Moisture challenges in a changing climate

Research Project, 2024 – 2027

The projected climate changes foresee longer periods of warmer and more humid weather across Sweden during autumn, winter, and spring, which may increase the risk of moisture accumulation and mold growth in buildings. Rising summer temperatures may increase the need for cooling, even in residential buildings where cooling systems are not typically common, potentially altering the usual moisture pathways and increasing the risk of condensation in unexpected places. In the northern parts of the country, precipitation is expected to increase, while the western and southwestern regions may experience more frequent heavy downpours.

The project aims to improve understanding, knowledge, and preparedness for the challenges that a warmer and more humid climate may pose for the design and construction of new buildings, particularly with regard to new materials and material combinations. It includes a clear mapping and evaluation of future moisture risks for sensitive constructions and production stages, and provides guidance for simulation and assessment of these risks. The project will be carried out as a doctoral project at Chalmers University of Technology, aiming for a licentiate degree.
