Cost analysis and feasibility of green building adaptation in low-rise residential housing: Evidence from Türkiye

This study evaluates the cost implications of green building practices in low-rise residential housing by analyzing three sample houses in Kayseri, Türkiye. It compares traditional construction systems with green alternatives, focusing on water efficiency, energy-saving technologies, and sustainable materials. The findings reveal that green buildings incur higher upfront costs, particularly due to photovoltaic systems and certified materials. However, when compared with traditional structures, they demonstrate clear long-term benefits in energy savings, environmental performance, and operational efficiency. Water-related costs were mainly driven by sanitary fixtures and appliances, while insulation dominated material expenses. By offering a localized cost comparison between traditional and green construction, this study fills a gap in the national literature and highlights the feasibility of sustainable housing in Türkiye. These insights aim to inform both policy development and practical applications, providing a valuable foundation for integrating green certification systems into future low-rise residential projects.
