Development of a zonal model to assess indoor climate and damage risks to art works in church buildings

Most of the degradation of works of art in historic buildings is caused by unfavourable indoor climate conditions. The most important works of art receive invasive conservation treatment, called direct action, but this treatment is very expensive. To avoid invasive conservation treatments and ensure that works of art are protected for now and for the future, indirect action to mitigate the deterioration process is necessary. This holds that exposure to unfavourable indoor climate conditions should be avoided, as far as is compatible with its social use.
