Ventilation in educational institutions: how to improve concentration and health of students

Carbon dioxide in classroom air can significantly affect students’ well-being and ability to concentrate. Insufficient ventilation leads to a buildup of carbon dioxide, which often causes fatigue, drowsiness, and lower productivity. That’s why it’s important to regularly refresh the air to ensure comfortable learning conditions and maintain high indoor air quality.

When ventilation in educational spaces is insufficient, levels of harmful substances—particularly carbon dioxide—rise. This negatively affects the health of students and teachers, leading to frequent headaches and poorer concentration. Modern systems from the Ventilator® online ventilation store make it possible to effectively control air quality and prevent such problems.

Carbon-dioxide buildup in classrooms is a common issue due to inadequate ventilation. To improve air quality, it’s necessary to implement ventilation systems that provide a stable supply of fresh air. This not only increases student comfort but also positively impacts attention and overall health.

Stuffy classrooms in educational institutions: the problem

The company Prana draws attention to the importance of quality ventilation in educational institutions, since classroom air directly affects students’ well-being and productivity. In modern schools and universities, elevated concentrations of carbon dioxide (CO₂) are often observed, which can exceed the recommended level of 1,000 ppm. This leads to drowsiness, reduced attention, headaches, and an overall drop in learning effectiveness.

The main cause of such problems is insufficient air exchange in classrooms. Because of limited room volume and large numbers of students, the air quickly becomes saturated with carbon dioxide, harmful substances, dust, and volatile organic compounds. All of this negatively affects the body—particularly the respiratory tract—and reduces students’ concentration and productivity.

How to improve classroom air quality

Install modern ventilation systems that efficiently supply fresh air and remove exhaust air, with heat recovery.
Ensure regular air-quality monitoring using CO₂ sensors to track concentrations of carbon dioxide and other harmful substances.
Organize optimal air exchange so the amount of fresh air per person meets sanitary requirements.
Use recuperators to maintain building energy efficiency and reduce heating costs.
Schedule regular breaks to air out rooms, especially where effective mechanical ventilation is absent.

How ventilation affects well-being and learning

A properly designed ventilation system in educational institutions maintains an optimal microclimate, controls humidity levels, and reduces concentrations of harmful bacteria and dust.
Better classroom air quality improves concentration and increases student productivity.
Effective ventilation reduces the risk of headaches, drowsiness, and respiratory illnesses.
Providing sufficient fresh air helps maintain a comfortable oxygen level, which is essential for healthy development and learning.
A ventilation system with heat recovery reduces energy costs and makes schools more energy-efficient.

Air-quality improvements can be achieved with low-noise ventilation systems. These systems ensure continuous fresh-air supply, effective exhaust removal, and stable temperature and humidity—without excessive acoustic load. This makes classrooms more comfortable, boosts student productivity, and allows them to focus without distracting noise.

How CO₂ affects learning: the importance of quality ventilation in schools and universities

In educational institutions—such as schools and universities, especially primary and secondary levels—indoor air quality is critical for the health and productivity of pupils and students. A high level of carbon dioxide (CO₂) in the air negatively affects our ability to concentrate, leading to drowsiness, headaches, and reduced learning efficiency.

The main reason for CO₂ buildup is insufficient air exchange in classrooms where many people gather. As a result, indoor air quality declines and oxygen levels drop, directly affecting the well-being of students and teachers. That’s why it’s necessary to install modern ventilation systems with air-quality control and fresh-air supply, which deliver outside air and remove exhaust air with a high CO₂ content.

The role of ventilation and sensors in controlling CO₂ levels

Ventilation units with heat recuperators maintain optimal humidity and temperature, creating a comfortable learning environment.
Monitoring with dedicated CO₂ sensors makes it possible to control carbon-dioxide levels in classrooms and promptly adjust air exchange.
Natural ventilation combined with mechanical systems helps effectively remove volatile organic compounds and other pollutants that accumulate indoors.

The impact of CO₂ on productivity and health

Elevated CO₂ levels in educational settings lead to reduced productivity and attention among schoolchildren and students.
Where ventilation systems don’t meet requirements—or are absent—the air quickly becomes saturated with CO₂, causing discomfort and worsening the overall microclimate.
Properly organized ventilation in schools and universities helps improve classroom air quality and supports better well-being and health for students.

