• Some available evidence indicates that teacher health, in regard to voice impairment, may be adversely affected by noisier environments, although the magnitude of the effect cannot currently be estimated as a function of exposure to noise.

Recommendation 4: To facilitate student learning, guidelines for green schools should include requirements to meet American National Standards Institute (ANSI) Standard S12.60, “Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools.”


Finding 6: In regard to building condition and student achievement, the committee has found the following:

  • The body of available research is suggestive of an association between the condition of a school building and student achievement. All of the studies analyzed by the committee found that student test scores improved as the physical condition of school buildings improved. The degree of improvement of students’ test scores varied across the studies, but in all cases students in buildings in better condition scored higher than students in buildings in poor condition.

Recommendation 5: Guidelines for green schools should place significant emphasis on operations and maintenance practices if potential health and productivity benefits are to be achieved and maintained over the lifetime of a building.
