Design and evaluation of a dehumidifying plaster panel for passive architecture integration

Buildings Indoor Air Quality requires a control in the Relative Humidity
parameter. In passive architecture in humid climates relative humidity
is even more important for human comfort and difficult to control.
Therefore, nowadays, there is a research on dehumidifying systems.
The present article shows an innovative dehumidifying panel composed
of a plaster and Calcium Chloride salt. Laboratory tests are carried out
to establish its viability as an indoor air moister regulator integrated in
common plaster building interior coatings. There are two types of tests
that have been carried out in two consecutive empirical phases: in the
first phase, the tests of characterization of the Calcium Chloride as a
desiccant are carried out; in a second phase, the dehumidifying panel
as a whole is tested. Finally, both types of empirical tests show the
efficiency and viability as an air moisture passive control system.
