Air quality in schools and common myths
Do you imagine that improving the air quality in a school classroom is simply a matter of opening a window? Unfortunately, the reality is much more complex. There are many myths about indoor air quality that can harm students' learning and health.
A common misconception is that air quality is only affected by visible pollution. In fact, research shows that invisible factors such as CO2 levels are crucial. The Danish Teachers' Association highlights that poor air quality can directly lead to symptoms such as headaches and difficulty concentrating , which underlines the importance of proper ventilation.
Another popular myth is that modern school buildings automatically have good air quality. The reality is that many schools struggle with inadequate ventilation. Health authorities recommend that CO2 levels not exceed 1000 ppm to ensure satisfactory air quality , while many classrooms far exceed this limit.
The myths about indoor air quality are numerous and harmful. They lead school leaders and municipalities to underestimate the extent of the problem. The truth is that air quality directly affects children's learning ability, concentration and general health.
Pro tip : Continuous measurement and documentation of air quality is the key to revealing and remedying hidden problems in schools' indoor climate.
Important air parameters and their significance
Air quality in schools is much more than just clean air. It is about complex parameters that directly affect students' health and learning potential. Various air components play a crucial role in the classroom environment.
Carbon dioxide (CO2) is a key indicator of air quality. The FOA's report highlights that CO2 concentrations above 0.1% (1000 ppm) in classrooms can lead to reduced concentration and fatigue among students . High CO2 levels signal inadequate ventilation and can have serious consequences for children's learning ability.
In addition to CO2, humidity , temperature and particle pollution are critical parameters. Too high or too low humidity can create uncomfortable environments. Temperature fluctuations affect student comfort, while microparticles and airborne allergens can trigger health problems.
The different air parameters are interconnected. A poorly ventilated classroom situation can accelerate the accumulation of harmful substances, worsening the overall indoor climate. Modern technologies enable precise monitoring of these parameters and allow schools to act proactively.
Here is an overview of key air parameters and their typical effect on the indoor climate:
| Parameters | Normal range | Possible consequences of deviation |
|---|---|---|
| CO2 level | Below 1000 ppm | Fatigue, decreased concentration, headache |
| Humidity | 30-50% | Irritation of mucous membranes, risk of mold |
| Temperature | 20-22°C | Discomfort, low comfort, increased illness |
| Particulate pollution | Low (varies) | Allergies, asthma, worsening indoor climate |
Pro tip : Implement ongoing air quality measurements and create a shopping list based on the collected data to ensure a healthy learning environment.
Rules and recommendations for Danish schools
Danish schools are subject to clear and stringent guidelines for indoor climate, which aim to ensure a healthy and optimal learning environment. These rules are not just recommendations, but concrete standards that must be adhered to in order to protect the health of students and staff.
The Danish Working Environment Authority's Executive Order on Indoor Climate sets clear limits for CO2 levels in classrooms. The main rule is that the CO2 concentration should not exceed 1000 ppm (0.1%), which corresponds to an acceptable air quality level. If the level exceeds 2000 ppm (0.2%), the ventilation is considered inadequate and requires immediate action.
In addition to CO2 levels, the recommendations also include other important parameters such as temperature, humidity and ventilation rate. Schools are recommended to have a temperature system that maintains between 20-22 degrees Celsius and a relative humidity of 30-50%. These ranges are designed to create optimal conditions for learning and prevent health problems.
It is not just a recommendation, but a legal obligation for schools to ensure a healthy indoor climate. Municipalities and school managements have a direct responsibility to continuously monitor and improve air quality through regular measurements, maintenance of ventilation systems and implementation of improvement measures.
Pro tip : Conduct quarterly air quality measurements and create an action plan that can quickly implement improvements if standards are not met.
Consequences of bad air for students
Poor air quality in schools is much more than an environmental problem. It is a direct threat to children's learning, health and general well-being. The consequences reach deep into students' daily lives and can have long-term effects on their educational and personal development.
According to reports from Dagens Byggeri, many schools have CO2 concentrations that are two to four times higher than recommended levels . This extreme level of air pollution can result in significant declines in students' learning ability and performance capacity. Research shows that improved ventilation can potentially increase students' academic performance by as much as 5-10%.
The health consequences are also serious. FOA's studies document that poor air quality can cause a number of bothersome symptoms in students, including eye irritation, headaches and significant concentration difficulties. These health problems not only affect the immediate learning situation, but can also have long-term consequences for children's mental and physical well-being.
The psychological aspects are often overlooked. A poor indoor climate can create stress, exhaustion and demotivation among students, further worsening their academic and social engagement. It is not just about air quality, but about creating a healing and supportive learning environment that promotes children's potential.
Pro tip : Continuous measurement and visible documentation of air quality can create awareness and action among school leaders and municipal authorities.
Effective solutions and measurement methods
A healthy indoor climate requires a systematic and intelligent approach to air quality measurement and improvement. Modern technologies now offer advanced solutions that can transform school environments from unhealthy to optimal learning spaces.
DTU's research-based recommendations highlight the importance of continuous CO2 monitoring and state that air quality should be maintained below 900 ppm with the possibility of frequent ventilation . CO2 sensors form the core of these modern monitoring systems, enabling real-time monitoring and rapid intervention when air quality deteriorates.
However, technological innovations go beyond just measurement. New disinfection solutions like Decon-X DX1 can effectively address complex indoor climate challenges such as mold and moisture issues , creating a healthier environment for students and staff.
The most effective solutions combine intelligent sensor technology with strategic ventilation control. This includes automatic ventilation systems that adjust air exchange based on real air quality measurements, as well as designs that enable natural ventilation through windows and intelligent ventilation ducts.
Below is a comparison of traditional and modern solutions for improving school air quality:
| Solution type | Example | Benefits | Disadvantages |
|---|---|---|---|
| Manual venting | Open windows | Fast and no investment | Uneven effect, cold |
| Mechanical ventilation | Ventilation system | Constant control, stable | Requires maintenance, expensive |
| Sensor control | CO2 sensors | Real-time tracking, precise | Requires technical integration |
| Air purification | Decon-X DX1 | Removes mold and bacteria | Requires periodic operation |
Pro tip : Implement a multi-layered measurement and improvement system that combines technical solutions with ongoing human attention and action.
