Heat and mass transfer modelling for moisture related risks in walls retrofitted by timber materials.

This is the presentation given at the 5^th IBPSA Italy Conference "Building Simulation Applications" (BSA 2022), regarding the hygrothermal behaviour of the e-CLT retrofit solution developed in the Horizon 2020 Project "e-SAFE". The presentation shows that in Milan (Northern Italy), a moderate mould growth risk occurs in the wood fibre, while no risk occurs in the CLT. The liquid water (LWC) kept inside the wooden materials increases the U value by around 10% if compared with dry materials. The presentation also discusses some issues regarding the reliability of the weather data and the hogrothermal properties of CLT.
