Development of Modular Green Roof Systems Based on Bio-Based Materials: A Cradle-to-Cradle Approach to Enhance Sponge City Principles, Rainwater Management, and Biodiversity

Ningning Wang

This doctoral research explores the integration of renewable bio-based fibres—such as hemp, wood, wool, and coconut fibres—into modular green roof systems. The project aims to develop innovative, biodegradable water storage mats with improved water retention and thermal insulation properties, thereby supporting climate-resilient architecture. By combining laboratory testing, life cycle assessment (LCA), and full-scale prototype implementation, the research seeks to quantify the environmental performance of these fibre-based materials. The findings will inform the development of regenerative urban infrastructure and provide scientific evidence to promote sponge city strategies and nature-based solutions (NBS) in sustainable urban design.
