In order to improve the teaching effect, protect the eyesight of students, improve the lighting and lighting conditions in the classroom, and enable the healthy growth of children and teenagers, this standard is specially formulated. This standard applies to the new, rebuilt and expanded general primary and secondary schools, secondary normal schools and kindergarten normal schools in cities, counties and towns.

The direction of the school classrooms should be determined according to the geography and begging conditions of each area. The east-west direction should not be adopted, and the north-south double-sided daylighting should be adopted. The classroom adopts single-sided daylighting. The light should enter from the left side of the student seat. When the north classroom is on the south outer corridor, the north-facing window should be the main lighting surface. 1.2 Classroom objectives
1.3 The lowest value of daylighting coefficient on the surface is not
1.4 It should be less than 1.5%, and the glass floor area ratio of the classroom should not be less than 1.5.
1.6 at 1:6. Classroom objectives in foggy areas (such as Chongqing, etc.) 1.7 The daylighting coefficient value on the surface is not 1.8 should be less than 2%
1.9 To prevent direct glare of the window
1.10 Curtains should be set up in the classroom to prevent direct sunlight from entering the classroom. To prevent the reflected glare of the blackboard
1.11 The surface should be made of wear-resistant matt materials. 1.12 To improve the lighting effect of the classroom
