One might assume that, within the walls of a school, it is the shared responsibility of the school nurse, guidance counselor, physical fitness instructor, and food services staff to protect student health. In truth, such an important responsibility also belongs, in very large part, to the educational facility planner and school maintenance staff. Both help control which products and materials will be used to construct and furnish the school building. If carefully selected, these products and materials can have an extremely positive impact on a school's indoor air quality. And good indoor air quality can, in turn, have positive impacts on student and teacher health--including increased concentration and productivity, improved test scores, and decreased absenteeism due to fewer asthma and related illnesses. By making more informed decisions about the products used to construct and furnish a school building, educational facility planners can help ensure optimal indoor air quality--and, in turn, a healthier learning environment.
