Green roof systems are living vegetation installed on the roofs and could contribute positively to the mitigation of urban heat island and enhancement of building thermal and environmental performance. Research study has been carried out to investigate the green roof technology and research in the world, with the aim to develop practical information for its applications in Hong Kong and other similar urban cities. The important factors for assessing the performance and designing the systems have been evaluated. This research paper highlights the key findings of the evaluation and discusses the benefits and potential applications of the green roof systems.
