A theoretical mapping of green roofs on building for sustainable constructions

Abstract

In 2019, the results of the national GHG inventory calculation showed a GHG emission level of 1,866,552 Gg CO2e in each industrial sector. This poses a significant challenge in the era of globalization. If construction continues with high carbon usage, climate change conditions in the coming years will likely lead to global warming of more than 1.5°C. One of the proposed agendas in the Indonesia Construction 2030 document is the promotion of sustainable development through the application of environmentally friendly building concepts. This paper aims to map the studies conducted on Green Roofs within the past 10 years and study their application in Sustainable Construction in Indonesia. The mixed method approach was used in this research. A total of 864 articles were gathered from the Scopus database, and a bibliometric analysis was conducted using the VOSviewer® application. The results indicate that the number of publications between 2012 and 2023, indexed by Scopus, was highest in 2020, with 110 publications. China emerged as the largest contributor in terms of publications. The most productive authors were Cabeza L. F. and Shushunova N., who produced 12 articles. The development of publications based on co-words resulted in three clusters. The application of green roofs in Sustainable Construction in Indonesia has already commenced, with notable examples such as the PT Dahana Campus and the University of Indonesia Library. These projects have demonstrated numerous benefits.
