Lighting Sources for School Uses

Lighting Sources for School

Lighting is and always has been an important factor in designing and operating schools. Until the 1950s, natural light predominated as a means of illuminating most school spaces. Classroom design was based in large part on time-honored relationships between window sizes and room dimensions.

As electric power costs declined and designers began to take advantage of the increased flexibility provided by electric lighting, daylighting took a secondary role. Now, highly energy efficient windows and skylights and a renewed recognition of the positive psychological and physiological effects of daylighting (Heschong Mahone Group) allow a healthy and economical mix of natural and electric illumination in new and renovated schools.
