Abstract: In this study, we investigate the impact of retrofitting intervention through adding super-insulation panels based on subcritical-dried (ambient pressure dried) aerogels as interior insulation on the hygrothermal performance of brick walls. The aim is to compare the hygrothermal performance of different wall configurations and to examine the effect of various design or climatic parameters. Simulations are carried out using WUFI and the mould growth index according to the VTT model is considered as the assessment parameter. Results are sensitive to the specific simulation cases. For this reason, a simulation-based multi-variable design assessment chart for mould growth risk is here proposed.
