Humidity buffering


Humidity buffering refers to the ability of materials to moderate changes in relative humidity by absorbing and desorbing water vapour from surrounding air. This is also referred to as moisture buffering.
The phenomenon has long been exploited for preserving items from damage that could be caused by either excessively moist or dry conditions.

Examples

Recently, there has been an interest in the field of building science and architecture in using humidity buffering as a passive indoor climate control, thus reducing the need for air conditioning and ventilation.
