Análise comparativa entre sistemas de vedação com blocos cerâmicos e EPS em habitação de interesse social

Abstract

In Brazil, the construction sector plays a central role in socioeconomic development, especially given the housing deficit that still persists, estimated at millions of units mainly targeted at low-income populations. Considering the choice of wall systems as one of the essential stages in a building project, a comparative study was carried out between ceramic block and expanded polystyrene (EPS) wall systems, addressing constructive aspects and the evaluation of thermal performance and costs of a social housing unit located in bioclimatic zone 4B, in Goiás. The methodology included thermal performance simulations using the Termus software, based on NBR 15575 (ABNT, 2021), and a comparative cost analysis of each material in the current context (SINAPI, 2025). For this purpose, a standard residential project from the Goiana Housing Agency (Agehab), built in the region of Buriti Alegre, Goiás, was used. The results obtained indicate significant differences in thermal transmittance, highlighting the potential of EPS as a viable and sustainable alternative for social housing projects. Additionally, a cost analysis of each material reinforces arguments regarding the choice between them.
