Ensuring good air quality in classrooms is essential for student health and academic performance. Poor ventilation can lead to various health issues and hinder learning. Effective air conditioning and ventilation systems play a role in fostering healthier, more productive learning environments in schools.
Improving School Air Quality for Better Learning
Studies across Victorian primary and secondary schools have revealed that CO₂ levels often exceed acceptable standards, with some classrooms reaching as high as 5,000 ppm during school hours. The National Construction Code (NCC) recommends CO₂ levels remain below 850 ppm on average over an 8 hour period. When these levels are exceeded, students may experience headaches, fatigue, and difficulty concentrating, all of which impact their ability to learn.
Elevated CO₂ levels are especially problematic in the winter months when ventilation is harder to maintain. During this period, when illnesses like colds and flu spread more easily, good ventilation reduces the risk of airborne disease transmission.
Ventilation and Cognitive Performance
Poor air quality doesn’t just affect health, it also impacts cognitive performance. Children’s developing respiratory systems make them particularly vulnerable to the effects of elevated CO₂ levels. Prolonged exposure can increase absenteeism and reduce focus in class. Studies show that improving air quality leads to better attention, reduced fatigue, and greater overall engagement in lessons, which supports improved academic performance.
Maximising the flow of fresh air is the most effective way to ensure good indoor air quality. Schools can achieve this by opening windows and doors where possible or using mechanical systems like air conditioning and fans. Even during extreme weather conditions, strategies like ventilating for 10 minutes every hour can make a significant difference.
To balance ventilation with safety, many schools install fly screens or mesh security doors. These allow fresh air circulation while maintaining security within classrooms. In spaces where outdoor ventilation is limited, regular air changes through mechanical systems are vital for maintaining a comfortable learning environment.
Purifying Classroom Environments
Air purifiers play a valuable role in maintaining clean indoor air, especially in classrooms where ventilation options are limited. While they don’t replace fresh air from open windows or mechanical systems, they can help filter out dust, allergens, and airborne particles including viruses and bacteria.
Modern HVAC systems can also be equipped with built-in air purification features, allowing schools to improve air quality as part of their regular climate control. For best results, purifiers should be chosen based on room size and regularly maintained to ensure they continue operating effectively.
Improving School Environments with Climate Control
As schools continue to focus on the health and well being of students, investing in climate control systems is key. Whether through improved ventilation, air purifiers, or regular maintenance, the goal is to create environments that help students thrive both academically and physically.
