Assessing sustainable practices in architecture: A data-driven analysis of LEED certification adoption and impact in top firms from 2000 to 2023

Amid increasing global environmental concerns, the architectural industry is under increasing pressure to implement sustainable practices. Leadership in Energy and Environmental Design (LEED) certification has become a crucial benchmark for assessing green building practices. This study investigates the adoption and impact of LEED-certified projects within leading architectural firms from 2000 to 2023, utilizing a novel data mining framework to scan extensive datasets on LEED projects and firm operations. We introduce two key metrics: the Weighted LEED Achieved Score (WLAS) and the Green Impact Ratio (GIR), which evaluate the sustainability efforts of firms in relation to their market size and project scale. These metrics yield insights into how firms incorporate sustainability into their business and the environmental outcomes of their projects. Our research uncovers significant trends in LEED standard adoption, illustrating a strengthening commitment to sustainable buildings. The analysis underscores the strategic importance of these practices for securing a competitive edge and aligning with global sustainability objectives. This paper contributes to the sustainable architecture discourse by providing fresh insights into the integration and effectiveness of LEED certification among top firms and offering a comprehensive framework for evaluating the environmental and economic aspects of sustainability in architecture.
