Abstract
The construction industry consumes vast materials and energy, contributing to CO2 emissions. Reintroducing landfilled industrial waste into production aids carbon neutrality but poses challenges like unknown hygrothermal performance. This study numerically assesses façade sandwich panels with waste-based thermal mortar core, comparing them to EPS-core panels using WUFI Pro software. A special focus was put on the behaviour under different climates and coating solar absorption. Results show higher solar absorption reduces moisture content, while surface temperatures depend more on absorption than construction type. Waste-based panels lower exterior condensation risk but retain more moisture and exhibit higher thermal lag. Overall, they perform better in temperate than colder regions, highlighting the potential and limitations of waste-based façade materials.Keywords: Façades, Sandwich panels, Industrial wastes, Numerical simulations, Hygrothermal performance
