Abstract
Green building construction projects are increasingly recognized as essential for advancing environmental sustainability and reducing the ecological footprint of the built environment. However, the perception of higher upfront costs remains a barrier to their widespread adoption. Cost optimization models provide a pathway to balance financial viability with sustainability goals, making them a critical focus for both researchers and practitioners. This synthesizes the existing body of knowledge on cost optimization models applied to green building construction projects, with the objective of identifying prevailing approaches, evaluating their effectiveness, and highlighting areas for future advancement. This followed PRISMA guidelines, with searches conducted across major scientific databases to capture peer-reviewed articles, case studies, and technical reports published over the past two decades. Inclusion criteria focused on studies addressing explicit cost optimization strategies, economic evaluation methods, or decision-support frameworks in the context of certified or sustainability-oriented building projects. Models identified were categorized into economic and financial models (e.g., life cycle costing, net present value analysis), operational and resource-based approaches (e.g., value engineering, lean construction), technology-driven solutions (e.g., BIM-enabled cost simulations, machine learning forecasting), and integrated multi-criteria decision-making frameworks. Comparative analysis revealed that while economic and financial models remain foundational, emerging digital technologies and hybrid optimization techniques offer greater potential for achieving both cost efficiency and long-term environmental benefits. Findings also indicate persistent challenges, including limited empirical validation of models in real-world projects, regional disparities in adoption, and insufficient integration with advanced digital technologies. This concludes that cost optimization for green building construction requires multi-disciplinary collaboration, policy support, and stronger links between financial modeling and sustainability outcomes. Future research should focus on AI-enhanced decision tools, renewable energy integration, and context-sensitive frameworks that align cost efficiency with global sustainability targets.
