If you work or study at a school in England or Wales, you can get involved in CHILI.
What schools get
Schools in England and Wales are eligible to get two or more free air quality monitors, for indoors and outdoors. CHILI uses AirGradient monitors which measure carbon dioxide (CO2), particulate matter (PM), volatile organic compounds (TVOCs), temperature and relative humidity. Indoor monitors can be moved from room to room. Outdoor monitors will be fixed in place on the outside of your school building.
Once the monitors are connected, teachers and pupils can access their monitor data through an interactive Web App, co-designed by and for schools. You can see how air quality changes over the course of hours, days or weeks and months, and compare indoor and outdoor air.
The benefits for pupils and teachers
CHILI gives pupils the opportunity to contribute to scientific research and do their own hands-on experiments with their monitors. Through the Web App, teachers can support pupils to understand and investigate their air quality. You could use CHILI to help pupils learn about air quality and health, design experiments, improve their data skills, gain agency in controlling their environment, develop advocacy and responsibility… and much more!
Many of the activities in the Web App support curricular teaching and/or extracurricular accreditation schemes. The data may be useful for developing or supporting your school climate action plan (which each school’s sustainability lead is charged with developing)
Additional opportunities are available to schools participating in CHILI, including:

You can learn more about what taking part would involve, and sign up, through the SAMHE website, using the button below. SAMHE and HAPPEN are partnering to help deliver CHILI. HAPPEN is building on its long history of measuring children’s health and wellbeing in Wales. SAMHE is using its wealth of experience of air quality work in schools to monitor how energy efficiency adaptations change the indoor environment.
