Potential effects of permeable and hygroscopic lightweight structures on thermal comfort and perceived IAQ in a cold climate

In this study, the importance of moisture exchange for indoor climate and moisture conditions in permeable and hygroscopic structures by means of a all-year-round dynamic simulation along with measurements in a typical Finnish one-storey detached house with mechanical supply and exhaust ventilation
Their conclusion is tha permeable and hygroscopic strucutres can significantly reduce peak relative humidity (RH) values and daily changes in RH, but with a short term effect.
However both simulated and measured results show that moisture exchange is important enough to be taken into account in future simulation tools.
