Sustainable Construction and Technical Performance: The Durability of Ceramic Coatings According to ABNT NBR 15575

Objective: This study analyzes the application of ABNT NBR 15575 with a focus on the durability of ceramic coatings in façades, exploring the impact of material selection and application on the sustainability and longevity of buildings. Grounded in concepts of material durability and sustainable practices in civil construction, the research highlights the relevance of technical criteria and informed choices to reduce environmental impacts and improve building efficiency. The methodology combined quantitative and qualitative approaches, including the survey method and a structured questionnaire based on the Likert Scale, applied to industry professionals such as engineers, architects, sustainability consultants, and material suppliers. The quantitative analysis of data collected through an online platform was complemented by qualitative interpretation, enabling a comprehensive understanding of the results. These findings indicate that recurring issues, such as cracks and detachment in façades, are associated with inadequate practices in material selection and application, compromising the durability and sustainability of buildings. The study provides practical guidelines to enhance compliance with ABNT NBR 15575, promoting more durable buildings with lower environmental impact. By integrating sustainability and technical performance concepts, the research contributes to advancements in civil construction, offering practical recommendations to improve durability and reduce the environmental impacts of ceramic-clad façades. Theoretical Framework: The research is based on studies on the evolution of ABNT NBR 15575, emphasizing the integration of sustainability concepts into material selection and the environmental performance of buildings. The theoretical foundations include analyses of durability and sustainable practices that promote more efficient constructions with lower ecological impact. Method: The methodology combines a literature review on durability and sustainability, the application of Likert scale questionnaires, and field research for empirical data collection. These methods help identify gaps between current construction practices and normative requirements, focusing on environmentally responsible solutions. Results and Discussion: The results highlight that many of the practices analyzed present challenges in both durability and sustainability. Gaps in material selection and execution negatively impact environmental efficiency and building performance. The discussion addresses the results from the perspective of sustainable construction, emphasizing strategies to minimize pathologies and extend the lifespan of façades. Research Implications: The research proposes practical guidelines that integrate durability and sustainability as fundamental pillars. These contributions aim to reduce pathologies in façades, optimize resource use, and promote environmentally responsible construction practices. Originality/Value: This study stands out by offering a detailed analysis of compliance with ABNT NBR 15575, proposing practical and sustainable solutions based on empirical data. The research adds value to the sector by integrating sustainability as a central axis for more durable buildings with a lower environmental impact.
