Moisture and mould in buildings have become fairly common problems in Italy, particularly since regulations aimed at energy conservation have been enforced in the seventies. Results of a case study conducted within IEA Annex XIV are presented in this paper. Two flats belonging to the same building (one with and the other without moisture problems) have been monitored during the winter 1987-88. Indoor temperature and air humidity, wall surface temperature and weather parameters were recorded for several weeks using two automatic data loggers.
Annex 14 -Condensation and Energy- started in April 1987, with a take of meeting in Utrecht, The Netherlands. The annex itself was born after a moisture-workshop in September 1985 at the Laboratory of Building Physics, KULeuven, Belgium.
The research was intended to discover which species of mould occurred, whether there were different species on the same spot or whether one species was dominant, whether the species were different from one dwelling to another or whether the same species occurred in all the houses, and whether there were differences according to the furnishing materials used or the presence of fat, for example on kitchen walls.
