Children are not the same as adults. Schools are not the same as office buildings.

Because we value schools as special places with precious occupants, CHPS supports an evidence-based approach to the design, construction, and operation of school facilities. We support in partnership or spirit any effort that seeks to better understand and explain the connection between the physical environment and the well-being of students, teachers, and school administrators. The Knowledge Library is a clearinghouse of studies, reports, and other resources that will help you learn about this important connection.

Towards Healthy Schools, Healthy Schools Network

http://www.healthyschools.org/data/files/TowardsHealthySchools-Risks.pdf

All states require children to attend school, but no state ensures that those schools are environmentally safe and healthy. “Towards Healthy Schools: Reducing Risks to Children” is the fourth in a series of triennial state of the states’ reports from Healthy Schools Network and its partners in the Coalition for Healthier Schools, dating from 2006. This report features published media reports on environmental conditions from every state in the country. This disturbing summary highlights stories across the country teachers, parents, and guardians, and the children themselves, face numerous and serious unexamined and unaddressed risks to health and learning, rarely acknowledged by public agencies.

Healthy Schools STAR Research grants improve the understanding of the relationship between environmental factors in K-12 educational facilities and the safety, health and academic performance of children, and the effectiveness of teachers and staff. Key components of each grant are research, community engagement and community capacity building. Five grantees from 2015 completed studies and reports available through the site.

An assessment of indoor environmental quality in schools and its association with health and performance. Building and Environment. (2015) 1-6.
https://www.sciencedirect.com/science/article/pii/S0360132315001092?via%3Dihub - link to abstract

A school district composed of 70 schools in the Southwestern United States engaged in research over two academic years to examine the associations between different indoor environmental quality (IEQ) indicators and student performance. Researchers collected data on absenteeism and health as a baseline   Classroom ventilation rate, temperature, and hygiene of high contact surfaces appear to be important (IEQ ) parameters, and potentially related to student health and/or performance.

Study on Elementary Student Performance Relative to Surrounding "Greenness" of the School

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4195655/ - link goes to the abstract

This study investigated the association between “greenness” of the area surrounding a Massachusetts public elementary school and the academic achievement of the school’s student body, based on standardized tests with an ecological setting. Results indicated a consistently positive significant association between the greenness of the school and school-wide performance on both English and Math tests, even after adjustment for socio-economic factors and urban residency.

Association of Classroom Ventilation with Reduced Illness Absence: A Prospective Study in California Elementary Schools Indoor Air. Lawrence Berkeley National Laboratory: Lawrence Berkeley National Laboratory. LBNL (2013) Paper LBNL-6259E. Retrieved from: https://escholarship.org/uc/item/5633c9d1

Study investigated relationships between inadequate classroom ventilation rates (VRs) with increased illness absence (IA) in 162 third through fifth grade classrooms over a two-year period.  Classrooms were located in three school districts in varying parts of the state: South Coast of Southern California, San Francisco Bay Area and the Central Valley. Evidence suggests that increasing VRs would decrease absenteeism due to illness; thereby significantly increasing attendance-linked school funding with minimal increased costs.

This research studied the efforts of indoor air quality on most schools in one school district in Texas. Each school completed air quality renovations prior to the beginning of the research study. Although the study involved several complex factors, the evidence indicated that improving air quality in a classroom was more cost effective to improve student outcomes than decreasing class size.

Indoor Environmental Quality of Classrooms and Student Outcomes: A Path Analysis Approach. SeonMi Choi, PhD. Researcher, Interior Design, College of Design. University of Minnesota. Journal of Learning Spaces, Vol. 2, No 2 (2013).

The purpose of the study was to investigate the relationship between indoor environmental quality (IEQ) in a set of university classrooms and students’ outcomes. The researcher collected data from more than 600 students. Study criteria included thermal conditions, indoor air quality, acoustic conditions, lighting conditions, furnishings, aesthetics, technology, and view conditions. Evidence suggested positive student outcomes when specific design factors are included in university classrooms. Results of the study provided suggestions for additional research.
