Desenvolvimento de um modelo de casa contêiner para a zona bioclimática 07: eficiência térmica por meio da orientação solar, seleção de materiais e estratégias bioclimáticas

Abstract

This study investigates the feasibility of building container homes in Morada Nova - CE, focusing on thermal performance and the effectiveness of different insulation materials. The study was based on the NBR 15575-1, NBR 15220-3 standards, and RTQ-R (2010), which provide guidelines on thermal comfort in buildings. It included computational simulations and experiments with insulating materials such as polyurethane foam, rock wool, and glass wool. Internal temperatures were assessed during the colder (June) and hotter (December) months, considering the influence of facade orientation. The results indicated that facade orientation had no significant effect on internal temperatures, with minimal variations between north and west orientations. Among the tested materials, polyurethane foam exhibited the best thermal performance, followed by rock wool, and lastly, glass wool. All configurations were effective in maintaining comfortable internal temperatures throughout the year, with polyurethane foam standing out for its superior thermal efficiency. The results confirm that the strategies adopted for the container home construction meet the normative standards for thermal comfort, demonstrating the feasibility and effectiveness of the proposed design. Future work is recommended to explore other bioclimatic zones and test new passive technologies and construction methods, as well as to conduct field validation to strengthen the obtained conclusions.
