Improving the Efficiency of Green Roofs Using Atmospheric Water Harvesting Systems (An Innovative Design)

Conventional green roofs, although having numerous advantages, could place water resources under pressure in dry periods due to irrigation requirements. Moreover, the thermal efficiency of roofs decrease without irrigation, and plants get damaged. Therefore, this study aims improve conventional by proposing a new multipurpose roof combined with fog dew harvesting systems. The analysis determined that average use summer (in humid regions) is about 3.7 L/m2/day, Mediterranean regions 4.5 arid 2.7 L/m2/day. During season, potential 1.2 15.6 between 1.6 4.6 1.8 11.8 during season 0.1 0.3 0.2 0.5 0.7 suggested fog/dew systems, summer, three different climates, show provide total requirement PV (photo-voltaic) panels 15 26% it higher impact on building, stormwater management, less dependence urban network, greater decreasing air, water, noise pollution. Finally, novel system consume shaded area mesh solar PVs maximize utilization area, as be applied same roof.
