The built environment is a key contributor, responsible for 40% of greenhouse gas emissions and consuming significant natural resources. To achieve decarbonization, tools for predicting environmental impacts are essential, especially during the design phase, which is crucial for reducing the long-term impact of buildings. Life Cycle Assessment (LCA) is the primary tool for assessing environmental impact, but it is a unidimensional approach. A more comprehensive method, Life Cycle Sustainability Assessment (LCSA), integrates environmental, economic and social dimensions. Despite its broader scope, LCSA remains underused in the building sector. Furthermore, BIM's capabilities in managing building life cycle data make it a promising tool for integrating LCSA into the design process. This chapter demonstrates the application of a BIM-based LCSA method on a real Spanish building, analyzing the impact of different materials and structural systems on sustainability. The results aim to assist architects and engineers in selecting the most sustainable building alternatives. This study emphasizes the importance of combining LCSA with BIM to enhance sustainability in building design, providing a novel and holistic approach to addressing the environmental, economic, and social challenges in construction.application/pdf25 p.engLife Cycle Sustainability AssessmentLife Cycle AssessmentBIMBuildingDecarbonizationStructural systeminfo:eu-repo/semantics/bookPartinfo:eu-repo/semantics/openAccess10.1016/C2021-0-02230-6
