jailcd2022035: The potential and challenges of green roofs in buildings based on the water-energy-carbon nexus

Abstract

This paper presents a quantitative study of the water-energy-carbon linkage in urban green space research in the context of the development of green roofs on buildings and from the perspective of three key policy issues where the water-energy-carbon linkage directly affects contemporary cities. Thus, the quantitative study of the water-energy-carbon linkage paradigm for green roofs on buildings highlights two perspectives on green roofs on buildings as urban green infrastructure for green roofs on buildings and ecology in urban landscaping, and discusses the advantages of developing green roofs on buildings under the water-energy-carbon linkage paradigm. This is followed by a discussion of the interrelationship between theory and practice, taking the broad development prospect and development space of sustainable building rooftop greening as an entry point. Finally, future research directions are proposed in terms of plant material selection, planting site deployment, ecological and environmental benefits and resource potential assessment in response to the challenges and opportunities brought about by the combination of the water-energy-carbon paradigm and rooftop greening.
