“…The developed methods for the rational combination of electro osmotic drainage of walls and controlled air exchange can reduce the drainage time of high moisture building envelopes to sufficient moisture within 4-18 months and preserve historical layers and murals. Selfregulation of aeration air exchange [16,17] creates permissible meteorological [18] conditions in temples. And this will ensure the safety of historical and architectural monuments for decades.…”

The paper devoted to indoor air quality providing in orthodox churches in Russia. Using the results of theoretical and experimental research made some practical recommendations for design and installation of ventilation systems in orthodox churches. Significant part of research deals with air and constructions humidity controls by reverse osmosis. It is reaffirmed that the rate of dehumidification is directly connected with the air exchange rates and operation of space heating devises in premises. It is very common to use natural ventilation in old churches. It is very easy to install and maintain, but still this way of indoor air conditions providing is absolutely not sustainable. And to avoid the leak of ventilation efficiency for different rooms it is recommended to provide mechanical supply and exhaust ventilation. Another significant issue for providing rapid wall dehumidification is properly operating space heating. It is noted that heating should be combined with an action of ventilation and electroosmotic drying.

Effects of Visitor Influx on the Indoor Climate of the Milan Cathedral

et al. 2023

The indoor climate of non-climatized churches is usually subject to cyclical fluctuations of temperature and relative humidity induced by external climate conditions which might be dampened by the high thermal capacity of their envelope. However, several phenomena affect their indoor climate (e.g., internal gains due to people and artificial lighting, air infiltration, etc.), which lead to environmental variations that might jeopardize the artworks contained within. In particular, one of the most influential parameters that may affect non-climatized churches is the massive and intermittent presence of people who constantly visit their spaces. In such regard, long-term monitoring allows the collection of environmental data with different building operation conditions and visitor fluxes. This paper analyses the indoor climate of the Milan Cathedral (Duomo di Milano) in Italy for three continuous years (including the lockdown period that occurred in 2020 caused by the COVID-19 pandemic), with a focus on visitors’ effects on the indoor environment and the conservation of the main artworks contained within. The results of the analysis have shown that spaces with huge volume are most influenced by the opening of the doors rather than the hygrothermal contribution of the intermittent presence of massive crowds. Moreover, the absence of visitors for a prolonged period correlates with an improvement in the indoor conservation conditions for artworks, especially those made of hygroscopic materials, due to the reduction in short, rapid climate fluctuations.
