Abstract

The applicability of IRT to assess the drying process of exterior walls after a long-term rainy period was evaluated through in situ tests. The physical phenomenon underlying these measurements was the effect of evaporative cooling, and the passive approach was implemented. Simultaneously, a moisture detector was also used to qualitatively assess the evolution of the moisture content of the walls. The walls under study were coated with similar rendering and painting, but they presented different exposure to solar and thermal radiation.
