The context of sustainability in construction focuses on various areas, with Life Cycle Assessment (LCA) as the main tool, aiming for a holistic approach. SIDAC (Sistema de Informação do Desempenho Ambiental da Construção), based on LCA, simplifies environmental data for civil construction in Brazil. This study aims to show how the application of this tool helps with the sustainability of single-family buildings. SIDAC data were used to evaluate three models of single-family homes. The main result was the difference in carbon emissions and primary energy demand between the building models. The high-standard building had the lowest impact according to floor-plan area and useful life. However, when assessing the impact per resident or the total impact of the building, the low standard had the lowest impact. This analysis shows how SIDAC can help in discussions about the impact of buildings and the most environmentally relevant materials. SIDAC is a high-potential initiative for the sustainability of the built environment.
