Embodiment Construction

[0009] [specific implementation plan]

[0010] In classrooms where both north and south walls are illuminated, the area of ​​daylighting windows on the north side should be larger than that on the south side, and the total glass-to-ground ratio of a classroom should be between 1:2.5 and 1:3.5;

[0011] The glass-to-ground ratio with only the south wall as the daylighting surface is 1:4;

[0012] Only the glass-to-ground ratio of the north wall for lighting is 1:1.5 to 1:3, and the light-transmitting area of ​​the north wall of the classroom is greater than the light-proof area.

[0013] Indoors with daylighting windows in the south should be equipped with sunshade devices to avoid excessive glare into the eyes;

[0014] In newly built, rebuilt and expanded classrooms, the natural lighting area should be enlarged as much as possible within the range of glass-to-ground ratio of 1:1.5 to 1:4 without affecting the load bearing of the teaching building and avoiding beams and colum...

Abstract

The present invention provides a method of improving natural lighting of classroom and belongs to the field of natural lighting technology. Lower glass window-to-ground area ratio of classroom results in poor lighting of classroom and high myopia rate of pupils and students. The present invention has the technological scheme of raising the glass window-to-ground area ratio of classroom to 1 to 1.5-4 to improve natural lighting of classroom.

Description

[technical field] [0001] The invention relates to the field of indoor natural lighting, especially the natural lighting of school classrooms. [technical background] [0002] The national standard GB 7793-87 on classroom lighting in primary and secondary schools sets that the glass-to-ground ratio of classrooms should not be lower than 1:6, and the minimum value of lighting coefficient on classroom desks should not be lower than 1.5%. But the facts prove that the current lighting effect of the classrooms is poor, especially the illumination of the classrooms away from the windows is insufficient in the classrooms where the lighting is mainly from the north, and the glass-to-ground ratio of the classrooms is not greater than 1:4. [0003] Over the past 20 years, a large number of Chinese students have suffered from myopia. The study found that the first factor is the light, the second is the distance of sight, and the third is the negative effect of glasses. Although the res...
