A simple generalized mass transfer model for evaluation of the environmental performance of archival boxesMarkelj, Jernej (Avtor) Grau-Bové, Josep (Avtor) Kraševec, Ida (Avtor) Vereecken, Evy (Avtor) Strlič, Matija (Avtor) humidity attenuation (HA) indexarchival box performancepreventive conservationmass transfer modelEnclosure materials can have a variety of properties that moderate relative humidity (RH) in relation to external RH fluctuations. In this study of different constructions and board types we developed a simple empirical model to predict the relative humidity damping capacity via a Humidity Attenuation (HA) index. A multiple linear regression model was built to predict the HA index based on the material/box properties. The results indicate that at low ventilation rates, vapour permeability has a similar (but opposite) effect to moisture buffering and that stacking boxes or filling them with paper significantly improves the enclosure’s RH damping capacity. This work will provide a more realistic assessment of the suitability of museum enclosure microenvironments with respect to RH moderation. To increase applicability in practice, a decision-making tool (an online app) was developed for curators and conservators to support preventive conservation measures.20252025-08-08 12:17:21Članek v reviji171140sl
