The synthesis helps designers and researchers move beyond one-factor recommendations.
Urbanization replaces permeable surfaces and changes runoff, while green-roof performance varies with design, climate, vegetation, age, and maintenance. The review asked how those interacting factors can be considered together.
The paper synthesized green-roof hydrology research across six factor groups: roof geometry, substrate and growing media, climate and rainfall, vegetation, roof age, and maintenance. It compared findings, noted inconsistencies, and identified underdeveloped research questions.
The synthesis helps designers and researchers move beyond one-factor recommendations. It frames green roofs as living stormwater systems whose performance depends on both initial design and long-term care. Read together, the question, method, and findings show how this publication fits within Tafazzoli’s broader program of connecting built-environment evidence with practical decisions. The page intentionally separates documented results from interpretation and directs readers to the complete paper for methodological detail. The study also illustrates a recurring principle across this research portfolio: a useful result must be understood in its original setting before it is transferred to another project, organization, population, or policy context.
