Green roofs play a multifaceted role in architecture, with a primary focus on enhancing thermal performance and managing stormwater. The vegetation planted on green roofs acts as an insulating layer, reducing heat transfer between the building and the outside environment. This naturally contributes to lower energy consumption for heating and cooling, thus improving the building’s overall thermal efficiency.

Additionally, green roofs are effective in managing stormwater. They absorb rainfall, which helps to reduce runoff and decrease the burden on city drainage systems. By capturing and utilizing stormwater, green roofs can mitigate flooding and erosion, contributing to better urban water management practices.

Beyond that, the diverse ecosystems that form on green roofs can enhance biodiversity, providing habitats for various species and improving urban air quality. While aesthetics and the potential for creating additional living spaces are benefits associated with green roofs, the primary function and most impactful roles are their contributions to thermal regulation and stormwater management. This makes them an integral part of sustainable architecture and urban design.
