This study was conducted to measure the illumination intensity of various rooms and to compare this result with "The guide line of the standard design for school buildings and facilities" formulated by the Ministry of Education. The illumination intensity of 41 rooms of 25 schools, reading quarters, night study rooms, reading rooms, libraries and practice rooms of vocational schools, was measured by a photoelectric photometer.
1. The average illumination intensity were 73 lux in reading quarters, 83 lux in night study rooms, 92 lux in libraries, 94 lux in reading rooms, and 210 lux in practice rooms of vocational schools. The ratio of the illumination intensity to the standard were 40-59% in reading quarters, and 60-79% in reading rooms, libraries, and practice rooms of vacational schools.
2. Among 41 rooms surveyed, only 3 rooms (7%) met the minimum requirement for illumination while the rest 38 rooms (93%) were not adequate.
3. The reason of inadequate illumination were the maintenance failures and energy saving policy as only 218 lamps in 899 lamps (24%) were lighted.
It is suggested that the proper illumination should be provided by furnishing necessary installations and turning on the lights to protect th eyesight of students.
