Pattern Analysis of LEED v4 Rating System

Green building design and construction are important in mitigating the health and environmental effects of indoor air pollution and climate change. The Leadership in Energy and Environmental Design (LEED) rating system becomes essential for ensuring cost-effective, healthy, and environmentally friendly buildings. While the list of LEED certification credits can collectively contribute to sustainability in buildings, the comprehensive compliance of LEEDcertified buildings with the entire list is still questionable. In this respect, this study investigates the key categories contributing to the highest LEED scorecard points and explores the relationship between different LEED rating parameters. This study compares LEED ratings of 40 buildings certified by LEED v4 with the highest point totals and analyzes their scorecards in various categories. The findings suggest how different LEED categories can be synergized with each other for an effective certification process. The patterns of current LEED certified buildings can be used to advance green building practices and can guide future research directions, ultimately contributing to sustainability in built environments.
