A big change in LEED rewards designers who use life cycle assessment (LCA) to verifiably reduce the environmental impact of buildings. Three points are available and they’re easier to achieve than they look. The new credit is Option 4 of the “Building life-cycle impact reduction” credit, part of the big leap forward in the LEED v4 materials and resources credits. This session will provide an overview of LCA and the new credit, and present a case study demonstrating how it might be achieved on a project. The session is intended for architects, engineers and consultants familiar with LEED and green buildings, but perhaps not as familiar with LCA. It will enable designers to understand not only how to achieve these LCA points on a LEED project, but also how to use life cycle assessment to quantify important metrics in sustainability performance of a building. It can make a real difference on your next building.
