Man made climate change on earth is a fact widely agreed on. The changing exterior conditions are not only affecting the buildings exterior surface, but also the resulting climate on the inside of the building. Especially in case of sensitive interior, like in cultural heritage buildings, this may lead to new challenges in the future. This paper presents an exemplary approach to assess the influence of changing exterior climate on the inner climate and thus on the interior of the building. A weather data set containing modelled values from 1960-2100 is compared to measured climate data within the same region. A methodology using descriptive statistics for the comparison of the modelled and the measured climate data is developed. After calibrating the modelled climate data the whole modelled weather dataset is processed as input for hygrothermal building simulation. A simple stone church in the region of interest is modelled. The hygrothermal building model is calibrated with past measured interior climate data. The successfully calibrated building model is then combined with the long-time climate file to predict interior climate conditions under the influence of climate change. Hygrothermal building simulation allows not only to assess the changes in building energy use but also in comfort conditions (which is, besides for people, "comfortable" for the valuable interior).
