For preservation of artefacts in a museum the indoor climate is often restricted to a very narrow interval for temperature, but most of all for relative humidity. In old buildings the museum conditions of artefacts, e.g. near cold walls, mostly are not in line with museum recommendations.To have an impression of indoor museum climates in old buildings, a large number of case studies were carried out in several Dutch museums. For at least one year, temperature and relative humidity were recorded in different rooms and at different external wall surfaces of the museums. The results of this measurement campaign reveal that there were a large number of indoor climate conditions that did not satisfy the originally formulated restricted climate.
