Levantamento de manifestações patológicas em fachadas de edifícios verticais em Goiânia: influência da orientação solar e viabilidade do uso de dispositivos móveis

Abstract

This study investigates pathological manifestations in the façades of vertical buildings in Goiânia, analyzing the influence of solar orientation on the degradation of exterior coatings. The research identifies and classifies the main types of damage, such as cracks, detachment, efflorescence, and moisture stains, correlating them with solar exposure and environmental factors. To achieve this, a literature review and visual inspections were conducted in selected buildings, using images captured with a mobile device (smartphone). The performance of this device was compared to that of a professional camera in order to evaluate its effectiveness in documenting façade pathologies. The results indicated that north-facing façades show a higher incidence of cracks due to thermal variations, whereas south-facing façades exhibit greater moisture retention, favoring the proliferation of microorganisms. Furthermore, the findings provide technical support for construction professionals, assisting in material selection and the planning of building maintenance strategies. This research promotes more sustainable and effective façade maintenance practices, extending service life and reducing repair costs.
