What pressure should connecting offices to public garages maintain?

In the context of connecting offices to public garages, maintaining positive pressure is crucial for several reasons related to indoor air quality and safety. Positive pressure helps ensure that any airborne contaminants, such as exhaust fumes or automotive emissions that might emanate from the garage, are kept from infiltrating the office spaces. By maintaining a pressure higher than that of the adjacent garage, the airflow is directed outwards, effectively preventing the potential diffusion of harmful substances into the work environment.

Moreover, positive pressure can assist in controlling humidity levels and minimizing the risk of mold growth, which can be exacerbated by damp conditions typically associated with garages. It also contributes to maintaining a more comfortable environment within the office, making it more conducive for productivity and health.

In this scenario, the requirement for positive pressure aligns with various ventilation and health standards, which aim to secure the wellbeing of occupants in buildings adjacent to spaces that may have higher levels of pollutants. This practice is critical in designs that involve spaces with different usage levels and air quality needs.
