This session explores strategies for improving the thermal performance of historic masonry buildings. It focuses on the risks of interior insulation, including condensation and freeze-thaw damage. Hygrothermal modeling with future climate data is used to assess the durability of different approaches. Case studies illustrate how to balance energy efficiency with long-term preservation of heritage structures.
