Humidity control

Intent: 

To limit the growth of pathogens, reduce off-gassing, and maintain thermal comfort by providing the appropriate level of humidity.

A ventilation barrier is an air barrier consisting of a continuous membrane that has documented resistance to air leakage; it aims to minimize migration of heat, moisture or contaminants from high to low humidity spaces.

Similar to vestibule, an airlock is an interim space between the shower rooms and the adjacent occupied spaces that has two gas-tight doors; it aims to minimize migration of heat, moisture or contaminants from high to low humidity spaces.
