1. A method for reducing risks of airborne infection within a facility having a Building Management System (BMS) with a plurality of sensors disposed within each of two or more regions of the facility, the BMS configured to measure a plurality of different healthy building parameters that impact risk of airborne infection in each of the two or more regions of the facility, the method comprising:
a controller receiving values for a plurality of different healthy building parameters for each of the two or more regions of the facility as measured by the plurality of sensors disposed within each of the two or more regions of the facility;
the controller applying the values of the plurality of different healthy building parameters to a risk model that processes the values of the plurality of different healthy building parameters in order to ascertain:
an airborne infection risk score for each of the two or more regions of the facility;
an overall airborne infection risk score for the facility, wherein the overall airborne infection risk score for the facility is dependent on the airborne infection risk scores for each of the at least two regions of the facility;
a respective alert for each of the two or more regions of the facility when the corresponding airborne infection risk score exceeds a corresponding infection risk score threshold;
the controller displaying the overall airborne infection risk score for the facility on a dashboard;
from the dashboard, the controller accepting an input from a user to drill down to a selected one of the at least two regions of the facility, wherein responsive to receiving the input from the user, displaying the airborne infection risk score for at least the selected one of the at least two regions of the facility; and
responsive to a respective alert, the controller displaying the respective alert on the dashboard.
