“…Usually extensive air conditioning is implemented to provide such strict control of the interior environment. That does result in a substantial energy consumption though, which is economically and ecologically inopportune, even despite efforts in the direction of 'low-energy museal spaces' [11][12][13][14]. As an alternative the 'passive conditioning' concept is currently being developed and promoted [15][16][17]: a storage with a high thermal and hygric inertia enclosed by an envelope with high thermal and hygric resistance should sufficiently stabilise the interior climate, with resultantly (virtually) no need for mechanical air conditioning.…”

Despite the large economic and ecologic costs, museum storage spaces are often equipped with extensive air conditioning, to provide the desired stable interior climate. The new "passive conditioning" paradigm aims at resolving these costs: a high-hygrothermal-inertia building with a high-hygrothermal-resistance envelope is to satisfactorily stabilise that interior climate, with no need for mechanical air conditioning hence. This paper first studies the reliability of full passive conditioning for museum storage spaces. It is shown to be an illusion, since it usually results in excessive interior humidities. Auxiliary dehumidification is thus required to provide good conservation conditions, and it is secondly investigated how the dehumidification load can be diminished. The study reveals the crucial impact of air tightness, while thermal insulation only has a minor influence. To further reduce the economic and ecologic cost of conditioning, the paper finally assesses "concentrated dehumidification": dehumidification during a part of the day only, while leaving the humidity free-running during the rest of the day. It is established that the hygric inertia of the interior air, building walls and stored objects keeps the fluctuations of the interior relative humidities to a minimum when considering adequately air tight museum storage spaces.

“…The assessment is carried out by monitoring temperature and relative air humidity [9][10][11][12] as well as CO 2 concentration, the latter being an indicator used to evaluate heat gains from the visitors [13], and the quality of the ventilation in the building [14]. Particular attention should be paid to sharp peaks in temperature and air humidity, because instantaneous acute changes in these parameters are dangerous to the exhibits.…”

“…Impact of the external climate on the indoor environment in museums or other historical sites, e.g., churches, are focused on dust and gaseous pollutants transport from outside to inside [8,[19][20][21][22][23][24][25][26][27][28] but also on the impact of hygrothermal external conditions on the indoor climate [29][30][31][32][33][34][35]. Recent studies [19,25], shows that a particularly unfavourable situation is when a museum is located in the centre of the city because pollution from traffic penetrates inside the museum.…”

“…Other studies [8,23] shows that the pollutants are also transported to the indoor environment by visitors. In turn, Papadopoulos et al [29] presented the variation of the indoor and the outdoor air temperature and relative humidity values in the Museum of Byzantine Culture in Thessaloniki for two typical days during the cooling season. They reported that in a typical summer day, the indoor air conditions cannot be characterized as satisfactory, mainly due to the high relative humidity levels.…”

Hygrothermal Risk in Museum Buildings Located in Moderate Climate

Works of art are sensitive to environmental factors—mainly temperature and relative humidity—which, when stable, are generally recommended as ideal protection conditions, but in historical museum buildings, the required conditions are difficult to maintain, due to a lack of adequate heating, ventilation and air-conditioning systems. The paper presents the analysis of one-year measurements of temperature and relative humidity in three different museums in Poland. The aim of the research was to identify the risk to museum collections, due to unbalanced moisture loads and unstable indoor air temperatures, as well as to identify possible causes of fluctuations in these parameters. This article focuses on assessing the impact of variable external and internal loads on the hygrothermal parameters of indoor air. The profile of internal hygrothermal loads in exhibition halls varied over time, which resulted in a temporary variation of the indoor environmental parameters. The lack of appropriate systems, shaping the microclimate in the analyzed museums, and the lack of automatic control in existing devices did not allow to maintain the temperature and relative humidity within appropriate limits. In the museums, the maximum indoor temperature values were higher than those recommended in the requirements. Relative humidity values in all museums exceeded the recommended range both above and below.
