Relative humidity (RH) is a crucial factor that can be significantly impacted by air infiltration in buildings.
Air infiltration refers to the unintentional leakage of outside air into a building, and it can have a profound effect on RH levels, leading to potential problems with water damage and indoor air quality.
When outside air infiltrates a building, it brings with it moisture. In cold weather, this moisture can condense on cold surfaces inside the building, such as windows and walls. This condensation can lead to mold growth, water damage, and other problems.
In warm weather, air infiltration can cause RH levels to rise, which can make the air feel muggy and uncomfortable. High RH levels can also provide a favorable environment for dust mites and other allergens, which can trigger asthma and allergies.
Controlling air infiltration is essential for maintaining optimal RH levels and preventing water damage. Several measures can be taken to reduce air infiltration, including:
The best measure of moisture in buildings is the RH level. RH can be measured using a hygrometer, which is a device that measures the amount of water vapor in the air.
RH levels should be maintained between 30% and 50% to prevent water damage and other problems.
Air infiltration can significantly impact RH levels in buildings, leading to potential problems with water damage and indoor air quality. By controlling air infiltration and maintaining optimal RH levels, building owners and occupants can help to create a healthy and comfortable indoor environment.
