| Abstract | Natural lighting was the primary light source in buildings prior to the invention of the electrical lighting in 1879. After that, artificial lighting was mainly utilized to supplement natural lighting. Artificial lighting has nowadays become the major source to illuminate working spaces. However, due to the growing concern of passive design, energy efficiency and environmental issues, daylighting is integrated with artificial lighting to reduce energy consumption. The benefits obtained from the efficient utilization of daylight are not limited to architecture and energy aspects only. Rather, natural lighting affects building occupants in various aspects. This includes occupants' preferences, health, performance, and productivity. This paper aims to review the previous literature to highlight the impact of daylighting on building occupants, particularly in schools and office buildings. Many studies have proven that a large number of students and office workers (60-85%) prefer daylighting as a source of illumination. It was found that proper daylighting designs help maintain good health, reduce stress levels of office workers and alleviate headaches. Internal lighting conditions have had a noticeable effect on building occupants' performance and productivity. An increase of about (5-15%) in the productivity of office workers was reported when daylight was efficiently integrated with artificial lighting in their working places. The reviewed studies showed an increase in students and teachers' attendance in classes, which were mainly illuminated by daylight. In addition, students' progress was faster in math and reading tests (20-26%) compared with those, who occupied a classroom with less daylighting. |
