Some of the qualities and quantities that must be juggled to produce good lighting for educational facilities are analyzed with photographs, tables, and drawings. The three categories of lamps used for school lighting (incandescent, fluorescent, and high intensity discharge) are described; a lamp selection guide gives the design characteristics of lamps in each category. The effectiveness of windows, the advantages and disadvantages of windowless schools, and screening devices for controlling glare and sunlight are discussed along with aspects of daylighting design for new schools. Scientific findings applicable to light in schools are summarized. Considerations met by the provision of manual switching, time, photoelectric, and other light controls are described. Guidelines are offered for appraising an existing lighting system. Related improvement procedures are categorized as those that require no capital investment, those with a short pay-back period, and those with a long pay-back period. Exterior lighting and forecasts of lighting in the year 2000 conclude the booklist. A glossary is provided and the appendices contain drawings and descriptions of the principal lamp types used, as well as two statements from official sources concerning the effects of ultraviolet radiation.
