What Causes High Humidity Levels in Commercial Buildings?
Excessively damp air is present in many areas of the United States. Approximately half of the nation’s population experiences a “moist” climate and 25 percent live and work in a “humid” climate zone. Other contributing causes of moisture inside a commercial facility include water that leaks through the building envelope (the physical barriers that separate the conditioned and unconditioned environment), leaks from the plumbing system, moisture retained in construction materials, and damp ground underneath the structure.
The Importance of Humidity Control in Commercial Buildings
Generally, a relative humidity level of 20 to 60 percent is optimal in most commercial facilities. Keeping the humidity within this range will maximize occupant comfort and prevent excessive moisture in the air that can foster mold growth. Implementing efficient building humidity control measures is essential for removing moisture and creating a drier indoor climate.
