Additionally, the cost of installation, maintenance, and potential savings in energy consumption should be taken into account to ensure the long-term viability of the green roof. Lastly, collaboration with architects, engineers, and landscape designers is essential to ensure that the green roof is designed and implemented effectively to achieve its environmental and aesthetic objectives.
