Resumo

The civil construction sector in Brazil is still marked by the predominant use of the conventional masonry method, which has become established due to its reliability, but presents challenges such as material waste and considerable environmental impact. In this scenario, the industry seeks more efficient and sustainable alternatives, such as monolithic EPS panels. These panels offer benefits in terms of thermal and acoustic performance, execution speed, waste reduction, and cost-effectiveness. EPS panels are made of expanded polystyrene, reinforced with galvanized steel mesh and coated with mortar, presenting lightness, versatility, high durability, and, additionally, being a recyclable material. Thus, this study was carried out to analyze the use of monolithic EPS panels as a replacement for the conventional block masonry system, through a literature review and a survey of case studies. To assess the competitiveness of monolithic and conventional construction techniques, a comparative cost analysis was developed based on data presented in indirect studies, making it evident that, regardless of the size of the residence, the monolithic EPS panel system presents a superior cost-benefit ratio compared to the ceramic block system. Furthermore, EPS stands out as a 100% recyclable, odorless, and low environmental impact material, significantly reducing waste generation on construction sites. Another important aspect is that, being prefabricated, the system eliminates waste and optimizes the use of resources, contributing to more sustainable practices. In medium-sized projects, the use of monolithic EPS panels has also been associated with cost reductions of up to 38% when compared to traditional masonry, mainly due to faster execution and lower labor demand. Standardization by ABNT, through standards such as NBR 16866:2022, ensures technical safety and consistency for its application, reinforcing its viability as a modern and efficient alternative.
