Resumen

The presence of moisture in buildings can lead to pathological manifestations, and the behavior of materials when exposed to various conditions can be predicted through computational simulations. For this purpose, the hygrothermal characteristics of building elements are paramount. In Brazil, there is a gap in studies on the hygrothermal properties of materials, compromising simulations. This article discusses the possibilities of using European data in simulating moisture transport in ceramic brick walls in the southern region of Rio Grande do Sul, Brazil. The results were generated by comparing hygrothermal simulations with WUFI Pro 6.5 using the simulation program database with data collected from laboratory tests on ceramic bricks from a southern Brazilian brickyard. Tests for water vapor diffusion resistance, water absorption, and hygroscopic curves were conducted. Although both situations led to the growth of filamentous fungi, experimental data led to 3% lower values compared to database results. Regarding surface condensation, a likely higher occurrence was observed when using laboratory test data.

Hygrothermal Behavior of Ceramic Bricks from the Southern Brazil Brickyard

The presence of moisture in buildings can be responsible for the emergence of pathological manifestations. Through computational simulations, it is possible to predict how the material will behave when expossed to various conditions, and for this, the hygrothermal characteristics of building elements are of paramount importance. In Brazil, there is a gap in studies on the hygrothermal properties of materials, compromising simulations. This article presents the characterization of the hygrothermal properties of ceramic bricks from a brickyard in Southern Brazil, developed in collaboration with the LAMTAC - NORIE laboratory at UFRGS. Diffusion resistance, water absorption, and isotherm tests were conducted. The results of these tests were simulated in WUFI Pro 6.5 to compare them with the values available in the program's database for a brick with similar characteristics. When analyzing the growth of filamentous fungi, we noticed a 3% lower difference when observing the values in the database, indicating a higher probability of growth. Regarding surface condensation, we observed a maximum difference of 2.29 °C between simulated conditions, confirming a higher occurrence when using test data, especially when considering the minimum temperatures of internal facade surfaces.
