Abstract

The hygroscopic structures can significantly smooth down the changes of the indoor air relative humidity under dynamic loads. During the room occupation period moisture tends to flow into the hygroscopic structures that are warmed up due to the latent heat effect. This warming can temporarily change the direction of heat flows, which may improve the indoor thermal comfort and energy efficiency. When applying high density cellulose insulation on the inner parts of the structure, the indoor moisture buffering effect could be improved. Highly insulated structures enhance the humidity interaction with indoor air.
