Collapsible Roof Greening Diagram

Quick answer：

A collapsible roof greening diagram typically showcases a design for a roof that incorporates greenery. This can involve a system of plants and soil layered on a roof, which can be expanded or collapsed. Such systems are used for aesthetic, environmental, and functional benefits, including improved insulation, stormwater management, and biodiversity. The diagram would illustrate the layout, materials, and mechanisms for the roof's collapse and expansion, as well as the plant species to be used.
