Abstract

The study of green roofs is an interdisciplinary field recognized for its eco-friendly roofing
solutions. Green roofs offer ecological, economic, and societal benefits, making them an ef-
fective way to address urbanization's negative impacts. This review explores the evolution of
green roofs from ancient prototypes to modern innovations. Using the Google Scholar da-
tabase, we conducted a bibliometric analysis of 50 articles to assess publication rates in the
"green roof " area. Descriptive statistics were used to identify key contributors, ecosystem ser-
vices, research methodologies, and spatial scales in green roof studies. Our analysis showed a
rise in research on green roof technology in the early 21st century, with the United States and
China leading this research. Urban heat island mitigation emerged as a primary research focus
for green roofs, with cities being the most studied spatial scale. The most common keywords
were "green roofs," "urban," and "energy." This study thoroughly reviews the past and present
state of green roofs, showcasing a range of indicators that provide valuable insights for future
research and emerging trends in the area.

Keywords

Bibliographic compilation, ecosystem service, geographical distribution, green roof history, study methodologies
