Life-cycle assessment (LCA) is a critical methodology that can be used by building design professionals to evaluate the climate impact of their projects. Participants will learn life-cycle assessment (LCA) terminology and basic concepts, how to incorporate LCA in design workflow, and how to conduct an LCA for a building project using the LCA tool Tally. Participants will be introduced to the Embodied Carbon in Construction Calculator (EC3) Tool, a free and open-source database of environmental product declarations (EPDs), and learn how Tally and EC3 can be used to inform specifications and achieve LEED points. The course can be held virtually or in-person and is a combination of presentation, discussion, and in-session exercises.
