The importance of the climatic control in museums

Abstract

Among the principal climatic factors that cause interferences in the collections and have to be controlled by the climatization system are the temperature, absolute humidity, saturation and condensation. Throughout tracking of the exposed etnographic collection at the Museum of the Cultures Don Bosco it was verified the occurrence of infestation by fungi. The presence of these organisms has indicated that the artifacts were susceptible to permanent damages and of difficult restoration, because of the fast rate of reproduction of these organisms in favorable conditions and the way that they use the substract for feeding. In this way, the administrative team joined to the technical team decided to anticipate the installation of the climatization system of the permanent exposition hall. Besides the installation of climatizators, many measures were established together with the control and maintenance of the established temperature and humidity.
