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.
