Indoor Air Quality–The Impact from the Way of Use in terms of Ventilation One method to strengthen IAQ is airing the rooms and is effective when the outside air is clean (low PM concentration). At particular times, not during winter, it really is inexpensive and simple to operate. However, if outside air pollution is high, this action may well temporarily worsen indoor air excellent. Consequently, to confirm the above thesis, the carbon dioxide concentration change and PM10 levels in playrooms of selected nurseries in various measurement periods were analyzed. For B1, using the worst air good quality, and B4, using the very best indoor air quality, the course of CO2 and PM2.5 concentrations on winter days with all the finest (07 December 2020) andEnergies 2021, 14,One particular approach to strengthen IAQ is airing the rooms and is successful when the outdoors air is clean (low PM concentration). At certain occasions, not throughout winter, it’s cheap and straightforward to operate. Nonetheless, if outside air pollution is higher, this action may well temporarily worsen indoor air high-quality. Thus, to confirm the above thesis, the carbon dioxide concentra tion change and PM10 levels in playrooms of selected nurseries in distinct measurement 12 of 27 periods have been analyzed. For B1, together with the worst air high-quality, and B4, using the best indoor air good quality, the course of CO2 and PM2.five concentrations on winter days with all the finest (07 December 2020) and the worst (14 December 2020) outdoor air high-quality had been analyzed. The outcomes are shown the worst (14 December 2020) outside air top quality had been analyzed. The results are shown in Figure 4a,b for nurseries B1 and B4, respectively. in Figure 4a,b for nurseries B1 and B4, respectively.
