“…The monitoring technologies and procedures have been used in various operational scenarios, from planned conservation to safety measure of works of art exposed in museums (Accardo et al 1980;Bernardi et al 1985;Camuffo et al 2001;Litti and Audenaert 2018), historical palaces and churches (Aste et al 2019;Bonacina et al 2015;Fabbri, Pretelli, and Bonora 2019;García-Diego and Zarzo 2010;Gysels et al 2004;Muñoz-González et al 2018;Sileo, Gizzi, and Masini 2017), and natural sites (Bernardi, Todorov, and Hiristova 2000;Di Tullio et al 2010).…”

Most of the artistic heritage in the Mediterranean basin is hosted in rupestrian hypogeum whose peculiarity is given by the presence of at least one open side, which makes them particularly sensitive to meteorological conditions. This makes mandatory the monitoring of both indoor and outdoor environmental parameters to analyze the cause-effect relationship between microclimatic inside and outside the hypogeum. The paper proposes a spatial and temporal multi-scale methodological approach applied to a rupestrian church in Matera, which hosts precious wall paintings, particularly vulnerable to the effects of environmental parameters. The approach is based on the analysis of data acquired by three platforms: indoor, close-range outdoor, and outdoor data from a meteorological station and weather forecast from the COSMO 5 model. The method allowed to characterize the relationships between the indoor and outdoor parameters at different spatial and temporal scales. The results showed a significant correlation between the parameters, thus opening new opportunities for the monitoring of the rupestrian heritage based on the use of data systematically available, such as those from meteorological stations and meteorological forecast.

The correct storage and protection of works of sacred art, requires the guarantee of the optimal conditions of some parameters affecting the indoor microclimate of the place in which they are located. The temperature and humidity, are two of the most important parameters of the indoor microclimate. To avoid critical issues of the preservation process, these parameters must be kept constant during the day at each point of the place. In the conservation of works of religious art, there are two conflicting requirements: the use of the works themselves, and the need to protect the objects exposed to the deterioration, due at environmental factors. This can be achieved, by creating suitable conditions for their conservation. The arts work, usually are constituted by old materials that require for proper storage conditions depending on the type of material that constitutes them. In many cases, the ideal environmental conditions for the objects are not compatible with those most appropriate for the public. In this complex scenario the ecclesiastical monitoring, and its temperature and humidity control, exists a protocol unique accepted internationally, that establishing reference limits for the various parameters, and the only recommendations are contained in the (Italian Standardization body) UNI 10829/99. The most suitable approach, widely recognized is the "preventive conservation." This can be achieved through a mixture of measures and strategies, adapted to the case, aimed at minimizing the impact of environmental factors on the exhibited artifacts, to slow down the degradation. In this paper we present the results of a study focused on the use of wireless sensors for environmental monitoring. In this scenario with the use of the thermo-hygrometric sensors, you can realize systematic and adequate conditions.

“…The used painting technique is highly sensitive to humidity: unfortunately, the painting was subject for centuries to large and frequent changes in temperature and relative humidity [10]. High values of relative humidity caused the deterioration of the paintings on the Scrovegni Chapel walls (in Padua, Italy) [11,12] and wooden objects in Rosslyn Chapel (in Edinburgh, UK) [13,14]. Several other examples of artworks damaged by inappropriate microclimate can be found in [7,8].…”

A Proposal for New Microclimate Indexes for the Evaluation of Indoor Air Quality in Museums

A correct artwork preservation requires strict values of several microclimate parameters, in particular temperature, humidity, and light. In existing museums, the evaluation of the effectiveness of current building plant systems and management is essential to avoid artwork deterioration. In this work, we propose the use of five simple performance indexes that use monitored data to estimate the suitability of the whole museum system in the maintenance of benchmark values of temperature, humidity, and light. The new indexes also take into account microclimate daily span and spatial homogeneity, which can represent a criticality in the preservative process. We apply these new indexes to the results of a monitoring campaign in Palazzo Blu, a museum in Pisa, which lasted for almost four months during a temporary exhibition on Toulouse-Lautrec works. The indexes show a mainly acceptable instantaneous microclimate, but HVAC (Heating, Ventilating and Air Conditioning) system improvement is necessary to avoid high thermo-hygrometric daily span. This methodology is useful for the identification of microclimate criticalities and can help the cooperation between conservation experts and professionals giving hints to improve museum internal microclimate. In case ofalready optimal microclimate, these indexes can be useful in more complex analyses, including simulations of possible retrofit actions, keeping microclimate suitability as a constraint.Keywords: indoor microclimate quality index; museum; monitoring campaign; HVAC system On Microclimate for Artwork PreservationArtworks need strict microclimate conditions to be preserved. Each typology of artwork (e.g., paper, frescoes, paintings, stones) needs specific microclimate conditions for their preservation; in general, typical environmental parameters to be controlled are:• maximum daily and seasonal temperature difference ( • C);• mean relative humidity (%);• maximum daily and seasonal relative humidity difference (%);• maximum allowed illuminance (lx).For each type of artwork, standards suggest suitable microclimate intervals [1][2][3]; in some cases, however, if the artifact has been acclimatized to a particular historical climate environment, it is preferable to maintain these conditions instead of standard intervals, to avoid climatic shocks of the artwork [4,5]. Technical standard UNI 10829 [1] lists acceptable values for illuminance and optimal and acceptable ranges for temperature and relative humidity (in some cases, it is not possible to achieve, at the same time, visitor comfort and correct conditions for artwork preservation [6]). The presence of dust and gaseous pollutants and microbial and UV radiations can also threaten artwork integrity [7][8][9].
