Advances in Constructional Engineering

With the growing adoption of sustainable development principles in urban planning, green building certification standards have become a focal point in commercial complex applications. This study examines two leading certification systems—LEED and GB (Green Building Certification)—by comparing their evaluation metrics, design requirements, and operational frameworks to analyze the cost-benefit relationship of green buildings in commercial complexes. The research demonstrates that while green buildings require higher upfront investments during design and construction phases, they deliver long-term economic returns through energy efficiency improvements, rental value enhancement, and extended asset lifecycles. Certification systems significantly boost brand value and market competitiveness, providing quantifiable decision-making support for commercial complex development and operations.
