Indoor air quality (IAQ) in classrooms

We have deployed sensors in our buildings to measure CO2 levels, temperature, and humidity in your classrooms in real time. This data allows you to monitor the containment index of each space to ensure a healthy learning environment.

Why improve air quality?

On average, we spend 85% of our time in enclosed environments. 

Maintaining living spaces in compliance with current standards reduces the transmission of infectious diseases.

The reduction of pollutants brought in from outside must also be taken into account.

The lockdown index

Six indicators characterize the lockdown, ranging from a very favorable situation to an extreme lockdown requiring urgent action:
  • 0: zero lockdown
  • 1: weak confinement
  • 2: Medium lockdown
  • 3: High confinement
  • 4: very high confinement
  • 5: extreme lockdown

The study

A fleet of sensors is deployed in the various buildings and classrooms of the Université Grenoble Alpes. They allow for the measurement of 3 indoor air quality (IAQ) indicators:
  • CO2 levels.
  • Temperature. 
  • Humidity level.
Measurements are taken automatically every 10 minutes.

This data allows the calculation of the containment index, which will be calculated and displayed in the tested rooms. For rooms equipped with sensors, each user can view the data in real time.
