16. Humidity control
Extremely low humidity is associated with the aerosolization of microbes and the persistence of dust, which can be irritating to the skin, eyes and mucous membranes. Conversely, high humidity is associated with the development of mold and other organisms that produce odors and can be irritating to sensitive individuals.
This feature requires buildings to provide humidification when relative humidity is low and dehumidification when relative humidity is high. This feature is dependent on local climate conditions and expected humidity.
Monitors measure 2 of the following pollutants in a regularly occupied space within the building, at intervals no longer than once an hour, and results are annually transmitted to the IWBI:
The following is required between showers and locker rooms, if present:
