Example: Monitoring air quality at school
Concerned about the health of children and aware of the harmful effects of prolonged exposure to a too high CO2 level, the DGS of this medium-sized city decided to call on Agora Software to monitor the air quality in schools.
From our platform, he interconnects the CO2 sensors placed in the classrooms and an instant messenger of his choice (MS Teams in this case) with users (technical agents, teachers and school director).
When the CO2 level is too high, according to predefined conditions, an alert is sent to the teacher’s phone inviting him to open the window.
The teacher indicates that he/she has indeed carried out the recommended action by replying to the message received, otherwise another person can be informed to take over.
For her part, the principal can ask for the CO2 level of a class from her email by simply asking the question.
The DGS can consult the air quality history for each classroom and thus identify the relevant actions to be taken (installation of ventilation devices in particular rooms for example), or report on the good ventilation in its buildings.
Elements that must interact:
CO2 and VOC sensors
Installed in each room to be monitored (classrooms, canteen, multipurpose room…)
Calendar of use of the premises
To take into account the context of the data and determine who to notify if critical thresholds are exceeded
- Current and forecasted weather;
- Road and port traffic ;
- Pollen concentration;
- Outdoor air quality;
- Climatic alert (heat wave, extreme cold, storms)…
Persons concerned by the measures
In notification (alert on threshold crossing, daily bulletin…) and in real time interrogation:
- Technical Services Department;
- Technical manager of the school;
- Teachers and directors of the school…
To go further...
As a major public health issue, air quality must be strictly controlled and improved.
Schools, canteens, sports facilities, theaters and any closed room receiving the public and agents, all places where it is necessary to control the concentration of certain pollutants:
- Carbon dioxide (CO2): it is an index of confinement in public places. When the concentration approaches 1000 ppm (parts per million), it is time to ventilate (open the window, force the ventilation, etc.);
- Volatile Organic Compounds (VOCs): toxic above 1000 µg/m3, they are often produced by wall coverings, paints, furniture, etc. Here also, it is advisable to improve the ventilation of the premises.
Beyond the physical measurement of these values, it is necessary to draw conclusions in real time: warn the teacher to open the window, the technical director to put the room under surveillance, increase the flow of the ventilation system, etc.

Which plan for your city?
Indoor air quality (IAQ) monitoring is mandatory in nursery and elementary schools as well as in day care centers since January 1, 2018, and in leisure centers, colleges and high schools since January 1, 2020. In all enclosed spaces, air quality is a public health issue.
