“…It is directly linked to the room characteristics, the number of persons present, outdoor air quality, and ventilation rate. The CO2 concentration of 1000 ppm is often stated as a typical threshold level for good IAQ [8]. If it gets higher than this can cause poisoning and have been shown to affect the human thinking process.…”

The COVID-19 crisis has affected the process of how the study procedures are organized at schools in Latvia. Three different options were available for the school to choose from. However, most schools have opted for option A which states that the classes are organized face-to-face but various safety measures must be ensured. Each class or group is equated to a closed set where there are no distance requirements. In turn, the distance between the classes must be observed. This means that students stay in the same class all day and are accompanied by teachers of the respective classes. This can lead to improper ventilation as for most of the schools in Latvia it is organized through the opening of windows. To test this, measurements of CO2 concentration were done in a classroom Secondary School in Daugavpils. The results showed that the CO2 concentration was very high and often reached and exceeded the maximum measuring capacity of the device - 4000 ppm. It indicates that following the special safety procedures cause a negative effect on IAQ as the classrooms are not properly ventilated. This can lead to a drop in the performance of pupils as well as stimulate the transmission of other infectious diseases. Further measurements are necessary to gather data from different schools and best practices must be found.

This paper was presented to determine the volume unit of indoor based on the human carbon footprint. The purpose of this approach was to formulate the ideal dimensions of an indoor, which was able to maintain human health. The basis for determining the dimensions was adapted to tropical conditions. For users in non-tropical areas, slight adjustments to temperature and ventilation may be required.Some examples of indoor dimension evaluation and planning were presented in this paper. In general, it was obtained that the indoor dimension could be found using the volume unit of a healthy room of3.0 m 3 /person/hour. The volume unit was linear with the number of users and time of existence in the room. This contributed significantly to people, who can easily and quickly find out the dimensions of space according to their needs.

“…Values over 5000 ppm lead to discomfort and rapid heart rate, over 15 000 to problems with breathing and over 30 000 to dizziness and indisposition. Concentrations above 60 000 may cause a blackout [23]. The highest permissible concentration in the work environment is 9000 mg/m 3 i.e.…”

Maintaining the proper indoor microclimate and the correct level of thermal comfort is extremely important due to the impact of the surrounding environment on people's satisfaction, well-being, health, and work. This problem is particularly important in rooms where children spend long periods as the environment has a stronger influence on their still-developing organisms. The study assessed the microclimate parameters, the state of human thermal comfort, and the level of carbon dioxide concentration, as well as the maintained levels of comfort and air quality after the application of improvements aimed at rationalizing heat consumption in educational buildings. The results of basic thermal and personal microclimate parameter measurements, as well as carbon dioxide levels, were presented. The assessment of human thermal comfort was based on measured values, the Predicted Mean Vote, and Predicted Percentage Dissatisfied. The average rating of thermal comfort in the observed environment was within the acceptable comfort zone, but high concentrations of carbon dioxide indicates low efficiency of the ventilation system.
