Examine facility attributes that most affect academic outcomes and in what manner and degree. The research is examined in six categories: indoor air quality, ventilation, and thermal comfort; lighting; acoustics; building age and quality; school size; and class size. Spatial configurations, noise, heat, cold, light, and air quality obviously bear on students' and teachers' ability to perform. Clean air, good light, and a quiet, comfortable, and safe learning environment are needed. This can and generally has been achieved within the limits of existing knowledge, technology, and materials. It simply requires adequate funding and competent design, construction, and maintenance.
