Procedure for evaluating the historical climate using the example of the Hluboká nad Vltavou state castle

Alena Selucká

Long-term records of relative humidity and temperature are one of the main parameters for analyzing climatic conditions inside buildings. The recently issued European standard EN 15757 from 2011 introduces a new methodology for the evaluation which is based on a concept called the "historical climate". This principle is based on the assumption that the risk of physical damage to organic hygroscopic materials due to fluctuations in humidity and temperature that do not exceed the verified range (within which the items are long acclimatized) is very low. The methodology for establishing the historical climate has been applied in selected areas of the Hluboká nad Vltavou state castle with the aim of assessing partial climatic conditions of the castle installation. The study makes available evaluation procedures of seasonal cycles of acceptable and risky short-term fluctuations in relative humidity and temperature. As part of routine measures for regulating the measured parameters, it points out the need to protect and ensure the stability of installed items and equipment before visitor comfort. In this context, the issue is discussed of providing access to historical buildings in winter and the possibility of tempering or heating them.
