This is a prototype of a tool that can be used to define the maximal level of ventilation (ach) based on the concentration of a pollutant in outdoor air of a specific location. The default values are for particulate matter.

Maximal ventilation level (ach) to ensure safe level of outdoor pollutant indoors

Maximal allowed concentration from outdoors to indoors(ug/m3):

Decay rate of the pollutant (h-1):

Penetration factor (fraction of outdoor concentration entering indoors):

Concentration of the pollutant outdoors (ug/m3):
