N2 - The avoidance of mould growth in dwellings is of worldwide concern. In England and Wales, the relevant Building Regulations guidance document recommends ventilation provisions to control both moisture and other pollutants in buildings. The performance criterion for moisture states that there should be no visible mould on external walls in a properly heated dwelling with typical moisture production. The relevant guidance document (ADF) further states that this moisture criterion will be met if the Relative Humidity (RH) in a room does not exceed 70% for more than 2 hours in any 12 hour period, and does not exceed 90% for more than 1 hour in any 12 hour period during the heating season. This paper presents initial exploratory results on the investigation of these performance criteria, which is a part of a much larger study relating to RH in dwellings. A number of experiments in a tightly controlled environmental chamber programmed to maintain suitable profiles of RH levels and temperatures which relate to typical surface conditions in dwellings in England and Wales have been carried out.
