The growing interest in religious tourism, particularly in Muslim-majority countries, underscores the need for sustainable development approaches that align with Islamic values. This study explores how sustainable architecture can revitalize religious tourism sites while supporting energy management strategies guided by the principles of Maqasid Shariah. By integrating Islamic religiosity, visitor behaviour, and environmental stewardship, the research investigates how architectural design and infrastructure contribute to both spiritual and ecological well-being. A structural equation modelling (SEM) approach was employed to examine the relationships among Islamic beliefs, visiting behaviour, energy awareness, and support for sustainable design in religious spaces. Data collected from 350 Muslim visitors at selected religious tourism destinations indicate that Islamic religiosity significantly influences energy-conscious behaviour and attitudes toward green architecture. The findings reveal that religious commitment and visiting patterns are important predictors of energy management support, highlighting the potential of eco-conscious architecture in fulfilling the higher objectives of Islamic law—namely, the preservation of faith (din), life (nafs), intellect (‘aql), lineage (nasl), and wealth (mal). The study contributes to the discourse on Islamic environmentalism and provides practical guidance for sustainable architectural interventions in religious tourism planning.
