Code Of Lighting School Buildings PDF Download

Excerpt from Code of Lighting School Buildings There are 20,000,000 school children in the United States who are devoting several hours each day to study or to the performance of other work equally trying to the eyes. According to the available statistics nearly 10 percent, of the number of school children examined are found to have defective vision. The severe requirements imposed upon children's eyes by modern educational methods create need for the best of working conditions. Among these conditions lighting is of first importance. Improper lighting causes eye-strain, resulting in functional disorders, near-sightedness and other defects of the eyes. The following Code of Lighting School Buildings has been prepared by committees of the Illuminating Engineering Society in order to make available authoritative information for legislative bodies, school boards and others who are interested in enactments, rules and regulations for better lighting. The requirements of the code as set forth in the Articles, are based upon good practice at the present time. Standards of illumination and other requirements are subject to revision by the Society with advances in the art of lighting. While the code is intended primarily as an aid in formulating legislation relating to the lighting of school buildings, it is also intended for school authorities as a guide in individual efforts to improve lighting conditions. Acknowledgment is made of the valuable co-operation of many members and non-members of the Society in the preparation of this code.
