This interim report informs the eventual user of the direction of the long-term program; specific criteria are not provided. Five current guidelines in lighting practice were disavowed as follows--(1) that low levels of illumination cause organic harm to the eyes, (2) that the footcandle is the best criterion for determining the proper…

The role of reflected glare and visual viewing angles in near task performance is discussed, and following statements are reported--(1) a worker at a desk normally assumes a position in which his eyes traverse an area of work extending from a point approximately vertically below his eyes to a point not more than 40 degrees from the vertical, (2) a…

The same form of lighting will not be effective in all areas of a school facility. Factors to be considered include physical and psychological effects, visual requirements, and cost. A chart illustrates type of lamp, output/energy ratio, light "quality," and applications. (MLF)

In this speech, the author traces the history of lighting in schools, discusses the variables affecting the amount of illuminance needed, and provides a table of illuminances recommended for Ontario schools. Other factors that affect vision--glare, veiling reflection, color, and brightness balance--are outlined. Planners are admonished to…

Research gathered by the Functional Efficiency Division of the National Building Research Institute, South Africa, is aimed at providing lighting conditions under which the school child can produce his maximum effort with the least strain and fatigue. These favorable conditions are outlined along with specific examples of their realization in…

Poor lighting conditions in classrooms result not only from low intensity light but also from too high intensity light, an uneven distribution of light, and glare. Since visual tasks in a classroom constitute 62 percent of a student's time in school, suggestions are made of ways lighting conditions can be improved. The principles and…

From a series of lectures, a selection of eight are oriented principally toward the biologically developing child, and the physiological operations in visual process. The numbered lectures are--(1) The Coordinated Classroom, its Philosophy and Principles, (2) An Outline of a Biological Point of View, (3) The Evolution of Structure--despite man's…
