Actions to Improve
IAQ in Schools
In recent years, schools have begun to recognize that
various environmental factors can infl uence the academic
performance and overall health of their students. Accurate
monitoring of air quality, carbon dioxide (CO2), humidity,
and temperature are critical for providing students
with a suitable learning environment. Abnormally high
levels of CO2 can signifi cantly impact concentration,
decision-making, and test scores. Sensors that measure
CO2, temperature, and relative humidity have become
commonplace in many preschools, primary and secondary
schools, vocational training centers, and adult education
facilities. The Government of Quebec is leading the way
as the fi rst province in Canada to deploy measures that
aim to ensure proper air quality in all classrooms within its
school network. Quebec schools are expected to monitor
their ventilation systems, identify problematic classrooms,
and take corrective action when needed.
Proper indoor air quality and ventilation help reduce
the aerosol transmission of diseases. Because indoor
CO2 is mostly produced by the occupants of a space,
a concentration below 1500 parts per million (ppm)
indicates good ventilation, with the ideal target set by the
Ministry being below 1000 ppm.
Belimo room sensors have been installed worldwide,
standing out for their precision, stability, and dualchannel
technology. They deliver accurate readings free
of measurement drift, eliminating the need for calibration.
Built-in Near Field Communication technology allows
for quick and easy access to data, on-site control,
commissioning, and troubleshooting using a smartphone
and the Belimo Assistant App.
Simplicity, accuracy, reliability, and connectivity make
commissioning and maintaining Belimo room sensors a
quick and easy process.
