The designers can play an important role in the planning, design, and current research that is shaping the green roof industry. A green roof design system may be designed as a retrofit to an existing building or a new installation to a planned building, and both options require nearly the same principle design processes. The design team may typically consist of architects, landscape architects, and structural and mechanical engineers. Architects and engineers are required to design and certify drawings that consist of design elements of modifications to waterproofing, parapets, and utility routing. Green roof technology's benefits, such as improved stormwater management, urban ecological enhancement, urban heat island reduction, and energy conservation make it an attractive tool for designers. Landscape architects should maximize the green roof system benefits and associated cost savings through a thorough design process that leads to a full integration into the building and site design.
