Yes, the intensive CAM green roof at the University of Cagliari has strong potential for replication and upscaling. Its modular and simple design, based on a 30 cm sandy soil layer and low-maintenance CAM vegetation (Agave americana), allows it to be easily reproduced on other roofs without extensive technical modifications. The system’s ability to collect and retain rainfall, reduce runoff peaks, and convey excess water to storage tanks makes it suitable for urban-scale deployment, particularly in Mediterranean climates or cities seeking climate-resilient stormwater management solutions.
Large-scale adoption could enhance urban flood mitigation, support biodiversity, and contribute to climate adaptation strategies, demonstrating the broader applicability of this intensive green roof model in diverse urban environments.
