Abstract

The last pandemic that hit all the countries in 2020 has inevitably led scientists and researchers to investigate and examine the indoor air quality in all types of enclosed spaces as people tend to spend most of their time inside the buildings. The students' group is one of the largest groups of people who spend most of their time in classrooms, characterized by a high occupant intensity and often by insufficient air quality. Therefore, the educational building is an important indoor environment for measuring air quality. This paper aims to investigate the factors that affect infection risk transmission and the strategies that can mitigate the transmissibility of the infection. The methodology involves two distinct elements: indoor environment quality factors and engineering control strategies. The results show that the factorsaffecting indoor air quality are relative humidity, temperature,CO2 and ventilation. Also, the control strategies that can mitigate the infectious risk and improve indoor air quality are ventilation, air filters and ultraviolet radiation.
