Abstract: | In December 2002 a wall heating system came into operation in the Renatus Chapel in Lustheim near Munich. By comparing climatic data of several years we hope to be able to assess the changes in climate as a result of the chapel's renovation and the installation of the wall heating. These will be placed in context with current research in the field of preventative conservation. The paper will focus on the reactions of the artefacts, as well as on soluble salts and the environmental conditions for mould growth. Part of the results will be evaluated in the form of a risk assessment. A new method for measuring climate in sealed cups has been implemented in order to determine the direction of water vapour flux through the walls and floor of the chapel. Statistical analysis of the data will show the range of variation in the indoor climate both before and after the wall heating was installed. The air exchange rate has been determined for different weather conditions. Together with a theoretical indoor relative humidity, calculated from the outdoor moisture content, this reveals information about the strength of influence of the external climate. Finally the results will be discussed from the perspective of conservation science. Based on the conclusions of this thesis, suggestions will be made for the optimization of the building and the wall heating. |
