    Abstract - (Show below) - (Hide below)

    Provides simplified calculation methods for: a) The internal surface temperature of a building component or building element below which mould growth is likely, given the internal temperature and relative humidity. b) The assessment of the risk of interstitial condensation due to water vapour diffusion.
