In the 155 simulation of the scenario before lockdown, the microenvironments were run with no particular 156 recommendations; thus, people enter the microenvironments and queue indoors, often resulting in 157 overcrowded environments.

    Document: were simulated for each microenvironment: before lockdown (B) and after lockdown (A). In the 155 simulation of the scenario before lockdown, the microenvironments were run with no particular 156 recommendations; thus, people enter the microenvironments and queue indoors, often resulting in 157 overcrowded environments. Since most of the indoor microenvironments in Italy are not equipped 158 with mechanical ventilation systems, the simulations were performed considering two different 159 situations: natural ventilation (a typical value for an Italian building equal to 0.2 h -1 was adopted, both natural ventilation and mechanical ventilation; in this case a slight increase in the air exchange 167 rate (AER) for natural ventilation (0.5 h -1 ) was considered in order to take into account that the door 168
