RESUMO:
The creation of performance norm NBR 15575 originated the need to stablish parameters that could be assessed to identify the behavior used by the systems of an edification. Fulfilling these system's lifespan is intimately connected to how long they maintain their ability to resist to environmental influences. The façade, an element constantly exposed to weathering, shows a high probability of developing pathologies, compromising its durability and lifespan. The prediction of the conservation state of façade systems through models of degradation measurements could represent its behavior through the years. Thus, the present study developed a model to measure façade degradation called Degradation Factor (FDeg, in Portuguese), which allows the classification of pathologies according to its intensity, importance and relative cost. The Survey Method was used to select parameters and its ponderations, aiming for results through the perception of experts in this field. A case study of edifications with the studied coating types (finishing in paints and ceramic) was used to verify the applicability of this model. The edifications had different ages and exposure conditions and were situated in Salvador, Bahia. The results show that the model is applicable not only on the studied façades, but also those that showcase both types of finishing together. It was also realized that generally finishing in paint was more susceptible to pathologies, showing higher degradation levels, when compared to ceramic, with the same analysis criteria.
