Abstract

A new probabilistic model for the assessment of mould growth in buildings has been elaborated within interdisciplinary – building physics/structural engineering – cooperation. Both the occurrences of favourable conditions for the growth of mould fungi and their durations are taken into account. The probabilistic approach can be characterised as time dependent based on the theory of stochastic processes. The resulting probability of occurrence of mould growth cycles having deteriorating potential suggests itself as a measure of the mould growth hazard. By the measure, the management of building performance with respect to mould growth hazard may be conceived. The calculations of an illustrative example show that the variability of the outdoor climate conditions can substantially influence the occurrences and durations of favourable conditions for mould growth.
