Abstract

The construction sector significantly contributes to greenhouse gas (GHG) emissions, resource consumption, and waste generation, with structural materials accounting for up to 40% of embedded carbon. This study investigates the integration of Building Information Modelling (BIM), Finite Element Analysis (FEA), and Life Cycle Assessment (LCA) tools to promote sustainable structural design. Using a BIM model of a Valencian barraca, three scenarios were
evaluated: traditional materials (adobe and wood), concrete with steel, and concrete with Cross- Laminated Timber (CLT). Results show that natural materials generate lower impacts, while steel and concrete exhibit higher emissions. This work proposes a workflow integrating BIM, FEA, and LCA to incorporate sustainability metrics, ensure regulatory compliance, and support
informed decision-making. Key recommendations include improving Environmental Product Declarations (EPDs), developing structure-specific benchmarks, and achieving real-time BIMLCA interoperability.
