Life Cycle Assessment of Tall Building Structural Systems - DIGITAL

The passage argues that while “green design” in tall buildings often focuses on reducing operational impacts, it frequently overlooks the full life cycle—especially construction and end-of-life stages. It highlights a disconnect between increasingly ambitious skyscraper construction and the lack of practical strategies for demolition or full life cycle planning. Using Life Cycle Assessment (LCA), the research evaluates the environmental impacts of building materials and processes across all stages. It compares structural systems in 60- and 120-story buildings, focusing on Global Warming Potential (GWP) and Embodied Energy (EE), providing both key findings and a methodological framework for future studies in sustainable tall building design.
