Type of article: Article

Summary

Condensation and mould growth are reported as being problems in an estimated 4.2 million dwellings in England. This paper examines the development of an algorithm, Condensation Targeter, to predict the relative humidity of internal surfaces and risk of mould growth in dwellings. Cold bridging, seasonal variations, variable moisture production and hygroscopic materials are studied. Results indicate that a steady-state model utilising Bredem-8 to predict internal temperatures and Loudon's condensation model to predict moisture shows good agreement with monitored data. Variations in occupant heating and density can be as important as ventilation in determining mould.
