CO2 Dashboards for Ventilation Monitoring in Schools

In February 2020, the CO2 in this particular classroom was reaching peaks of 6,000ppm and for a large portion of the time, the CO2 is greater than 1,500ppm. In October 2020, due to the COVID-19 pandemic, the schools were requested to keep all windows open with the result that the CO2 remained below 1,000ppm on any given day. This presented clear evidence of the impact of ventilation on CO2 in ...

Tips for Reducing CO2 Emissions Trapped in Your Home

For schools, reducing the number of children in each classroom, or even holding class outside, will help keep the CO2 levels lower. If this can’t be avoided, opening some windows, checking the condition of the ventilation system, or at least keeping the classroom door open will help as well. For offices, having shorter meetings or holding meetings in a larger space can prevent this from ...

Healthy Buildings – Schools For Health

For improving indoor air quality in the classroom, we recommend prioritizing control strategies — ventilation, filtration, supplemental air cleaning — and targeting a combined 4-6 air changes per hour (ACH) for classrooms through any combination of these approaches. Other spaces in schools such as gyms, auditoriums, kitchens, and nurses’ offices may require different targets for the ...
