“…[27,29]; therefore, appropriate techniques should be introduced to produce energy savings and to ensure good dynamic microclimatic control [4,30]. In recent years, many studies have been published on balancing energy and conservation needs [6,9,27,[30][31][32][33][34][35][36][37]. Ascione et al [9] and Kramer et al [34] achieved energy savings of approximately 40% and 77%, respectively.…”

In museums, poor microclimate conditions, especially large changes in relative humidity and temperature, can lead to serious deterioration of the exhibits. Properly designed heating, ventilation, and air conditioning (HVAC) systems for precise control of the air parameters are required. However, due to the financial restrictions of museums, complex air-conditioning systems are often not feasible. In this study, we tested and propose novel methods to reduce the short- and long-term fluctuations in the relative humidity in exhibition rooms of a Polish museum. The methods only include indoor temperature and ventilation airflow control strategies, without the use of (de)humidification equipment. The analysis is based on simulations using EnergyPlus software. A multi-zone thermal model of the museum building was validated and calibrated with measured data. A full calendar year was simulated for five control cases (including the current method used) and two internal heat gain schedules. The energy demand for heating and cooling for each case was calculated. The combination of temperature control and adequate ventilation using ambient airflow allows for dramatic improvement in the microclimate conditions. The proportion of the year when the instantaneous indoor relative humidity is ±5% from set point decreased from 85% to 20%. A significant effect was obtained over the summer months.

“…Otherwise, erroneous conditions of conservation of objects might be taken for granted. This suggestion is reinforced by previous researches on the subject [9,[32][33][34][35], which pointed at learning from the historic indoor climate conditions and also at the history of building itself and its different construction phases.…”

The importance of long-term hygrothermal assessment of museum spaces: method and application in a permanent exhibition in a historical building

This paper presents the analysis of the hygrothermal conditions of a museum space hosted in an 18th century building, in Coimbra (Portugal). This historical building, which houses the Science Museum of the University of Coimbra, is located in the historic centre of the University of Coimbra, officially declared a World Heritage Site in 2013 by UNESCO. The methodology proposed in EN 15757:2010 was applied to two monitoring campaigns carried out at a distance of 4 years, in two of the rooms of the permanent exhibition. The results of the monitoring periods are presented and discussed. The findings unveil the necessity for long-term monitoring of the indoor environmental conditions of museum spaces, towards the support of grounded based-evidence guidelines for the conservation of objects and quality of environment for exhibits conservation. Resumo Neste artigo são analisadas as condições higrotérmicas de um espaço museológico situado num edifício do século XVIII, em Coimbra (Portugal). Este edifício histórico, que acolhe o Museu da Ciência da Universidade, localiza-se no centro histórico da Universidade de Coimbra, declarado oficialmente como Património Mundial em 2013 pela UNESCO. A metodologia proposta na norma europeia EN 15757:2010 foi aplicada em duas campanhas de monitoração realizadas a uma distância de 4 anos, em dois dos espaços da exposição permanente do MCUC. São apresentados e discutidos os resultados dos períodos de monitorização. As conclusões mostram a importância da monitorização das condições ambientais internas dos espaços museológicos a longo prazo, no sentido da elaboração de diretrizes de conservação de objetos e da qualidade do ambiente interior para a conservação de exposições, suportadas e baseadas em evidências.

“…The conservation history of the painting prior to the foundation of the Gallery is unknown. However, the building in which the painting was stored and exhibited was a repurposed structure [24] before reconstruction concluded in 2017, sharing typical conservation conditions with other gallery and museum buildings built in the first half of the twentieth century. Being unmaintained and without air conditioning-with visible damage to the structure and traces of humidity influx, lack of insulation, and often large window areas-these buildings are characterized by sudden, drastic changes in temperature and relative humidity (especially in the exhibition spaces), which causes damage to paintings and results in cracking.…”

Identification of Lithol Red Synthetic Organic Pigment Reveals the Cause of Paint Layer Degradation on the Lazar Vozarević Painting “Untitled” with Copper Plates

Out of a total of 56 paintings in the collection of the Lazar Vozarević Gallery in Sremska Mitrovica, only one Lazar Vozarević painting from 1961, titled “Untitled”, has been subject to atypical degradation that has resulted in damage of completely atypical appearance. Such a problem had never before been noticed in Yugoslavian paintings of the 20th century. Discolored areas were found in various locations on the paint layer of the painting “Untitled” (especially on the lower and central parts of the painting), which disturbed the visual experience of the artistic work. To discover the cause of this discoloration, the composition of the paint layer was investigated, with the assumption that the true cause of degradation was hidden therein. Moreover, this painting belongs to a specific period in Vozarević’s activity, characterized by the use of non-traditional painting materials. To identify pigments from the highly degraded painting “Untitled”, scanning electron microscopy coupled with energy dispersive X-ray spectrometry (SEM/EDS) and micro-Raman spectroscopy were applied. Lithol red, a synthetic organic pigment known to give paintings a red tone, was identified as the main reason for the painting’s degradation. Lithol red is not only highly light-sensitive but is also chemically unstable, toxic, and sensitive to heat.
