Abstract:	This thesis is part of the studies of durability and degradation of façade, especially related to exposure conditions of the building, with emphasis on climatic actions of external origin as degradation agents. In studies on façades degradation, the hygrothermal variations are among the main mechanisms responsible for the natural aging of the buildings. There is a major barrier to the advance in the study of durability and degradation of façade systems. This barrier refers to the lack of data available for a more detailed analysis of the natural aging, as results of climatic agents and degradation mechanisms. The overall objective of this thesis was to evaluate the influence of climatic degradation agents in the hygrothermal behavior of porous vertical systems (ceramic block masonry and facing by mortar), in Brasília-DF, based on the action and interaction among agents external climate origin and façade element, in each of the eight main orientations façade over the dry and rainy seasons of the year. Through computational tool for hygrothermal simulation WUFI Pro 5.3, there have been studies of hygrothermal behavior of the porous facade system. With the results, it was possible to establish a relationship between dose and response, based on the agents and degradation mechanisms related to hygrothermal variations of building system studied. The results showed that the facades are influenced climate actions in different degrees of intensity and frequency, depending on the hygrothermal properties of the components and the cyclical and seasonal variations in climatic agents that affect the hygrothermal behavior. The total moisture content of the facade element and the temperature range on the facade surface proved to be effective facadeindicators to assess the conditions of exposure to climatic degradation agents in the main orientations facade (N, NO, L, SE, S, SO, O and NO). Among the contributions of the thesis, we highlight the studies of the climate file with 13 years of hourly data measured by automatic station A001-Brasilia. Noteworthy are also the results of the experimental program of driving rain measurements addressed in situ, which allowed quantify driving rain coefficients directed to urban conditions of the city of Brasilia.
