Abstract

During the last century new heating systems were installed in most of our churches. However in this period it could be observed that valuable interior decorations, such as wall and ceiling frescoes, altars, windows and organs, suffer from a serious increase in damage and decay. Research showed the connection between indoor climate and degradation. The here presented study analysed the effects of different kinds of heating systems on the indoor climate, recording air temperatures and humidity in 26 churches in South Tyrol (Italy) continuously over a period of 4 to 8 weeks. The results showed characteristic temporal and spatial heat and humidity distributions, which were compared to the demands of the building and interior decoration in order to estimate potential risks and benefits. Hot air heating with short heating sessions showed up to be most harmful, whereas pew heating, hot air heating with a base temperature and floor heating had each their specific strengths and weaknesses. However, temporal and spatial heat and humidity distribution and their potential impact varied considerably for the studied churches with hot air heating. The detailed analysis of the influence of operation mode and time, outlet position, temperature of heating air and utilization frequency revealed that especially heating only for services in combination with wall outlets and short pre-heating time should be avoided.
