ABSTRACT
The urban subsurface is a critical resource for addressing the rising energy and infrastructure demands of modern cities. Energy geostructures represent an innovative solution by integrating geotechnical engineering principles with energy functionality, offering both structural stability and renewable heating and cooling capabilities for buildings and infrastructure. Over the past three decades, extensive research has significantly advanced the understanding of various types of energy geostructures. This progress has led to the development of practical engineering tools, ranging from analytical to numerical methods. This study synthesizes these advancements and bridges the gap between theoretical research and real-world implementation. It explores key design methodologies and presents case studies of real-world installations, demonstrating their role in enhancing building and infrastructure efficiency and contributing to sustainable urban energy management.
