          The existing building stock is responsible for 40% of the European energy use. One measure of improving old building’s energy efficiency is the application of thermal insulation, often at the interior façade surface. This alters the hygrothermal behaviour of the masonry and changes the risk for freeze-thaw damage. Besides, the durability of brick masonry is potentially affected by climate change. The latter, however, has not been studied widely. This paper presents a sensitivity analysis on the impact of climate change on the freeze-thaw risk in solid masonry. It is found that the freeze-thaw risk is generally decreasing in Brussels based on climate projections by the ALARO-0 RCM (RCP 8.5). Furthermore, the brick type is recognized as the most important variable when assessing the impact of climate change.
