The article examines the concept of green roofs and their impact on the microclimate of urbanized areas. The design features of green roofs, the principles of their functioning and the advantages of their implementation in the urban environment are described. The main attention is paid to environmental and energy aspects, in particular the ability to reduce the “heat island” effect, improve air quality and reduce the energy consumption of buildings. The prospects and challenges of integrating such systems into modern urban infrastructure are also analyzed.
