GREEN ROOFS AS A DIRECTION OF SCIENTIFIC RESEARCH

Keywords: green roofs, sustainable development, climate change, air quality, precipitation.

Abstract

Green roofs are artificial ecosystems that provide a natural solution to environmental problems such as climate change and the urban heat island. Green roofs help save both cooling and heating energy; settle solid particles and reduce air pollution; control effluents and water pollution; increase the amount of biodiversity and ensure its sustainability, as well as have aesthetic and psychological benefits and thus play a significant role in ensuring the sustainable development of cities. The goal of this study was the systematization and analysis of scientific research in the field of green roofs. The analysis of literary sources was carried out using the VOSviewer program. The constructed cloud of bibliographic research consists of 4 clusters, which were conventionally named: "green roofs", "cities", "conservation of natural resources" and "water". An analysis of literary sources was carried out according to the main keywords of the corresponding cluster. In particular, two key terms were singled out in the green cluster (cities), namely atmospheric air quality and climate. Green roofs have the potential to reduce emissions of toxic pollutants when implemented on a large scale and can have a positive effect on air quality, and are also able to regulate the urban thermal climate thanks to vegetation that lowers the air temperature in the city and provides thermal insulation of urban buildings and structures. In the red cluster (conservation of natural resources), the most attention is paid to the terms carbon dioxide absorption, biodiversity and sustainable development. Grasses have been proven to offset more CO2 emissions over the life cycle of green roofs, and the annual carbon sequestration capacity of green roofs ranges from 0.37 to 30.12 kg/m2. Green roofs are not only a potential home for local biodiversity, but also provide refuge for rare and endangered bird species and provide a safe habitat for invertebrates and vertebrates in urban areas. A significant number of co-benefits have been demonstrated, covering a wide range of sustainable development areas, suggesting green roofs as a popular engineering application worldwide to combat climate change, mitigate urban heat islands, and improve air and water quality. The most iconic terms of the blue cluster (rain) are: rainwater collection and retention of runoff from roofs. Green roofs, due to their ability to retain precipitation, are an effective method of reducing the load on urban drainage systems.
