide consistent, high-quality natural light all day long. They are used in elementary and high schools in the districts of Davis, Los Angeles, and Riverside as well as in the higher education facilites of the California Institute of Technology.
