Full-scale simulation of indoor humidity and moisture buffering properties of clay

It is important to control indoor humidity level in buildings as it influences occupant’s health and comfort. Some materials, when exposed to the indoor environment, help regulate relative humidity levels due to their capacity to absorb and desorb water vapour. The potential of earthen plasters to improve indoor comfort was investigated through experimentation and simulation. Results of clay moisture buffering capacity and computational simulation of the diurnal moisture variation in a clay plastered test room are discussed. This study compares measurement obtained in the laboratory with simulations output and identifies a discrepancy between the two methods in the quantification of the moisture buffering potential
