Measuring Sustainability: Integrating KPIs and Islamic Architecture for Green Tourism Excellence

Green tourism infrastructure is essential for achieving sustainability goals in the tourism sector. This study explores the integration of Islamic architectural principles in eco-tourism projects in Iran, using a KPI-driven framework to assess their impact. The research employs a mixed-methods approach, incorporating a comprehensive literature review, expert interviews, and case study analysis. Findings reveal that Islamic architecture significantly enhances cultural integration, environmental sustainability, and operational efficiency in tourism initiatives. Key Performance Indicators (KPIs) such as energy efficiency, renewable energy use, community engagement, and cultural preservation are identified as critical metrics for evaluating and improving green tourism infrastructure. This study highlights the importance of culturally aligned KPIs in promoting sustainable tourism practices and offers actionable insights for policymakers, architects, and tourism developers. The research also identifies gaps in current KPI frameworks, particularly in integrating cultural and environmental metrics, and provides recommendations for future studies to advance the standardization of green tourism evaluation.
