Productivity Enhancements Due to Natural Light

An exhaustive study of 21,000 students in three different parts of the country has shown incredible benefits in learning where natural light is provided to the classrooms. Students learned about 20% faster in rooms with daylighting than in rooms with electrical lighting. This study was performed by the Heschong Mahone Group (HMG) for Pacific Gas and Electric Company (PG&E). Full details of the study can be obtained from HMG, using the link below.
