Abstract (EN): This article describes the recent research conducted at LFC-FEUP on the subject of moisture buffering and its contribution to the hygroscopic inertia of a room. An extensive experimental campaign complemented with numerical simulation provided the main results of that research. The characterization of painted renderings properties provided a deeper insight on the buffering potential of common finishing solutions. The experimental assessment of hygroscopic inertia at room level was implemented using a flux chamber designed specifically for this experiment. A daily hygroscopic inertia index, Ih,d, was defined using MBV as a basis for the assessment of materials contribution to the buffering capacity of a room. The correlation between that index and peak dampening was proved both numerically and experimentally. The benefits of daily hygroscopic inertia were analysed with the help of full hygrothermal simulation of a bedroom. KEYWORDS: Moisture Buffering, Hygroscopic Inertia, Experiments, Simulation