Therefore, school ventilation is a key factor influencing the air in educational spaces and ensuring a comfortable, productive learning environment. Installing modern ventilation systems and regularly monitoring air quality will improve air exchange, reduce CO₂ concentration, and create a healthy microclimate in classrooms.

Sanitary requirements for air exchange in educational institutions

Air quality in schools, universities, and primary and secondary institutions directly affects the health and productivity of students and teachers. Ensuring proper air exchange is fundamental for creating a comfortable and safe environment, with air sufficiently oxygenated and free from harmful substances—particularly carbon dioxide (CO₂) and volatile organic compounds.

Sanitary ventilation requirements in educational facilities call for a steady supply of fresh air and efficient removal of exhaust air. This prevents CO₂ buildup—which causes drowsiness, headaches, and reduced concentration. That’s why it’s important to use modern ventilation systems equipped with sensors to control air quality and automatically regulate air exchange.

Ventilation systems and heat recuperators

Units with heat recuperators not only supply fresh air but also retain heat, increasing the efficiency and energy savings of the ventilation system.
Ensuring proper air delivery to classrooms is key to improving air quality and student well-being.
Natural ventilation remains important, but to maintain a productive and safe atmosphere it should be complemented by mechanical equipment.

The importance of sanitary norms for educational institutions

Compliance with ventilation requirements helps avoid the accumulation of harmful substances and maintains optimal oxygen levels.
Balanced air exchange supports a comfortable microclimate, improves well-being, and reduces the risk of respiratory diseases.
Regular air-quality checks using modern devices keep the ventilation system in working order and enable rapid response to any changes.

Thus, adhering to sanitary standards and implementing an effective ventilation system are the best ways to ensure comfort and health in educational institutions, where we spend much of our time and where air quality affects our well-being and productivity.

Types of ventilation: simple solutions, recuperators, automation

Proper ventilation is the key to ensuring quality air—oxygen-rich and free of excess carbon dioxide—which directly affects our well-being and productivity, especially in primary and secondary schools as well as universities.

There are several basic types of ventilation systems, each with its advantages and suited to different conditions:

Natural ventilation — the simplest way to bring in fresh air by opening windows and ventilation valves. It helps remove exhaust air but doesn’t always provide stable air exchange, especially in large or densely furnished rooms.
Mechanical ventilation with a PR-series recuperator for round ducts — a modern solution that not only supplies fresh air but also recovers heat from the exhaust air, greatly improving energy efficiency. Recuperators are an ideal way to improve classroom air quality, reduce heating costs, and ensure a comfortable microclimate year-round.
Automated ventilation systems equipped with sensors to monitor CO₂ levels, humidity, and other parameters. Such systems automatically regulate supply and exhaust based on real needs, helping avoid poor air quality, reduced concentration, and drowsiness.

A ventilation system is one of the most important ways to improve the air we breathe, particularly in spaces where many people gather—classrooms, university lecture halls, and offices.

When choosing a ventilation type, consider the building’s features and user needs. Simple solutions suit small rooms, while recuperators and automation deliver a higher level of comfort and health, maintaining ideal air quality in your environment.

KVZ equipment for schools and kindergartens

Providing quality ventilation in educational institutions is a key task for creating a comfortable and safe environment for children. In schools and kindergartens, it’s especially important to control carbon-dioxide levels indoors, since elevated CO₂ causes reduced concentration, drowsiness, and even headaches in children.

For effective air control in classrooms and playrooms, modern sensors are installed to monitor CO₂ levels, humidity, and other parameters. This allows timely responses to declines in air quality and activation of ventilation systems, preventing discomfort and reduced performance.

KVZ equipment (ventilation control and protection) includes a wide range of devices—from simple fans to complex systems with recuperators. Recuperators not only deliver fresh air but also retain heat, making system operation more economical and eco-friendly. They significantly improve the indoor microclimate, especially when natural ventilation cannot cope with the load.

In universities and schools, KVZ equipment helps maintain optimal learning conditions, as air quality affects well-being and the ability to concentrate. In kindergartens this is even more relevant, because children’s health requires special attention.

Investing in modern ventilation systems is a way to improve children’s well-being and provide a healthy environment for development. Thanks to quality ventilation and KVZ equipment, schools and kindergartens can guarantee high classroom air quality—a foundation for successful learning and children’s health.
