More than the sum of the parts: System analysis of the usability of roofs in housing estates

Urban Farm DB summary

This study developed an integrated framework for designing sustainable roof mosaic scenarios, combining urban farming, solar energy, and rainwater harvesting on unused rooftops of housing estates. Applied to a 66,433 m² rooftop area, the framework involved multi-scale and multi-dimensional analysis. Five participatory-designed rooftop scenarios were found to improve residents' resource self-sufficiency, providing 42–53% of vegetable consumption, 9–35% of electricity, and 38–200% of water needs, depending on the scenario.
