Coupled Heat And Moisture Transfer Simulations On Building Components Retrofitted With A Newly Developed Aerogel-based Coating

The study investigates the effectiveness of an energy retrofit strategy based on the adoption of an aerogel-based coating aimed at mitigating thermal bridges and reducing energy losses. The material was developed and characterised in the framework of the Horizon-2020 project ‘Wall-ACE’. The analyses were aimed to validate coupled heat and moisture transfer simulation models at the component level through the comparison with in-field experiments. Furthermore, the results achieved by the heat and moisture simulations were compared with those obtained by means of standardised simplified methods to verify if the adoption of more accurate calculation procedures gives different results.
