The United Nations (UN)’ aims to create synergy between all member countries to counter climate change, poverty, health and education. This initiative, part of a UN resolution called “the 2030 Agenda”, is intended to be achieved by 2030. The Architecture, Engineering and Construction (AEC) sector is the main sector in the world’ efforts towards to increase sustainability. For this reason, the life cycle thinking is becoming more widespread. The introduction of LCA analysis in building sector and the BIM technologies seems to be a key solution to tackle these problems. The goal of this research is to develop a workflow to integrate the Life Cycle Assessment (LCA) in the BIM environment and to create a tool able to monitor the environmental impacts of an architectural project, intercepting decision-making.
