The description that reflects the majority of occupants in the space. This parameter is used to determine the breathing rate of the occupants that, in turn, affects risk in the space. The more an infected person breaths, the more opportunity for emission of infectious particles. Similarly, more inhalation results in more exposure to airborne pathogen.
Generally speaking, babies breathing rate is the lowest, followed by children, seniors, teens, then adults. Consideration should be given to this selection for mixed populations, where some combination of babies, children, teens, adults, and seniors may be present. For more conservative results, ParticleOne recommends selecting the occupants with the highest breathing rate. Users may also create multiple version of the occupant profile in order to test and measure sensitivity. Example: a K-6 classroom might be modelled as adults (teacher and TA), or fully as children such that the two sets of results can be compared and contrast.
