“…Indoor microclimatic conditions play a key role in the conservation and maintenance of heritage volumes, and their control is necessary in order to limit the processes of damage and subsequent restoration work while also increasing their patrimonial value [1][2][3][4][5][6]. Library collections consist of a wide range of hygroscopic organic materials (paper, leather, parchment, cloth), which are climate-sensitive and vulnerable to the process of deterioration.…”

The Sala del Dottorato (Hall of Graduates) is a magnificent library in the University of Perugia which plays the double role of providing optimal conservation of valuable books and manuscripts while also hosting important events. This double role is closely connected to contrasting indoor microclimatic conditions. This paper presents the results of a multidisciplinary study, begun in 2019, which investigates optimal conditions for the conservation of volumes by monitoring thermo-hygrometric and air quality parameters. The study describes the current conditions of the Hall (in terms of air temperature, relative humidity and concentration of CO2), highlighting critical aspects, defining strategies for their mitigation and control, and outlining future developments. Improvement measures relate to the installation of a permanent monitoring system with alarm settings and data storage, technical interventions on the windows, and the restoration of several volumes. The paper shows the importance of monitoring as an instrument of control in real time and provides guidelines for management to be implemented according to indoor microclimatic conditions.

“…In order to define the relationship between environmental conditions and heritage risks, the above studies involved both outdoor and indoor climates. In this context, each degradation phenomenon was investigated through monitoring and evaluating thermo-hygrometric parameters [10] [11] [12] [13] [14] [15]. The outcomes of these experiments contributed to the development of Italian [16] [17] [18] and European [19] [20] [21] standards which offered some recommendations concerning monitoring, processing, and summarisating procedures for taking the "historical climate" into consideration [8].…”

The common approach for libraries to preserve their paper-based collections from irreversible deterioration is by controlling quantitative parameters, such as temperature and relative humidity.Variations of these parameters for preventive conservation can be expressed by the "performance index" (PI) and the "amplitude index" (AI).Building envelope is the first filter of the external climate, buffering the external weather fluctuations and maintaining the building's indoor climate stable. Its shape, window areas and envelope materials are the most influential parameters. As they capture the relationship of a few geometric and physical variables with the building's performance, the envelope characteristics can be expressed as certain passive envelope indexes.This paper studies the relationship of certain passive envelope indexes and the preventive conservation indexes for books for several libraries and archives located in La Plata, Argentina.The results show the impact of every passive envelope index upon the preventive conservation indexes. The compactness, heaviness, adjacency to spaces and adjacency to ground have a positive linear correlation meanwhile transparency and global transmittance are parameters with a negative correlation. In general, the most influential parameter is the relative area adjacent to other spaces, followed by global transmittance, transparency, heaviness, relative area adjacent to ground and compactness. Highlights  Definition of passive envelope indexes and caracterization of libraries in La Plata  Environmental monitoring: achievement of preventive conservation indexes  Correlation between passive envelope indexes and preventive conservation indexes  Determination of the most influential passive envelope indexes for the achievement of preventive conservation indexes.

“…Since T is highly related to RH values, 5-6% decrease in RH is expected for the same time period (Giorgi and Lionello, 2008;Polade et al, 2017). Therefore, changes in microclimate conditions (T and RH) in Mediteranean climate zone have the potential to cause damage on paper-based collections and result in poor thermal comfort in historic libraries, especially for those without an air-conditioning system (Bülow, 2002).…”

Most historic library buildings house valuable paper-based collections that are kept in unconditioned environments. This vulnerable cultural heritage is expected to be highly affected by climate change in the future. In this study, indoor microclimate of an unconditioned historic library, Necip Paşa Library (Izmir, Turkey) is analysed for existing conditions and future climate data. The measured and predicted indoor microclimate data from 'present' till 2080s are used to determine possible chemical degredation risk on library collection and human comfort. Comparison of periodic results of future climate data indicates an increase in temperature that could cause both an increase in chemical degredation risk on the library collection and a decline in thermal comfort conditions. Mitigation of climate change effects on library collection and human comfort requires taking some actions such as adding light and adaptive mechanical solutions.
