THE LUMINOUS ENVIRONMENT FOR SCHOOL CHILDREN.
THIS ARTICLE PRESENTS BASIC PRINCIPLES OF PROPER SCHOOL LIGHTING, DRAWING DIRECTLY FROM THE NEW "AMERICAN STANDARD GUIDE FOR SCHOOL LIGHTING." PRINCIPLES FOR PROVIDING A COMFORTABLE AND EFFICIENT VISUAL ENVIRONMENT ARE THESE--(1) ANY SCHOOL LIGHTING SYSTEM SHOULD BE DESIGNED IN SUCH A MANNER THAT IT WILL CONTRIBUTE TO A CHEERFUL, FRIENDLY, AND AESTHETICALLY PLEASING ENVIRONMENT, (2) UNDER OPTIMUM CONDITIONS FOR VISUAL COMFORT AND EFFICIENCY, THE BRIGHTNESS OF THE TASK SHOULD BE EQUAL TO OR SLIGHTLY GREATER THAN THE BRIGHTNESS OF THE ENTIRE VISUAL ENVIRONMENT, (3) IN A CLASSROOM THE BRIGHTNESS OF ANY SIGNIFICANT SURFACE VIEWED FROM ANY NORMAL STANDING OR SITTING POSITION SHOULD NOT DIFFER EXCESSIVELY FROM THE BRIGHTNESS OF THE VISUAL TASK, (4) THE BRIGHTNESS OF SURFACES IMMEDIATELY ADJACENT TO THE VISUAL TASK IS MORE CRITICAL IN TERMS OF VISUAL COMFORT AND EFFICIENCY THAN THAT OF MORE REMOTE SURFACES IN THE VISUAL SURROUNDINGS, (5) THE BRIGHTNESS DIFFERENCE BETWEEN ADJACENT SURFACES IN THE VISUAL SURROUNDINGS SHOULD BE REDUCED TO AN ACCEPTABLE MINIMUM, (6) THE CHARACTERISTICS OF ANY LIGHTING SYSTEM SHOULD BE SUCH THAT THE DIRECT AND REFLECTED GLARE ARE NOT OBJECTIONABLE, AND (7) DAYLIGHT AND ELECTRIC-LIGHT SYSTEMS SHOULD CONFORM TO SOME BRIGHTNESS AND BRIGHTNESS-DIFFERENCE PRINCIPLES, AND BOTH SYSTEMS SHOULD BE COORDINATED TO ASSURE THE EFFECTIVE CONTRIBUTION OF BOTH. TOPICS DISCUSSED INCLUDED--(1) SCHOOL LIGHTING'S CHANGING NEEDS, (2) VISUAL ENVIRONMENT, (3) VISUAL TASKS IN SCHOOLS, (4) LIGHTING QUALITY, (5) REFLECTANCE, (6) GLARE, DIRECT AND REFLECTED, (7) SYSTEMS OF ILLUMINATION, AND (8) HOW TO GET THE BEST RESULTS. THIS ARTICLE APPEARED IN THE MARCH, 1963 ISSUE OF THE AMERICAN SCHOOL BOARD JOURNAL. COPIES MAY BE OBTAINED BY WRITING THE EDITOR, BRUCE PUBLISHING CO., 400 NORTH BROADWAY, MILWAUKEE, WISCONSIN. (RK)
