Modern principles of color applied to schools will greatly improve the scholastic performance of students. (Author/MLF)

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)

Reviews and evaluates studies of the effects of light, color, and air quality on the learning environment. Concludes that studies suggest a role for light in establishing and maintaining physiological functions and balances and a need for improved air quality in airtight, energy efficient buildings.
