“…Such temperature and humidity conditions are conducive to the growth of fungi. Moreover, studies have reported that unsuitable temperature and relative humidity lead to mechanical, biological, and chemical degradation of cultural relics ( Pinzari et al, 2020 ; Sadlowska-Salega and Radon, 2020 ). Currently, heating, ventilation, and air conditioning systems are the main methods used to meet the requirements of heat and humidity ( Ferdyn-Grygierek and Grygierek, 2019 ; Schito et al, 2020 ).…”

In April 2020, 232 tombs of the Western Han Dynasty were found in Sundayuan, Heze City. In total, 141 pottery figurines of significant historical, cultural, and artistic value were unearthed from the tombs. Some of the figurines are currently being stored in warehouses, and the surface of some of the figurines show fungal deterioration. To thoroughly analyze the fungal deterioration on the surface of the pottery figurines and find appropriate control methods, we used high-through sequencing, scanning electron microscopy observation, pure cultures of culturable fungi, and optical microscopy observation and molecular identification of culturable fungi. We conducted fungistatic and simulation experiments in the laboratory to find appropriate control methods. We found that the fungi on the surface of the figurines were mainly of the phylum Ascomycota, and a few fungi were of the phyla Basidiomycota and Mucoromycota. We isolated seven culturable fungal strains and observed their colony morphology. The seven fungal strains were Lecanicillium aphanocladii, Penicillium aurantiogriseum, Clonostachys rosea, Mortierella sp., Mortierella alpina, Aspergillus flavus, and Cladosporium halotolerans. Through the fungistatic and simulation experiments conducted in the laboratory, we found that 50 mg/ml cinnamaldehyde and 0.5% K100 (2-methyl-4-isothiazolin-3-one) have a good fungistatic effect. They can not only inhibit the growth of fungi on medium, but also inhibit the growth of fungi on the surface of pottery figurines. This study has good reference significance for the analysis and control of fungal deterioration of unearthed pottery figurines.

“…It should be noted that the used software was extensively validated for various building typologies and structures. A detailed validation of the hygrothermal WUFI ® plus model can be found in [71,72]. In particular, in a very complex system of boundary conditions, and with a large number of unknowns, it was possible to achieve high compliance of the model with the measurements.…”

“…In particular, in a very complex system of boundary conditions, and with a large number of unknowns, it was possible to achieve high compliance of the model with the measurements. Despite the application of well-validated software and carefully defined boundary conditions, no precise reflection of real hygrothermal behaviour of partition could be achieved [72]. However, even in very complex buildings, sufficient model compliance can be achieved:…”

The paper presents an analysis of the hygrothermal performance of an inverted flat roof with a CLT (cross-laminated timber) structure in a building that meets the requirements of Passive House Standard (PHS) with regards to the potential risk of moisture. The calculations were made in the WUFI®Plus and WUFI®Bio software. The following variants were taken into account: three structure configurations, three different external climates and different scenarios of microclimate control and air change rate. The results of the calculations show that, especially in cooler climates, there is an actual moisture risk in the structure despite the excellent thermal insulation. The structure of the inverted flat roof, due to the use of a tight membrane on the outer side, allows for the partition to discharge the excess moisture only to the inside of the building. Ensuring the comfort of users may require periodic humidification of internal air, which translates directly into an increase in moisture content of the structure. The performed analysis clearly showed that there are no universal solutions. It is important to point out that for the proper performance of inverted wooden roofs, it is crucial to analyse moisture, not only thermal and energy parameters.

“…Interestingly, [15] presents a multi-objective optimization methodology that guides managers of museums to improve artwork preservation using, in this case, a TRNSYS 17 model [16], where the model becomes a key element to provide insights to the optimization solver. Monitoring and understanding the building through a model becomes a key element enabling analysis of the thermal performance, as well as validations [17] to verify its suitability for containing historical pieces of art.…”

The purpose of this study is to determine Girona Cathedral’s thermal performance and to verify that it is suitable for containing historical pieces of art. We present the results of our analysis of the indoor thermal conditions during the period from January 2011 to December 2016. Real data were collected from strategically located probes inside the cathedral and from an outside weather station. The results were compared with an EnergyPlus computer model to verify the calculations and improve decision making. The model considers the envelope’s thermal inertia, the characteristics of the enclosure, and the passive systems for performing thermal analysis. The cathedral’s indoor environment is very stable. Because of a high capability of thermal-energy accumulation, a one-month thermal lag between indoor and outdoor temperatures exists. Furthermore, the maximum and minimum temperatures are dampened, with a two-degree variation above or below the outdoor average, depending on the season. The outdoor humidity can vary from 40% to 100% daily, whereas the indoor humidity variation is around 5%. This indoor stable condition protects the artistic objects in the building. This six-year monitoring and analysis allows for the determination that high-inertia buildings are suitable for displaying and preserving pieces of art and antique furniture, protecting them from deterioration.
