Clean Air Schools for U
Poor indoor air quality (IAQ) in schools can significantly affect the health, concentration, and performance of students and staff. Clean Air Schools for U aims to improve IAQ and reduce greenhouse gas emissions through energy efficiency assessments, pollutant monitoring, and the evaluation of reduction strategies. By deploying sensors and providing tailored management plans, the project creates healthier, more sustainable learning environments.
Improving School Indoor Air Quality
Indoor air quality (IAQ) in schools is a critical concern, as pollutant levels can be 2-5 times higher than outdoors, impacting the health, concentration, and performance of students and staff. Clean Air Schools for U aims to improve IAQ and reduce greenhouse gas emissions through energy efficiency assessments, pollutant monitoring, and the evaluation of mitigation strategies.
Sensor Deployment
Air quality sensors are being deployed at approximately 30 schools to provide real-time monitoring of carbon monoxide, carbon dioxide, particulate matter, tVOCs, and radon. This data allows schools to make informed adjustments, such as improving ventilation or replacing HVAC filters, to create healthier environments.
Energy Assessments
Comprehensive energy assessments of school buildings are performed to identify opportunities to reduce energy consumption and lower operational costs. Practical recommendations are provided for each school, including the optimization of HVAC settings during air pollution events.
Sensitivity Analyses
Using air quality measurements and HVAC system data, the project identifies key ventilation and filtration parameters that impact indoor pollutant levels. Multivariate regression, machine learning models (Artificial Neural Networks), and CONTAM simulation software are used to provide guidance for school building managers on improving IAQ and energy efficiency.
Phone App Development
Two interactive phone apps are being developed to help school personnel identify and mitigate IAQ pollutant sources. One app utilizes engaging 3D graphics to showcase common pollutant sources, while another allows users to scan real classroom environments to automatically identify potential air quality issues.
Community Engagement & Impact
Beyond assessments and monitoring, Clean Air Schools for U invests directly in participating schools and communities — through advisory boards, free equipment, and rigorous evaluation of what's working.
Community Engagement
Communities are actively involved through Community Advisory Boards (CABs) , which guide project interventions, educational materials, and app development. Additionally, questionnaires are distributed to school staff and parents to gather insights on IAQ concerns and health impacts to help shape project strategies.
Distribution of Free Air Filters and Cleaners
To immediately reduce exposure to indoor air pollutants, the project distributes free high-efficiency air filters and portable air cleaners to participating schools.
Impact Assessment
The impact of IAQ interventions is assessed by comparing pollutant levels and daily school absenteeism rates before and after implementation. The project also uses follow-up surveys to track changes in complaints and conducts energy assessments to estimate emissions reductions and cost savings.
