Abstract: Kindergartens are important community facilities that introduce children to a classroom learning environment. The research aimed to examine current practices in kindergarten heating, cooling, and ventilation and investigate how IAQ and thermal comfort interact with each other at five selected kindergartens in Melbourne. This research used field measurements to investigate indoor air quality (IAQ) and thermal conditions during the COVID-19 pandemic and used CO 2 concentration levels as an indicator of IAQ. The research found that high CO 2 levels above recommended maximums were reached in operational kindergartens. The highest level identified during class time was 1908 ppm. Conditions outside recommended levels for thermal comfort were also recorded. A kindergarten operating with the use of both mechanical and natural ventilation was found to have lower CO 2 levels than the kindergartens relying solely on mechanical ventilation. However, thermal comfort was compromised in this kindergarten. The data collected in kindergartens in their natural settings offered insights into the actual ventilation conditions in these facilities and provided baseline data for developing pandemic-resilient kindergartens. The findings are relevant to kindergartens in other countries that have dynamic window/door-opening behavior.
