A little change of moisture content in thermal bridges (TBs) can lead to a big difference in heat and moisture transfer here as heat transfers more violently at TBs than the main part of walls. We aimed to (1)reveal the moisture distribution in the typical TB (i.e., wall-to-floor thermal bridge, WFTB) and its surrounding area, and (2) find high-risk areas for condensation. The transient numerical simulations lasted for two years were performed to model the moisture distribution. Simulated results show that the moisture distribution presents significant seasonal and spatial difference due to the WFTB, and the interface between WFTBs and the main part of walls has likelihood of condensation in winter.
