What is a common consequence of inadequate ventilation in a facility?

Inadequate ventilation in a facility often leads to excess moisture. When there is not enough fresh air circulating, humidity levels can rise due to sources such as occupants, machinery, or even the building's structure emitting moisture. This accumulated excess moisture can create a breeding ground for mold and mildew and can lead to structural issues within the facility. It can also negatively impact the comfort and health of occupants, as high humidity levels can contribute to respiratory problems and other health concerns.

The other choices highlight concepts that are not associated with inadequate ventilation. Proper temperature control and enhanced air quality typically require adequate ventilation to ensure a balanced environment, while reduced energy consumption is usually a goal of efficient facility management rather than a direct consequence of poor ventilation.
