How does your campus protect students from air pollution?

Vanessa O'Brien

Senior Sustainability Officer at Lincolnshire City Council

It has been great to be able to work with such a large number of students and share live local air quality data with them. All the schools have seen the benefit in understanding what the data is telling them, and how this can be used to inform decisions about how and when to travel.

We work mainly with the local authorities for deploying the Node-S devices — with the local council. The community has been really helpful and has made a big difference. The majority of the Nodes are up on street lamps around the town.

"Having real-time, very hyper-local data about the air quality where you are spending your time has great potential to impact people, in terms of the decisions they make, but also in terms of making that connection between the environment and health."

Julie Orth

Class Teacher, Sierra Waldorf Elementary School

"Having the sensor on site is great for our school and a nice service to offer our surrounding community. Our device went in about 3 years ago and is working great! It is so important for us to know our air quality. Whenever it hits unhealthy levels, we keep our students inside. The data is available right on my phone, so I can check it ahead of recess and make a real-time decision on whether to send students outside or keep them on an indoor activity schedule when air quality is over the threshold. "

Superintendent/Principal, Pope Valley USD

“We chose Clarity because they provided up-to-date, local, scientifically-backed, and relevant data to make decisions about whether to keep students inside. Because of the geography and demographics in our county, the official air monitoring stations are about an hour away with hills in between, providing irrelevant data. We would have poor air quality and the official stations would be cleared; or the official stations would show heavy particulate levels and we would have clean air."

Air quality guidelines for schools — know when to switch to indoor activities

Reduce absences and protect student health

Studies have found that a single day of unhealthy air quality can more than double absences. Absences come at a cost to both schools, and students' families.

Improve academic performance

Exposure to outdoor air pollution can inhibit cognitive development and negatively impact academic achievement. Studies have found air pollution levels to be a statistically significant predictors of student performance.

Make better decisions with real-time air data

Air quality can change rapidly, making it important to have access to real-time air quality data when making operational decisions. Monitoring air quality ensures you make the right decisions for student health.
