What is the purpose of analyzing life cycle impacts of materials in LEED?

The purpose of analyzing life cycle impacts of materials in LEED is to understand materials’ environmental impact throughout their entire lifespan. This comprehensive approach allows for the consideration of various phases, including raw material extraction, manufacturing, transportation, installation, use, and ultimately, disposal or recycling. By assessing impacts across the entire life cycle, project teams can make more informed decisions that promote sustainability, reduce resource depletion, lower greenhouse gas emissions, and mitigate negative environmental effects.

Evaluating only the initial cost of materials overlooks the long-term financial implications and environmental costs associated with their use. Focusing exclusively on manufacturing location fails to provide a holistic view of sustainability and creates the risk of selecting materials that may have high environmental impacts elsewhere in their life cycle. Concentrating solely on the aesthetic aspects of materials neglects their performance, durability, and sustainability, which are critical factors in achieving LEED certification and promoting responsible building practices.
