CO2 stands for carbon dioxide, which is a colorless and odorless gas.

It is a carbon compound that is formed during combustion, including the combustion that takes place in the body, which is also called our metabolism.

CO2 plays a significant role in the earth's climate system, as it can contribute to the greenhouse effect and thus affect the temperature on earth.

While CO2 is a natural part of the atmosphere, elevated levels of CO2 in enclosed spaces, such as schools and offices, can adversely affect the indoor climate and have a detrimental effect on the health and well-being of those occupying the space.

Reducing CO2 in the indoor climate can have several advantages, including:

• Improved health: Elevated levels of CO2 can lead to headaches, fatigue, eye and breathing irritation, and even reduced cognitive function. Reducing CO2 can therefore improve health and thereby increase the well-being and productivity of those staying in the room.
  
  
• Increased performance: Reducing CO2 can improve performance on tasks that require concentration and attention, which are important for both students and employees in workplaces. This can increase efficiency and performance in the workplace.
  
  
• Improved indoor air quality: By reducing CO2, you can reduce the risk of indoor air pollution that can arise from other sources such as paint, household chemicals and cleaning products. This can also result in reduction of allergies, asthma and other respiratory problems.

If you want to measure the CO2 level in your indoor climate, there are several methods you can use. Pay particular attention to:

1. That the sensor measures CO2. Many cheap sensors only measure humidity and temperature or have an "environmental sensor". You can easily be tricked into thinking that you have bought a CO2 sensor, even though you have actually just bought a thermometer.
2. That the sensor is documented. If you have found a CO2 meter, be sure that it has been tested by an impartial third party. A great many sensors on the market are imprecise and downright useless for indicating the CO2 level.
   

One of the most effective methods is to use a CO2 meter, such as THE CLOUD from OPEN. SKYEN is a simple and reliable device that measures the CO2 level and gives you precise measurements.

The market for indoor climate meters has exploded, so it is important that you find a reliable supplier of your CO2 meter. The sensor in SKYEN from ÅBN is a genuine CO2 sensor which has been thoroughly tested by the Norwegian Technological Institute.

Here are some simple methods to reduce CO2 levels indoors:

1. Open windows: Allow for fresh air by opening windows and doors. Create drafts if possible. It will help to ventilate the room and reduce CO2 levels.
2. Use CO2 sensors: CO2 sensors monitor the level of CO2 in the room and will alert you when the levels get too high. With SKYEN you can see when the CO2 level is too high - SKYEN will light up red.
3. Regular HVAC System Maintenance : Have your heating, ventilation and air conditioning (HVAC) system checked regularly to ensure it is running optimally and that CO2 levels remain low.

If the CO2 level in a room exceeds 1,000 ppm (parts per million), it can lead to a number of symptoms such as headaches, fatigue, reduced cognitive function, increased blood pressure and irritation of the eyes and respiratory system.

If the level reaches 5,000 ppm, it can lead to more serious symptoms such as dizziness, nausea and even fainting. Therefore, it is important to monitor and reduce CO2 levels in indoor spaces to ensure healthy indoor air quality.

In 2018, the World Green Building Council published a report showing that a healthier working environment can reduce sickness absence by 58% - equivalent to four days per year. employee per year.

A team of English researchers has documented that optimal ventilation provides a reduction in the relative risk of COVID-19 infection by more than 70%. Therefore, many countries, including our own, have recognized ventilation as a special weapon in the fight against viruses.

Sick Building Syndrome (SBS) is a condition that describes a range of symptoms such as headaches, dizziness, fatigue and breathing problems that can be experienced when staying in a particular building. Symptoms appear to be related to the length of time one has been in the building and tend to disappear after leaving the building.

SBS can be caused by various factors such as poor indoor air quality, inadequate ventilation, high levels of CO2 and other pollutants, increased humidity and poor lighting. In addition, the presence of allergens such as dust, mold and bacteria can cause irritation of the respiratory tract and trigger asthma or allergic reactions.

No. Traits by themselves usually do not cause disease. Infectious diseases spread between people, so if you are isolated, such as on the Greenland ice sheet, you would not catch a cold or the flu, as there is no one to infect you.

Nevertheless, drafts can increase the risk of diseases developing. When a person is exposed to cooling, drafts or cold air, the blood in the body is drawn away from the skin and mucous membranes to protect the internal organs. This can lead to a reduction in the effectiveness of the immune system in the mucous membranes.

However, it must be emphasized that drafts do not usually cause serious illnesses unless they lead to a permanent or prolonged cooling.
