Relative humidity (RH) is the measure of how much moisture is in the air compared to the maximum amount of moisture the air can hold at a particular temperature. It is expressed as a percentage, with 100% being the maximum amount of moisture the air can hold at that temperature.
For example, if the air is holding half the amount of moisture it can hold at a given temperature, the RH is 50%. If the air is holding all the moisture it can hold, the RH is 100%.
Relative humidity is important to understand in a building because it can have a significant impact on indoor air quality, occupant comfort, and the integrity of the building itself.
If the relative humidity is too low, it can lead to dry skin, respiratory problems, and the drying out of wooden furniture and other materials in the building. On the other hand, if the relative humidity is too high, it can lead to mold growth, musty odors, and damage to the building's structure.
For example, during the winter months, the relative humidity inside a building can drop to very low levels due to the use of heating systems. This can lead to discomfort and dryness of the skin and respiratory system, and can also cause wood floors and furniture to shrink and crack.
Similarly, in the summer months, high humidity levels can make the air feel heavy and uncomfortable, and can promote mold growth if not properly controlled.
In conclusion, understanding relative humidity in a building is important to ensure occupant comfort, maintain indoor air quality, and protect the integrity of the building and its contents.
