Lifestyle trends have caused the quality of indoor air to be considered a crucial health factor especially since poor air quality in classrooms is proving to have negative effects on students’ health and academic performance. Tightly sealed and enclosed building as per new building regulations to make buildings more energy efficient do tend to have a build of carbon dioxide from many sources inclusive of humans. Let us take, for example, a classroom, where close to 40 persons or more may gather at a time, each releasing between 20 and 25 liters of carbon dioxide per hour through respiration alone; this usually winds up with poor air quality being the end result which can lead to the “sick building syndrome” phenomenon. The introduction of carbon dioxide sensors in classrooms has proven to help in alleviating this problem. This small, technologically advanced device measures the levels of carbon dioxide present in the room to help find solutions to improve and control ventilation rates. The use of carbon dioxide sensors in schools can prove beneficial and advantageous to students in classrooms.

First and foremost, the simple to use carbon dioxide sensors make it easier to monitor and improve air quality through effective ventilation procedures. Some carbon dioxide sensors require them to be installed simultaneously with the air conditioning systems while others can be manually maneuvered. Nonetheless, both types of carbon dioxide sensors work in similar contexts, providing readings in real time which aids in finding proper ventilation solutions. On the contrary, failure to improve indoor air quality may result in illnesses associated with symptoms such as headaches, fatigue, shortness of breath, sinus congestion, coughing, sneezing, eye, nose, throat and skin irritations, dizziness and even nausea

Secondly, research published by the University of Tulsa’s Indoor Air Program in 2010 stated that students who are in a thoroughly ventilated classroom score better on tests than their peers who are in a lesser ventilated environment. Furthermore, this said study showed that a well ventilated classroom has a lesser amount of pollution and contaminants which too results in healthier students who are more alert in class.

Richard Shaughnessy, program director of Indoor Air Quality Research at TU and a research associate in the Department of Chemical Engineering, stated that many schools do not provide healthy learning environs for its pupils. He further went on to say that, by improving ventilation levels, administrators and teachers can help students explore greater learning potentials.

To augment his arguments, further research also proved that indoor air pollutants can cause discomfort, increased absenteeism and reduced productivity. It also puts a strain on the relationships between teachers and students.

In the same breadth, the use of carbon dioxide sensors in schools also reduces energy costs associated with increased cooling and heating needs which sometimes waste energy. Its usage can cut energy costs by an estimated 60% and save the environment from the effects of wasted energy-which, in turn, make it safer for everyone.

In addition, having a well ventilated room will lower the amount of reported respiratory related illnesses in the state. A decline in illnesses of this nature will also reflect positively on the country’s economy as they will not need to overspend on healthcare.

In concluding the topic, the use of carbon dioxide sensors in classrooms has many advantages; the most important is the improved air quality monitoring. Such a boost in air health also has positive effects on the individual’s health, which aids them in living and enjoying a better quality of life.

    Intriguing topic, indeed, and one that should be considered and prioritised. To add, researchers at the Berkeley National Laboratory have shown that moderately high indoor concentrations of carbon dioxide (CO2) can significantly impair people’s decision-making performance.
