Skokloster Castle is a historic masonry building without any active climate control and hosting an important and heterogeneous collection of artefacts. Despite being cited as a good passive preservation environment, conservators are observing decay in the collections related to the indoor climate that may call for a re-evaluation of the climate control strategy. Air exchange is generally considered one of the driving forces influencing the indoor climate in unheated historic buildings. This study was developed to better understand and evaluate its influence on the indoor climate stability of the castle. The present study has outlined an experimental procedure for the assessment of the influence of air exchange that can be used in historic buildings in general. Air exchange rate was measured in seven rooms using tracer gas passive sampling. The results were related to an analysis of the variability of indoor temperature (T), relative humidity (RH) and mixing ratio (MR). A connection with short-term RH fluctuations, considered the most dangerous for hygroscopic materials, was identified. Problems connected with mould growth and high RH levels were also considered and discussed.
