The global emphasis on sustainabilitySustainability hasGreen buildings urged an amplified interest in green buildingsGreen buildings, which are designed to minimize environmental impacts and maximize economic and social advantages. Life Cycle Cost AnalysisLife cycle cost analysis (LCCA) and Life Cycle Budget DevelopmentLife cycle budget development (LCBD) are fundamental in evaluating the economic viability and long-term sustainabilitySustainability of green buildingsGreen buildings. These tools facilitate informed decision-making, cost optimization, and the creation of more sustainable and resilient structures, aligning with the overarching goal of sustainable development. Despite their importance, the application of LCC in the construction sector is constrained by the lack of standardized methodologies, tools, and benchmarks. This study demonstrates the application of LCCA and LCBD to evaluate a green buildingGreen buildings in Tirana, Albania. The research methodology encompassed a thorough review of existing literature, an examination of green buildingGreen buildings case studies within the Western Balkans, and the creation of a region-specific framework. This framework facilitates the comprehensive identification and quantification of costs associated with the entire life cycle of green buildingsGreen buildings, from design and construction to operation, maintenance, and end-of-life stages. The findings reveal that green buildingsGreen buildings are economically viable, with long-term savings from reduced energy and water consumption outweighing initial design and construction costs. Incorporating green buildingGreen buildings features from the design stage significantly influences life cycle costs and budgeting, particularly in reducing operation and maintenance expenses. Energy costs represent approximately 26.5% of the total life cycle budget, and reducing energy consumption is identified as the most influential factor in minimizing total life cycle costs. The application of LCCA and LCBD in the Albanian context offers valuable insights for policymakers, building owners, and developers in the region, highlighting the economic and sustainabilitySustainability benefits of green buildingsGreen buildings. The study contributes to the expanding literature on green buildingGreen buildings economics and lays the groundwork for further research and development of sustainable building practices in Albania, the Western Balkans, and beyond.
