Commercial Building Roof Greening Hand-drawn

Quick answer：

Roof greening on commercial buildings involves the process of planting vegetation on the rooftops to improve the building's energy efficiency, reduce urban heat island effect, and provide additional green space. Hand-drawn illustrations of such projects typically depict the architectural design of the building, the types of plants used, and the overall layout of the green roof. This form of visualization helps in conveying the design concept and feasibility of the roof greening project.
