Abstract

Old buildings frequently present specific microclimates that do not always match the ideal conditions for the safe conservation of their materials, but that have been stable and consistent for a long time.In the last years several methodologies have been defined and the search by ideal values of temperature and relative humidity was intense, as is example of the UNI 10829. Presently the dynamic approaches are predominant, especially the methodologies presented in EN 15757 and in the ASHRAE specification (Museums, Galleries, Archives and Libraries).Despite the standardization and the numerous case-studies, the literature on the buildings in temperate climates is still scarce and the standard EN 15757 does not seem adequate to be used in all types of climates.This paper analyses the indoor climate of a thirteenth century church in Lisbon (Portugal) using the standard EN 15757, compares the data with other European case-studies and proposes a new method of analysis for temperate climates based on EN 15757 and influenced by the UNI 10829 and the ASHRAE specification.
