Simulation-Based Life Cycle Assessment for Office Building Façade: A Case Study of the Leadenhall Building in London

High-rise glazing systems are among the most important components affecting energy efficiency. Through lens of Life Cycle Assessment, glass has always been an unlikely material for large buildings due to its considerable consumption throughout pre-use and post-use phases. Moreover, use high-tech materials a negative impact on environment. Therefore, present study aims assess comparative life cycle four different system technologies (BIPV, smart glass, low-E, double glazing) representing used commercial high potential systems. The next step optimized Leadenhall iconic tower as case study. In this analysis, simulation is combined with assessment investigate environmental impacts. ZEB-COM tool, Rhino®, Grasshopper® have calculate emissions, 3D modeling, respectively. results reveal that BIPV achieved 37% total energy-saving stood first. A hybrid solution (two systems) proposed eliminate aspects increase livability. Although it can generate almost 30% less than complete installation, specific design by authors, cover aesthetic concerns in compensates 27% demand project.
