SOLATUBE CASE STUDY
DOUGLAS COUNTY SCHOOL DISTRICT
Over a period of six years, Colorado’s Douglas County School District saved $16.5 million through energy auditing. One of its most successful strategies was daylighting, which reduced electricity use for lighting and cooling equipment. It also benefitted the district’s sustainability efforts. By retrofitting older schools with Solatube® Daylighting Systems, consistent, high quality natural light was delivered to building interiors without reconfiguring the plenum space or making major structural modifications.
“The Solatube Daylighting Systems have proven not only to be more effective than artificial light, as far as being brighter and more resilient, but it also gives the sense of being connected to the outside. Morale and performance have historically improved with that. In fact, they not only improve the learning environment and morale of the students and staff, they also save significant funds as far as our utility budget, and that money goes back into the classroom.”
